GridView checkbox as ReadOnly

[RobertTheProgrammer]

Hi folks,

I'm using ASP.NET with C# code behind. I've got a GridView on my page that has several checkbox fields that are bound to database fields. I want the checkboxes to be visible and editable during normal "EditItemTemplate". However during "ItemTemplate" display, I want it to be ReadOnly. In other words, unless the users are in edit mode, they cannot toggle the checkbox. Apparently checkboxes don't have a ReadOnly option. I've tried setting "Enabled" to false and it works, although it's too grayed-out for my tasted and I'd rather just set it to read only.

Any idea how to do this?

I've got the workaround working... I use the OnCheckedChanged event to call code behind that resets the checkbox to it's original value. It works, but it's cumbersome because of all the overhead of reloading the page.

If anyone has any better ideas...

You could set the checkbox's Enabled value to False...
or you could use JavaScript to do this....

Again you would do this in your RowDataBound event for your GridView...

Private Sub MyGridView_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GV_MyGridView.RowDataBound
        Dim cb As CheckBox
        If e.Row.RowType = DataControlRowType.DataRow Then
            cb = CType(e.Row.FindControl("MyCheckboxName"), CheckBox)
            If Not cb Is Nothing Then
                cb.Enabled = False
                'cb.Attributes.Add("onclick","javascript:document.getElementById('" + cbl.ClientID + "').checked=false;")
            End If
        End If
    End Sub

Cheers!

I've tried the Enabled=false attribute and it works well, but the checkbox is too grayed out. My background is gray and it makes the checkbox almost vanish. I'd much rather have a ReadOnly type of option so that clicking on the checkbox would simply do nothing, but it would look relatively normal.

There is no ReadOnly property on checkboxes...I'd suggest using the JavaScript solution then.

Another option would be to use an image that looked like a checkbox which you could display when you wanted it to be 'Read Only' rather than the checkbox itself.

Ah! The checkbox image is brilliant! I'll do that. Thanks!
