I have a simple datagridview that I fill from a mysql database using the latest mysql connector.net.I configured my columns in the datagridview collection and the data displays fine.I don't want the user to edit data directly in the grid so my datagridview is not readonly but all my columns are except the checkbox one. If I set the datagridview readonly I can't check my checkboxes.I added a checkbox column to be able to delete multiple rows easily but I can't uncheck a checkbox.
Let's say I have 3 rows in my datagridview I check line 1 checkbox- I check line 2 checkbox- I uncheck line 1 checkbox- I check line 3 checkbox As soon as I check line 3 checkbox, line 1 checkbox becomes checked "automagically"
After a successfull bindingsource.AddNew(), .EndEdit(), TableAdapter.Update(), i'm trying to get the value of the PrimaryKey from the newlly added record wich is always = -1!

I have a VB 2008 program that has a number of forms. When I run the compiled program on a different computer, the form appears different. The relative position of various controls on the form are different. Its as if the controls have been repositioned. Resizing the form does not correct the problem. The only difference between the two machines is the size and resolution of the screens.
i have simple application which contain one listbox.i am loading item in listbox from one file. around 130000 items in it.when i run this application on xp computer i am able to scroll down all item perfectly from first to end.But when i run this application on vista machine, it only shows 50% of item if i scroll down with that bar on right on listbox. but when i reach end of list (which is item number 65000) and than use "Down arrow " of listbox it move to item n umber 65001 and later and scroll bar move again center of listbox.After i move to record number 65001 and more by clicking down arrow and use scroll bar at center to move further down to end it again shows 65000 item.
I develop my VS2010 project in my laptop with SQL 2008 Standard. In my laptop everything is working good, using the following connect string as global public string when the main form loads:
I have a DataGridViewCheckBoxColumn who's column name is "booReadyToReport want to hide all the checkboxes in this column if "bintAnalyteCodeID" doesn't equal the selected value in a combobox on my form. ut I run this bit of code the DataGridView DataError event fires currently, have nothing in the event except an comment. he code seems to work, but I'm new to VB.NET and I'm wondering if this is the correct way to handle thishould I use the CellPainting event?
highlight rows with RBF3 For Each dr As DataGridViewRow In Me.dgvCalculatedResults.Rows f dr.Cells("bintAnalyteCodeID").Value = Me.cbxAnalyte.SelectedValue Then
Dim Comp = From C In db.Table1 _ Select C.Completed, C.Taken, C.Namne Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
I have a datagridview with 2 columns, one is text box and another one is check box column. My problem is that when i check or uncheck on cell of check box column i just want to show a value of this cell but it show opposit to it real value, it mean that when i check on this cell its value is false so this result is not correct .
I have a DataGridView with a checkbox column. I want to capture the value of the checkbox immediately when user changes it by clicking. I tried several events (CellValueChanged, CellClicked, CurrentCellDirtyStateChanged etc.) but nothing worked.
This is my code:
If dgvIDsTBC.CurrentRow.Cells(2).Value = True Then MsgBox("True") End If
i have a datagridview that loads three columns from a datatable. i want to add a fourth column that needs to be a checkbox column. if i add the checkbox column at design time it is always my first column. i want it to be my last column after my datatable columns. how can i accomplish this?
I have a datagridview that is bound to a binding source.I used the following code to add a checkbox column to the datagridview:
Imports System.Windows.Forms ... Dim newcolumn as DataGridViewCheckBoxColumn Datagridview1.Columns.Add(newcolumn)
The checkbox column shows up successfully, but when I try to click any of the checkboxes,nothing happens.The cell remains unchecked.It blinks, so I know that it is acknowledging the click, but the checkbox state does not change.
Can I show checkboxes to the column headers in datagridview for each column in my dgv I Used [url] for help but it replaces the header cells one by one .Can I use any property of dgv which shows checkboxes for all column headers
i'm populating a datagridview from a sql server db. so when i select an item from a combobox and then a date from a monthcalendar i populate my dgv based on the classid of the combo and the weeknumber of the monthcalendar like this:[code]
I use a code for place a CheckBox Column, into a DatagridView.This CheckBox column is the last Column of the DataGridView.Now i wants the CheckBox column at the first place of the datagridView.The DataGridView is filled from a database with several Columns.Can i place the Checkbox to the front?this is mij code, that place the CheckBox on the last place..[code]
i am developing an application in VB.net implies some datagridview operations. the appl contains one DGVW with columns fixed programatically, one such column is Datagridviewcheckbox column. the datasource for dgvw is bounded by a datatable. the user needs to enter the values in the GUI.
supposing the user enters the 2x2 matrix values, and the user checked the checkbox last cell in the dgvw. The problem - the last cell value is not updating inside. if ii debug through code, the "cell(2,2).value" reurns null value whereas the rest of them returns the value what i entered.
if i clicked the mouse some where in the dgvw after entering the last cell value, then it is returning the exact value as expected.
I have a datagridview on my windows form bound to field "STATUS" in SQL database with the default value of 0.What i want to acheive is that for each row in the datagridview, if user clicks the checkbox column only it should display a message " LOCK THE ROW?". If user chooses yes then the entire row should become readonly including the checkbox check "Greyed out" or disabled for that particular row and update value to 1 in the database field.I created checkbox by:
'on form Load_Event Dim colCheckbox As New DataGridViewCheckBoxColumn() colCheckbox.AutoSizeMode =DataGridViewAutoSizeColumnMode.ColumnHeader
I'm trying to render a checkbox in a datagridview column header so that when the checkbox is checked/unchecked all the cells in that column should be checked/unchecked accordingly.The datagridview is bound to a database table but the column containing the checkbox header cell is unbound. The problem is, whenever i click the header checkbox, all the cells in that column are checked but the header checkbox itself gets invisible. If I click the HEADER (though the checkbox is invisible, still I can click the header) again, all the cells in the column below are unchecked and the header checkbox becomes visible and unchecked. Everything is happening as expected except the visibility of the header checkbox. Why is it so?
