Hi Guys,

I am using 3.7 wpf datagrid control. 

I have a bound datagrid control with four columns. First column is checkbox, 2nd is read only and 3rd & 4th are editable columns with textbox editor.

Now I want user to allow cell of 3rd & 4th columns only if checkbox is checked in first column. 

I don't want to user to start editing values in 3rd and 4th columns without selecting checkbox field.

Any idea? how can I achieve this? 

i tried implementing checkbox template and handling checkbox checked event as folllow:

 private void CheckBox_Checked(object sender, RoutedEventArgs e)

{

         DataRow dr = mygrid.GetContainerFromItem(mygrid.CurrentItem) as DataRow;

         if (dr != null)

{

Cell cel = dr.Cells[2];

if (cel != null)

{

cel.ReadOnly = false;

cel.BeginEdit();

}

}

}

 but I am getting below error as I kept columns read only

"An attempt was made to edit a read-only cell or the cell content is not bound using two way binding."

Thanks

 

 

 

 

 

 

 

Guys,

Any suggestion on problem listed above? 

 

Hi Hiren, This can be achieved by handling the PreviewMouseDown event on DataCell and checking if the current cell satisfies the needed conditions to be editable, if it is not, you can set e.handled to false on that cell which would disable the cell from going into edit mode. I attached a small sample that demonstrates how to achieve this.
