Question

I have GridView with 2 columns.

The first column is: test-label (TemplateField)

The second: checkbox (asp:CheckBoxField) that connect to sql table with bit column (done).

I want that on page load – the page will check every row, where the checkbox = true, the test-label.visble will be false.

I know how to write code with SELECT statement to check the value from the SQL table, but don’t know how to check every row on the gridview on the page-load.

how can I do that?

(i can’t use findcontroll for the checkbox because it’s checkboxfield and not just “checkbox”.

<asp:CheckBoxField DataField="done" SortExpression="done" HeaderText="done?" /> 

so, what can I do here? maybe to replace that field with regular cb? (i don’t know how to do there databind – on the regular cb).

Answer 1

you can use GridView.RowDataBound Event

so you can do something like

 protected void GVRowDataBound(object sender, GridViewRowEventArgs e)
        {
            var check = (CheckBox) e.Row.FindControl("ID"); // ID is id of the checkbox
            var lable = (Label) e.Row.FindControl("LableID");
            if(check != null && lable != null)
            {
                if(check.Checked)
                {
                    lable.Visible = false;
                }
            }
         }
