I have a mixed DGV of bound fields and an unbound checkbox. The DGV uses an SQL statement with a Group By clause. I then populate the DGV via table adapter/DS. So, I have two issues, first I need to get the status from another table that has the value of 0 or 1 in a column and set that checkbox. The part number already loaded into a cell will link to this table. I cannot link this table directly to my Group By table because it would lose its logic. The second issue, is changing the checkbox and saving it both to this table and the DGV for display.
I'm confused at which events in the DGV will need to be fired to do these tasks?This code seems to work OK but seems to run a little slow. So, i'm wondering if my approach to this is incorrect.
Private Sub DGVAdviceSummary_CellValueNeeded(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellValueEventArgs) Handles DGVAdviceSummary.CellValueNeeded
Work = New ExampleWork()Here the Work is a withevents variable and I've used the handles clause for handling various events fired by the ExampleWork object. However the event handler will not get assigned till the constructor of the ExampleWork returns. Now how can I handle any events fired from the constructor? I can move the constructor logic out to a separate method and call it after the constructor has returned and thus handle all the fired events including events fired from constructor. However it doesn't look good
in a winform, in vb net,I have a list view with hoverselection set to true. I start a drag and drop operation when the mousedown event is fired, but it's fired only when i release the mouse button on the control or on the dropped control! is it a normal behavior?
I've been thinking about my options when it comes to events in vb.net.What I'd like to do is to track events that are fired in an application without explicitly declaring them with 'handles' sub. Here is a pseudo-[code]....
Yeah I know, not quite working, but is there any way of implementing something like this in vb.net? My end game is really to be able to monitor events fired in many objects from another object, isn't there a more maintainable way to do that then to add a special sub in each object that handles the event that I want to catch? I need some way to let one object handle events fired in other objects without a special sub, the AddHandler goes a long way, but I can't really use that dynamically like so:[code]....
I have a datagridview that completely updates anytime changes are made to it. It is not connected to a source but rather the datagrid is filled when first launched.
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
I have some DataGridView code written in vb.net. (Nothing is attached to a datasource.)The 4th column is a checkbox cell.How do I detect if that checkBox is checked or unchecked?This code strangely reports TRUE or FALSE at random times. It even turns ON the checkbox in rows other than the row I clicked in. (Huh?)
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick Dim whichGrid As DataGridView = CType(sender, DataGridView)
[code].....
I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.
I have a form called LeaseAbstract; within the form I have two tabs: 'General' and 'Responsibility List'. In the General tab there is a checkbox called 'OutsideLease'. What I want is when the Outside Lease checkbox is checked the Repsonsibility tab becomes enabled and visible. I don't want that tab visible unless that checkbox is checked.
My code looks like this: Private Sub ckbOutsideLease_CheckedChanged(ByVal sender As System.Object, [Code] .....
This portion of code is in the code behind the LeaseAbstract form, I've tested it and it doesn't work.
I need to change the cell type of an unbound datagridview ROW to checkbox type at runtime. Optionally adding a row of all checkboxes or changing the default type to checkbox is also fine. I see many examples for setting a column type to checkbox but I don't see anything that operates at the row level. Even operating at the cell level would be fine.
I have the code below which works fine when checkbox at Cell 2 is Checked ie., the date is inserted in Cell 9. Now, when I unclick Cell 2 I want the Cell 9 to be cleared. Presently, it is not cleared after unchecking. The code highlighted in Red is the area I reckon I have a problem...
Code: Private Sub DgvReturns_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DgvReturns.CellClick If e.ColumnIndex = 2 Then
i want to know how to perform some action when i check the checkedbox in the datagridview ? if like, when i check this>> i will bring some data to another DGV, on the other way of saying is just add a new row into another DGV.
same goes to when unchecked the checkedbox >> i want to remove the row based on the checkbox in that specific row that i unchecked .
i used the method [datagridview_CellContentClick] and [datagridview_CellEndEdit] before.. for add new row into datagridview-SUCCESS but when i want to remove the specific row, -FAIL to do. that.
