[Solved] Setting Column to visible having no effect

[Ilija]

Hi Guys,

I am setting a RadGrid column's visibility to false on a toolbar button press, and then back to true again when they press it again(a toggle). The problem I am having is that when I toggle the column invisible, it doesn't become visible again on the next toggle. I am just setting the Visible property of the column and I'm not sure why this is happening.

Here's what's going on in the code on the button click event:

	else if (e.Item.Value.Substring(0, 2).Equals("CC"))
	{
	bool hide = true;
	string[] colDel = e.Item.Value.Split(delimiterChars);
	string colName = colDel[1];
	RadToolBarButton mybut = (RadToolBarButton)e.Item;
	if (mybut.Checked)
	{
	mybut.Checked = false;
	mybut.ImageUrl = "";
	hide = true;
	}
	else
	{
	mybut.Checked = true;
	mybut.ImageUrl = "/Images/Toolbar/update.gif";
	hide = false;
	}
	foreach (GridColumn rc in rgAcct.MasterTableView.Columns)
	{
	if (rc.HeaderText.Equals(colName))
	{
	if (hide)
	{ rc.Visible = false; }
	else
	{ rc.Visible = true; }
	break;
	}
	}
	foreach (GridColumn rc in rgAcct.MasterTableView.AutoGeneratedColumns)
	{
	if (rc.HeaderText.Equals(colName))
	{
	if (hide)
	{ rc.Visible = false; }
	else
	{ rc.Visible = true; }
	break;
	}
	}
	}

The visibility setting part looks ok.  Without knowing what you have already tried, my suggestion would be to test whether mybut.Checked ever returns false.  I'd suspect that it is always returning the default true condition and not persisting the false setting once your code is finished executing.

Hello Ilija,

You can try the following code snippet to toggle the visibility of a column on button click.

cs:

protected void RadToolBar1_ButtonClick(object sender, RadToolBarEventArgs e)
    {
        RadGrid1.MasterTableView.GetColumn("ColumnUniqueName").Visible = !(RadGrid1.MasterTableView.GetColumn("ColumnUniqueName").Visible);
        RadGrid1.Rebind();

    }

Thanks
Princy.
