Add An Unbound Checkbox To A Datagrid In .net 2003?
Apr 9, 2010
I'm writing an Windows Form Application and need to add an unbound checkbox to a datagrid.The datagrid displays the fields of an Access 2007 table and I need the checkbox to give the user the option to select/deselect any of the records shown in the datagrid. After the user clicks on a button, the application must read the whole datagrid to detect what records were chosen by the user and process each one accordingly.I tried using TableStyles but as this new column is not part of the database, it won't work.
I'm seriously about to abandon this DataRepeater. I don't want to. I want greater design control than the DataGridView. I've played with various Events for days and have settled on the CheckBox.CheckChanged Event.
What I'm trying to accomplish: My Bound DataRepeater has an UnBound CheckBox in each DataRepeaterItem.When the user 'Checks' the CheckBox, I want to change the value of a NumericUpDown Control to the value of a hidden, Bound Label.
[Code]...
This causes other, seemingly random, DataRepeaterItems (Rows) to also become Checked and thus it's NumericUpDown value to change.Am I going about this from the wrong angle? Can't see the forest for the trees?
I'm using an unbound datagrid to make a balance sheet and I need to have a certain row sum the previous rows but it only concatenates (obviously the cells default as strings but I don't know how to fix it). I've really only worked on VBA and this is my first crack at .net Here's what I've tried that is wrong:
I have created an Unbound DataGridView. It has has 4 Columns Name, Last Name, Picture, CheckBox. I would like to do change the checkbox's enabled state true or false (editable or not) at the time I add the row
Not its checked state :) and would also like to change image that is placed in the Image column cell during the add row.
I have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?
Private Sub UpdateSellFor(sender As System.Object, e As System.Windows.RoutedEventArgs) Dim _CB As CheckBox = DirectCast(sender, CheckBox) Dim _ID As Integer = _CB.Tag Dim _PP = DirectCast(DG_PartsToSelect.CurrentItem, PartTyping).PartPrice
I am creating a Microsoft Access 2003 database which will be using Visual Basic code in the backend.I have a form called frmReports. On this form are three option groups consiting of checkboxes. What I want to happen is if one of the checkboxes is checked, then the other two option groups are made invisible.
The context of the problem is a teacher is reporting on pupils. If a pupil is marked as being absent from class, the other two option groups (Behvaviour and Homework) disappear as no other information can be input.
I am printing a files that are shown in datagrid.. But I want to choose a file that I don't want to print by checking the checkbox that I added in datagrid..
I have here the code for printing.. Anyone can edit my code that will print those file that is not checked.
Code:
Try openMySQL() Dim sql = "DROP TABLE IF EXISTS dummydisconnectionorder"
I was wondering the best method or code to Sum\total a bunch of cell values of an unbound column in a datagrid to a textbox string. this request is 100% genuine...im not some student trying to get you guys to finish my project, this is purely for educational and personal information for myself. im new to vb.net.
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.
just would like to ask if it is possible to manually populate the datagrid in asp.net 2003 using vb.netwe usually populate the datagrid using this code, in this code what it does is it populate the datagrid base on your query , it's automated you can't edit or evaluate the data inside.
dataGrid.DataSource = ds dataGrid.DataBind() What if if I want to edit or evaluate the data inside the DataSet?
I am new in programming and I'm making an application that can filter records on datagrid from the user's input in textbox..I tried this code that I also got here.. But I'm getting an error.
ERROR MESSAGE:An unhandled exception of type 'System.InvalidOperationException' occurred in system.data.dll Additional information: Fill: SelectCommand.Connection property has not been initialized.
I am working with Vb.net. See the code below; I have the following problem - when I click the checkbox (Cells(3)) the value remains 0.00 in Cells(4) unless I click another checkbox is when Cell(4) gets populated with the value from Cells (5).
What I want it to do is when cells(3) is checked, Cells(4) should be populated instantly with the value from Cells(5). Rather than still show 0.00 until another checkbox is clicked. I think th eproblem is in the eventhandler as highlighted

I am limited to using ASP .NET 1.1, as for this environment I cannot upgrade to 2.0 or beyond Essentially, I have a very simple datagrid that has a checkbox in one of the columns, which is a template column...the code for the datagrid is this:
Now, my issue is that when I set cbStaticRolling to the CheckBox control through FindControl on the e argument, it seems to set the variable okay, but doesn't seem to be setting the right one, or setting it properly, because "Checked" property is false regardless of whether I check the box or not?
and when a user clicks on cell4, it's supposed to add the value of "Holiday" to my database and all of the data from that line. What's happening is that I can't even click on the checkbox.
I have the following Private Sub holidaysaveButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles holidaysaveButton.Click For Each dr As DataGridViewRow In DataGridView1.Rows
[Code]...

I have a datagridview that is connected to a table from my database. It displays all the records from that table. The question is this, how can i put a checkbox column on my datagrid for me to be able to delete multiple records from my database? I am using visual basic .net 2005.
I have a tbl called tblProjectpatients which also has 2 fields Yes and No (these have the data type - Bit).
These two fields have been populated with false and true values.
On my form, I have a datagridview which is populated with various values from tblProjectpatients.
The problem am facing is that the checkbox's for Yes and No on the datagridview are empty at runtime eventhough at the backend they have either False or True values.
I am expecting the checkbox showing on the datagridview to be either checked or Not Checked depending on the True or false values.
i want to ask about the check/uncheck the checkbox in a column in datagrid.if all row in the checkbox column is not selected, what is the code is.because i want the msgbox appear if the user not check any row.
I haven't seen a related thread (yet)I have a VB windows application that uses a datagrid to display a text column and a checkbox column. Only one row in the display can have a checkbox entry = true. If a checkbox is selected, the app is to search the rows and all other checkbox entries are to be set to false.My event handler is: Private Sub dgMember_CellContentClick(ByVal sender As System.Object, ByVal e As ystem.Windows.Forms.DataGridViewCellEventArgs) Handles dgMember.CellValueChangedI first had to have this handler code check a flag and exit if true (when initializing the display) because it was called for each row during initialization.
I created 10 checkboxs dynamically. I am using DataGridView. According to Checkbox Checked the corresponding data will display in the Datagridview. How can i connect checkbox to DataGridview. Example: Assume Each Checkbox have one subject. like English,Maths,Physics,Chemistry,Arts..... If i click English Checkbox then Corresponding Students list will show in the datagrid. when i checked Maths , corresponding students list will show in the Datagridview. How can build the code to develop this???
Interesting problem. I have a datagrid with several columns which are bound to an Access database. Here's the situation...I'm concerned with the 3rd column.This is what I'd like to happen... when the 3rd column(is a checkbox) is checked then column 4(TIME_USER) would be populated with the current time
Basically, this application is meant to keep track of tasks that the user has to do at a certain time of the day. When the user checks the checkbox it would record the time in the database for that task as to when they did it. I found some code from a forum that i changed to fit my needs, but it's not working.
I am working with windows application. I have a datagrid in vb.net. Its first column is a checkbox. I want to know which checkboxes are checked and which are not. My code is :
I have a datagrid, with an unbound checkbox column. How can I get a range select use shift and ctrl keys that will check the checkbox?The moment you check a box, it selects only that row, so the rows selected are down to just the row you clicked on. I've been playing with several events and settings and I can't seem to get it. Can anyone point me in the right direction?When your problem is solved, add (RESOLVED) to the end of your topic. This will save the guru's time and be able to solve more problems. Remove the question mark icon as well.
