I have winform application I want to populate a radgrid view on basis of another radgridview. I want to do this by checking a checkbox column, If the checkbox is checked I want to add an item to other radgridview and if it is unchecked I want to remove that item.
I am trying to achieve is that when the checked state of a CheckBox in one CellValueChanged event.
Use RadGridView_ValueChanged event. In this event if you have just clicked on checkbox column than if checkbox is checked its values is on otherwise off
If you are looping throgh the checkbox column then for current row checkbox value would be on or off and for other rows its value will be true / false

I have a datagridview and recently I got task to add a checkbox column (which I did) and a button (btnFilter) that will filter/show only selected rows so for example if I check only 4th, 5th and 6th row and click on 'btnFilter' the datagridview would show only rows 4,5 and 6.
So, the problem is how to show only selected (checkbox) rows.
Thank you for your time.
The idea is to have a button which when clicked, a loop will be executed over GridView Rows. Within the loop we will check whether the CheckBox for that row is checked, if the CheckBox is checked then the Value from the GridView Row Cell and Cell controls like Label, TextBox, DropDownList, etc. can be fetched.
Here is the complete example with screenshots and source code in C# and VB
GridView checkbox: Get Selected rows
I have a Datagridview with first column as checkbox.I have created the checkboxcolumn at design itself.While updating the gridview according to the entries from database, I have to check and uncheck the checkbox programatically not all at a time but only a specific row.Please tell me how can I update check boxes programmatically.
You can bind the data from database directly to checkbox column if it is bit type in DB.
Do something like this
(row.Cells[CheckBoxColumn.Index] as DataGridViewCheckBoxCell).value = false;
During bind data you need to check it manually if flag is true then set it checked otherwise unchecked as like
set checkbox1.checked=true or false
Check datagrid prerender event, get reference to the checkbox and set value accordingly.
At the time of databinding use this code
CheckBox chkbx= e.Item.FindControl("CheckBox1") as CheckBox;
then you can manipulate chkbx.Checked to true or false based on your values
and similarly it can be used for rest of the checkboxes buttons
I have made a checkbox inside the header of checkbox column. It works fine when i check it all rows in the DataGridView gets checked. What I want to do is to uncheked the header cell checkbox when a single row in the DataGridView is unchecked. I tried putting code in the CellValueChanged event that sets the header checkbox state. The problem is that CellValueChanged is fired when current cell loses focus. So if I click two or three times in the cell nothing happens, but when e select next cell the event is fired and the header cell checkbox state is invalidated.
In CurrentCellDirtyStateChanged event call the datagridview's CommitEdit(DataGridViewErrorContexts.Commit) method.
It commits the cell value and triggers the CellValueChanged event of corresponding cell.
tried CurrentCellDirtyStateChanged event?
I am currently using a datagridview in C# that is working correctly.
This datagridview has a checkbox field thats linked too a database, I am requiring all rows in the datagridview to be red until the checkbox is checked. Once the checkbox is checked the row will then turn green.
I am also requiring the checkbox field to be the only field in the datagrid that is not read only, but this isnt crucial at this stage. I hope you can offer me some suggestions.
Using visual studio 2010 in a windows forms application
Refer to CellContentClick event.
Read the cell value when user clicks it. If the checkbox is set then get the row index from event handler and write the following line in event handler.
datagrid.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Green;
I create the checkbox column in datagrid. and it works fine. But i need to select or fire the click event to whole the checkbox column with another checkbox outside the datagrid.I tried it but it just checked the checkbox but it doesn't fire the click event within the cells containing the checkbox. SO is there any solution?please help
Loop through the grid and set the value as shown for the column concerned in the checked event of the other checkbox
foreach (DataGridViewRow var in dataGridView1.Rows)
{
var.Cells[3].Value = true;
}
