Display Datagridview dynamically created chechboxvalue? c#
0
I want to check all/ only certain Checkboxes as checked.
I tried various versions from stackoverflow but none seem to work out.
The code is called directly after dynamically creating the datagrid as I only want to load the Data once. - Datagrid is created in my Form_Load
The value of the Checkboxes are changed but not displayed.
//This is how i create the Datagrid column - not question relevant
for (int kacnt = 1; kacnt <= Ei.Kaanzahl; kacnt++)
{
DataGridViewCheckBoxColumn Kachk = new DataGridViewCheckBoxColumn();
Kachk.HeaderText = "Kamera" + kacnt;
Kachk.Width = 70;
WarDataGridView.Columns.Add(Kachk);
}
// The code I actually have problems with - the display of the value
foreach (DataGridViewRow row in WarDataGridView.Rows)
{
for (int col = 1; col < WarDataGridView.ColumnCount; col++)
{
(WarDataGridView.Rows[row.Index].Cells[col] as DataGridViewCheckBoxCell).Value = true;}}

Can you also mention event or method, in which you are trying to update DataGridView source? You will need to refresh once datagridview source is being updated.. try following stackoverflow discussion,, stackoverflow.com/questions/7008361/…

What is the column index of the column you want to check? You are starting at index 1 which means you are skipping the first column (index 0). Also, if your checkbox column is hidden, you need to useWarDataGridView.Columns.Countin your for loop.WarDataGridView.ColumnCountonly returns displayed columns.

Are you using a datasource, i.e.WarDataGridView.DataSource = dataSource_dataTable? I've noticed the data isn't finished loading immediately after databinding. In that case you need aWarDataGridView.DataBindingCompleteevent, and set the columns from there. You also may need to set the particular column withKamerachk.TrueValue = trueandKamerachk .FalseValue = false
