DataGridView read only cells

Question

I have a binded DataGridView that contains a large amount of data. The problem is that some cells has to be ReadOnly and also when the user navigates with TAB or ENTER betwe

Answer 1

I haven't tried this.

But, you could set the cell's readonly property to true (as per Rashmi), on RowEnter event?

I guess RowEnter event should fire when you move from one row to the other (or it should when you change from cell A1 to B3).

Does that help at all?

Answer 2

I iterated through the datagrid with the following code:

dataGridViewTest.DataSource = persons;

foreach (DataGridViewRow row in dataGridViewTest.Rows)
{
    foreach (DataGridViewCell cell in row.Cells)
    {
        if (cell.Value.ToString() == "John")
        {
            cell.ReadOnly = true;
        }
    }
}

Could you not use a template column instead of a bound column then have a condition for the readonlyness of the field?

Then you could present a label for readonly and a textbox for editable. Labels would not interfere with your tab index.

<asp:TemplateColumn>
  <ItemTemplate>
<%
    if ( <%# Eval( "ReadOnlyFlag" ) %> )
    { 
%>
    <asp:Label Text="<%# Eval( "BoundColumn" ) %>" />
<%
    }
    else
    {
 %>
    <asp:Textbox Text="<%# Eval( "BoundColumn" ) %>" />
<%
    }
%>
    </ItemTemplate>
</asp:TemplateColumn>