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 have a datagridview (unbound). Fields are Name, Family Name and Phone No and a checkbox colum.There are ten rows in that DataGridView. There is an OK buttonI need to get message of showing which rows user has checked. The message should appear when user clicks OK button.I am not able to get this message. I tried following code in OK button
Dim strCB As String = dgvChooseQs.Rows(0).Cells(3).Value.ToString
this code which supposedly updates myTable when the check mark is preset on a datagridview.The latter has a checkbox (a bit in myTable) in column 5.The code works but only updates one row no matter how many check are in the column.
I need to find out the order of events that are fired when a Row is updated in a DataGridView control. I have looked just about everywhere and cannot find this simple information.
I'm using a DGV to show some data & I'm using the CellClick event to run some code when the user clicks on each row. But I also want to run some other code if the user double clicks a row, but the CellDoubleClick event never fires, the CellClick event just fires twice. Does anyone have any ideas on how to make both events work?
I have a checkbox column in the datagridview and also a column named "partqty" which displays the quantity of materails available.. I would want that when the user checks on the checkbox, the quantities of checked rows should be added and displayed in the textbox..
I tired something like this.. But it displays 0(zero) in the textbox.Private Sub button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button1.Click
I just want to know on how will I add a Checkbox in each row of my datagridview. First I used a datatable to get all the values from my database and then pass it all to the datagridview. What I want to happen is at the first column of my datagridview there is the checkbox.[code]
I've created a Datagridview bound to a Datatable. This Datatable is updated by a event to reflect statistical information as it changes (sub second resolution). I have a checkbox to determine if a row is available for other functions and can be toggled on and off normally if my eventhandler is not receiving my updates.
If my bound Datatable is changed, the checkbox returns to its previous state as soon as the cursor or focus leaves the checkbox glyph (not the cell).
How do I toggle the checkboxes without them reseting without disconnecting my eventhandler?

There is an OK button
I need to get message of showing which rows user has checked. The message should appear when user clicks OK button. There could be several message, checking each row one by one, in a loop.
I am not able to get this message. I tried following code in OK button
Dim strCB As String = dgvChooseQs.Rows(0).Cells(3).Value.ToString
Cell(3) is my checkbox. Donot consider Rows(0), at the moment I am just checking value at row 0
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 created a Datagridview by dropping in from the Datasource. After I changed one column to be a Checkboxcolumn but it does not represent the values. In the table (smallint) I have 0s and -1s but it doesnt matter what I enter as True and False Value in the column it just shows that the box is checked.
I have a DataGridView that collects all kinds of data from my database. This data is then summed up and grouped by name...
I would like to add a column of chckboxes in the front of my DataGridView that does not control anything. This way I have a DataGridView that combines all sorts of info grouped up, and the user may then check the checkbox infront of the spesific data he wants to print.
I have a Datagrdiview control that is populated from values in a table. ie: One column would have a check box for weather a record has been processed using a Posted field as a boolean Check box. My problem as that I need this field to also show the results if the record is rejected or not. [B]I am trying to have the box unchecked if the record has not been posted. Checked if the record has been posted Or be Marked with a red X if the record has been rejected.The rejected field is of course in another column in the table.
I am using Visual Studio 2008, Vb .Net 3.5 and MS Access 2003.I have a datagridview (DGV) control bound to this MS Access DB. One of the queries is bound to this grid. Everything works fine, the data is displayed correctly. Here's the problem The SELECT statement of query has a BOOLEAN column which is shown as a check box on the grid (this is exactly what I wanted to be shown), when user clicks one of the check boxes all the records are updated. For example, if 30 rows are displayed and user changes stuats column from FALSE to TRUE for only 2 records all records in the table are set to TRUE.I have set the UPDATE command for this query's table adapter using the DataSet designer as "UPDATE <table> SET Status=?"
Can you please help me resolve this. All that I want is only those rows should be updated which are changed on the grid. Below is my code