''' <summary> ''' The custom class for checkbox header cell. ''' </summary>

I have a userform which allows my users to go through numerous comboboxes to select a combination of items they want displayed in a datagridview. My datagridview is populated from sql queries to my database(s), depending on the choices made in the comboboxes. The first column has checkboxes so my user can pick which rows they want to keep. Once they've chosen what they want, they click a button to save those rows into a seperate sql table.
All this works well, but here's my problem. After they click the button to save to the table, or another button which simply clears the datagridview without saving to the table, I want to clear my datagridview. While it seems to work, after all my comboboxes are cleared, and I go through another iteration of choices, and I display all the rows again in the datagridview, I get a second column of checkboxes.
Right now the checkbox column is added right before the datagrid's datasource is set. I've tried adding this column outside the subroutine that populates the grid, but it doesn't work.And I've tried numerous ways to delete this column so it will be regenerated when the datagridview is repopulated. Different things either give me errors or bomb when I compile.how to remove a checkbox column from a datagridview for good?
I am trying to add a checkbox column to a DataGridView in a simple window forms application.
I am pulling back some data from a database using ADO.NET, putting into a datatable, and then setting the datagridview datasource to the datatable. I then want to add a checkbox column as the second column. So far I have this code that seems to work:
' Code here to connect to database Dim da As New SqlDataAdapter(cmd) Dim dt As New DataTable
[Code].....
This code 'works' and I get MyDataGridView to show the data with the checkbox column in the correct position in the table.
However, for some reason, I cannot check any of the check boxes in the DataGridView? I have tried lots of things (e.g.altering the readonly state of the column) but cannot get it to work.
I have 2 DatagridViewChecKboxColumn. What I want to happen is that a (Submit)button will be disabled until the checkbox2 will be checked. How will I do this if my checkboxes are DataGridViewCheckboxColumn? What loop will I do,because there's a possibility that I'll be checking the last checkbox?
CheckboxColumn1 is "Parent" and CheckboxColumn2 is "Child", they are related to each other. It's a requirement that the Parent has to have at least 1 Child meaning it can be One(P) is to ManyŠ or One(P) is to OneŠ. If the user didn't meet the said requirement, the system should not allow him to insert the selected records to the database. That's why I've decided to Disable the button unless the user checked the two checkboxcolumn. Meaning if the user only checked the checkbox/es in the Child column, the button will remain disabled, same concept with the Parent checkboxcolumn. The button that I'm talking about is what I call "Consolidate Button".
I tried this:
Private Function HasParentAndChild() As Boolean Dim result As Boolean = False Dim hasParentCode As Boolean = False
[code]....
I tried this, but still not working. It does disable the button but in random clicks/checks meaning after 3 clicks in anycheckboxes the button will be disabled and be enabled again after how many clicks. Dont know what the problem is. Tried to debug but I dont get it.
i am developing an application for generating xml file with some details inside and regenerating it whenever i need.Step1: In the user interface,i have placed a gridviewcontrol during run time. i used Datatable for building the table and assign this table as datasource to the datagridview control. last column("GHI") is a checkbox column and its is successfully viewable in the datagridview. the snippet is like this.
dim iDGVWCount as integer iDGVWCount =1 Dim oDGVW As DataGridView
[code]....
Step 3: if i reopen this xml file and populate the celll details in datagridview, the column 'GHI' is not viewable as checkbox column. it is simply shown like an ordinary cell. the snippet for opening the xml file is shown here.
dim ds as dataset ds = New DataSet ds.ReadXml("C: estxml.xml")
[code]....
Question1 : is there any setting needs to be done for bring back this checkbox column automatically in the datagridview while reading from the xml file.
Question2 : how we can bring the value of unchecked column as false in the xml file. the node is included in the xml only if a checkbox is checked.
I'm facing a strange problem in my dgv, I have the dgv bounded to a datatable, now I had to add a new column to let the user checks the rows that he/she want to export to a text file. I had the checkbox column, but when I run the application I can't check any row, I try to add in the click event of the dgv to manually check the column but it still not works...
My VB da.SelectCommand = com_pfda.Fill(ds, "table_1")dgv_dados_obra.DataSource = ds.Tables("table_1") Dim dgvColunaCheck As New DataGridViewCheckBoxColumnWith dgvColunaCheck [Code] .....
The code in the click event, because the normal click in the checkbox doesn't worked: VB If e.ColumnIndex = 7 Then If dgv_dados_obra.Item(7, e.RowIndex).Value = 0 Then dgv_dados_obra.Item(7, e.RowIndex).Selected = True [Code] ..... I don't know why this doesn't work...
I have an unbound datagridview control whose first column is a combo box This contains a list of part numbers.I am having some problems with the datagridview automtically adding a new row when the combo box item is selected.If I select an entry from the data by typing in part number in full in the first row and pressing tab or enter then I get a new row created. No problems.However, if I then START typing a part number in the second row AND click on the part number in the list that is suggested then I DO NOT get a new row.However, if, on the first row I START typing a part number AND click on the part number in the list that is suggested I DO get a new row.
My code is as follows:
Private Sub dgOrders_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles dgOrders.EditingControlShowing Try
