Change Width Of GridBoundcolumn in PopUp Edit Mode

[Eric Turner]

I guess this is my stupid question week.  I have a Hierarchy Grid that has one detail grid.  That grid allows rows to be edited in PopUp Mode.  Before the PopUp is shown I want to increase the width of one of the gridboundcolumns that will appear on the PopUp..  I can get a handle to the field but cannot figure out how to change the width.  There is no width property available.  Code is posted below.  I have also tried the FindControl method used in other examples but cannot get a handle to it that way.  Can someone point me in the right direction?  Thanks

protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
        {

            if ("Detail".Equals(e.Item.OwnerTableView.Name))
            {
                GridBoundColumn packageColumn = (GridBoundColumn)e.Item.OwnerTableView.GetColumnSafe("PackageName") as GridBoundColumn;
                GridBoundColumn fileIdColumn = (GridBoundColumn)e.Item.OwnerTableView.GetColumnSafe("FileId") as GridBoundColumn;
                GridBoundColumn connectionStringColumn = (GridBoundColumn)e.Item.OwnerTableView.GetColumnSafe("ConnectionString") as GridBoundColumn;

                if (e.Item.IsInEditMode && e.Item is IGridInsertItem)
                {
                    (e.Item as GridEditableItem)["PackageName"].Enabled = true;
                }
                if ("InitInsert".Equals(e.CommandName))
                {
                    packageColumn.ReadOnly = false;
                    fileIdColumn.ReadOnly = false;
                    connectionStringColumn.ItemStyle.Width = Unit.Pixel(200); //THIS IS THE FIELD I WANT TO CHANGE THE WIDTH OF
                }
                else
                {
                    packageColumn.ReadOnly = true;
                    fileIdColumn.ReadOnly = true;
                }
            }
        }

Hello Eric,

You could access the TextBox control rendered in the Editform and set the width to required in ItemDataBound event as shown below.

CS:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
        {
            GridEditFormItem edititem = (GridEditFormItem)e.Item;
            TextBox txtBox = (TextBox)edititem["connectionString"].Controls[0];
            txtBox.Width = Unit.Pixel(200);     // Set the width here
        }
    }

Regards,
Shinu.

Thanks Shinu.  I was all around it but just couldn't get it right.  That worked great.

I tried that and it didn't work.
What am I missing?

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

       {

           if (e.Item is GridEditFormItem && e.Item.IsInEditMode)

           {

               GridEditFormItem edititem = (GridEditFormItem)e.Item;

               TextBox txtBox = (TextBox)edititem["Name"].Controls[0];

               txtBox.Width = Unit.Pixel(1400);     // Set the width here  

           }

       }

<telerik:GridBoundColumn DataField="Name" FilterControlAltText="Filter Name column" HeaderText="Name" SortExpression="Name" UniqueName="Name">
                    <ItemStyle Width="150px"/>
                    <HeaderStyle Width="150px" />
                </telerik:GridBoundColumn>

Hello,

Could you please share which EditFormType you are currently using?

Please check out the following topic which demonstrates how to access controls in edit/insert mode:
( Section Accessing controls in edit/insert mode )
http://www.telerik.com/help/aspnet-ajax/grid-accessing-cells-and-rows.html

I hope this will prove helpful.

Change 
if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
to
if (e.Item is GridEditableItem && e.Item.IsInEditMode)

Code will look like

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

       {

           if (e.Item is GridEditableItem && e.Item.IsInEditMode)

           {

               GridEditableItem edititem = (GridEditableItem)e.Item;

               TextBox txtBox = (TextBox)edititem["Name"].Controls[0];

               txtBox.Width = Unit.Pixel(1400);     // Set the width here  

           }

       }
