Hiding GridEditCommandColumn

[The KID]

Does anyone know at what point the GridEditCommandColumn is rendered? I need to be able to hid the column on the page load given certain conditions and nothing that i've tried, i never can find the control. I can find other controls such as grid data item and template items, but not the GridEditCommandColumn items.

Thanks

Hello Mike,

According to what i understood,  the code snippet below  hides the GridEditCommandColumn on PageLoad.

CS:

protected void Page_Load(object sender, EventArgs e)
    {
        foreach (GridColumn column in RadGrid1.MasterTableView.RenderColumns)
        {
            if (column.ColumnType == "GridEditCommandColumn")
            {
                GridEditCommandColumn editcol = (GridEditCommandColumn)column;
                editcol.Display = false;
            }
        }
    }

Thanks
Princy.

Thanks for the help. Do you know what i'd need to do to also hide items in the CommandItemTemplate? What I'd doing in this project is some people i want to allow them to add/edit the grid and other i want to hide that ability. So i have columns to add/edit as well buttons in the CommandItemTemplate.

Thanks

Hi Mike,

You can hide the CommandItem in the code behind as shown below.

CS:

 RadGrid1.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.None;

Maybe I haven't explained myself correctly. I need to do on a row by row basis. One row i want to hide the button the next i want to show the button. Should I be trying in the ItemCreate event or the ItemDataBound?

This is what you need to do:

protected void rgMain_ItemDataBound(object source, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            ImageButton imgbtn = (ImageButton)item["EditColumn"].Controls[0];
            imgbtn.Visible = false;
        }
    }

Hello Mike,

Indeed, this is the correct approach. You may also consider moving the code in the PreRender event handler, and iterating through all the items in the grid (foreach gridDataItem dataItem in RadGrid1.MasterTableView.Items), since the ItemDataBound may not be called on each page cycle. Other than that, the inner code remains the same.

All the best,
