i've create a datagridview with two columns, one textbox and the other checkboxes. The chekcbox column has a check box in column header aswell.
When i resize each column the checkbox column speciallly the checkbox in the column header, does not align with the checkbox column, it even goes in the textbox column as well. How do i fix this column resize issue?
I want to create two columns of checkboxes but only the first column is being displayed.

I am using data grid view in Windows Form standalone application to display items as excel spread sheet in VB.NET. I got a table named CostTypes with column names [CostTypeID, CostType] and values [1,External] and [2,Internal] (These are constant but more values can be added to table).
I want to create columns with names of the values[External , Internal] in DataGridView. If I use databiding directly I get columns [CostTypeID,CostType] which is not what I am looking for.
I am trying to calculate two columns in a DataGridView. The first column is the points column and the second column is the Rental_charge column. I would like one text box to display the total of points and the second text box to display the total Rental_charge.

I'm working on a project where I've loaded a database into a DGV. I also have an additional unbound checkbox column for the users to select entries with. I have code in place to read the selected rows and save them into a CSV string, which is then saved in the usersettings. All this works fine.
PROBLEM AREA:
I'm trying to reverse this effect so that when the DGV loads, the checkboxes that the user selected previously are checked (and the others left unchecked). I've debugged this extensively, and using watches have confirmed that all the values in the loops are right, and the conditionals are all kicking correctly, but it seems the code I'm using to actually check the boxes doesn't work. I've searched dozens of web pages, msdn white papers, and forums, but no suggestions will check the darned box. Below is some example code.[CODE...]
In debugging, it seems the value for the Cells IS changed, but the checkbox never gets selected. The try/catch was just to pick any error messages (but there are none with this code). What am I doing wrong here?
I'm using datagridview in my vb.net project. In that datagridview I use checkbox for null value check property if the user click that how I check if the box is check or not in a number of rows and know how many check boxes are clicked also want to count. i try with my coding but it leaves the first line how I check.
Dim tableid As Integer
mydisp = New SqlDataAdapter("select max(id) from tst_m_tables", Myconnection)
mydisp.Fill(mydst, "id")
tableid = mydst.Tables("id").Rows(0).Item(tableid)
For i = 0 To dgvtabledetails.Rows.Count - 1

I have a datagridview that is showing Yes and No in 2 checkbox cells. (Logically I should have just one checkbox but it is a legacy program (from Excel VBA)). So what I want to do is if the user clicks one checkbox cell to make the value True then the other checkbox in the row needs to be set to False. I have googled and searched the Forums here for an answer for this but found nothing really specific. The envisaged problem here of course would be that the events are mutual so they should not keep firing continuously in a "loop" when one or the other is changed - that might be the really difficult bit.
View 5 Repliesi am currently having problems with Datagridview, for example when i select the first checkbox, second checkbox onwards.
I would like to update the textbox on my form to display '2' records selected. But there is one problem i faced is that when i deselect the checkbox, it does not update. It still display '2' record selected. What event handler should i use to get it to work?

I have a strange problem with a DataGridView I'm using which is bound to a table in VB.net
I've added a checkbox column to allow a user to tick a bunch of rows that I can then loop through and save off to a different table. All the checkboxes are enabled by default. So it's really a case of unchecking the rows which aren't required.
However, the DataGridView re-enables any checkbox that I click after I click on a checkbox in another row. So in effect, only one row can be unchecked at a time.
EDIT: I forgot to mention this is a Windows form, not an ASP.net application.
.Net 3.5
I have 2 columns in a datagridview bound to datasource. When the user checks off one checkbox, i want to check some business logic after which I set the 2nd check box in the same row as checked as well.
My problem is: I want to check the 2nd check box right after the user clicks on the first checkbox and not only after he tabs away by clicking somewhere else.
Right now, I only succeed runing my business logic in the CellValueChanged or CellParsing events but those only occur after the user leaves the checkbox, which is not desired, I d like to run the logic and show the 2nd checkbox checked right after the user clicks on the 1st checkbox.
I also tried: CellClick event but I don t know how to : when the user clicks on a a checkbox, how to change the value of other checkboxes in the current row during CellClick event . The changes does not take effect in the UI !!!

I am working with a datagridview and checkboxes. Ok, I have the following code which runs without any errors but doesnt give the required results.
1) My problem is that, when I uncheck the checkbox in Cell 2, I want Cell 9 and Cell 6 to be empty.
2) When I uncheck the checkbox in Cell 2 and click any other Cell in the datagridview and check again checkbox in Cell 2 - it DELETES the data in Cell 9 & 6.
Now, when I check again the checkbox in Cell 2, Data is not populated in Cell 9 & 6 regardless how many times I try....
[Code]...
I believe the following code, which clears/unchecks the checkbox in the "RowSelect" column, actually runs, but it runs VERY slowly. In testing I have approximately 2300 rows in my DataGridView:
Private Sub btnClearAll_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClearAll.Click
Dim curRowIndex As Integer = 0
Try
dgvWISDataGrid.SuspendLayout()
For curRowIndex = 0 To dgvWISDataGrid.RowCount - 1
[Code] .....
The app appears to "hang" because this loop is taking so much time. When I hit the pause button, it always seems to freeze on the "dgvCell.Value = False" statement and when I hover over it the popup says "Property evaluation failed." Something is taking quite a long time or is interfering with this routine.
I have a checkbox column in my grid. Let say the name on that column is "Cut". How should I do to take the right mouse button and and get a little menu where I can choose select all or deselect all checkboxes?

I am creating a program in Visual Basic 2008 and I would like it so when I check a check box, the word that corresponds with the check box (in the code) will show up in the text box. So if i had one check box that said, Hello. Whenever that check box was clicked the word, Hello, would show up in the Text box. And then if I checked another check box, Bye, the word Bye would show up right below Hello. So it would look something like this.
Hello
Bye
But whenever I unchecked the check for hello, the word hello would go away and Bye would move to the top of the text box.Here is the code that I have so far. I can make the words appear in the text box but not at the same time in the list.

View 2 RepliesOk so with my program i'm trying to create a save configuration I have it in my context menu so that I can click save configuration and what i want it to do is check to see what check boxes are checked and save those to a file (i.e. a notepad file or whatever works) that way I can save categories for customers or my own computer or whatever and than i'll just click load and choose the category I want and it will load the checkboxes that I want to install. I found a similar post but it's not really making sense to me. So i'm wondering what I need to do to make this work.
I'm also wondering how i'm going to load the configuration but I might have to wait on that one step at a time.
