    Hi All,
    I have a Grid with a BoundColumn that I would like to have the input as a multiline textbox, taking up the width of the grid (that is to the right of the edit form headings).
    See the attached picture to see what I mean.
    It seems that the Edit Form is not the width of the Grid, but much smaller (it's bounds are where the Textbox ends currently).
    I am trying to set the 100% width in the ItemDataBound event of the RadGrid by :
    TextBox tb = null;
    GridDataItem gdi = e.Item as GridDataItem;
    tb = (TextBox)gdi["Notes"].Controls[0];
    Is there another way to get this field to become wider?  Setting it to a pixel value works, but is not ideal.

    I tried setting the width of the Table and TableCell which contains the TextBox control in edit-form and got worked for me. Give a try with the following code and see whether it work for you.

    protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
        if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
            GridEditFormItem editItem = e.Item as GridEditFormItem;
            Table editTable = (editItem.EditFormCell as GridEditFormItem.EditFormTableCell).Controls[0].Controls[0] as Table;
            editTable.Width = Unit.Percentage(100);
            TextBox textBox = (TextBox)editItem["Notes"].Controls[0];
            textBox.TextMode = TextBoxMode.MultiLine;
            (textBox.Parent as TableCell).Width = Unit.Percentage(100);
            textBox.Width = Unit.Percentage(100);
    [I guess you are using AutoGenerated editform]

    Happy coding .. :)

    Awesome mate!
    Thanks Shinu - the table cell resize was what I was missing.

    Hi Orly,

    Practically you can access the controls of any Column, Template or Bound Columns, event automatically generated ones. Check out the article describing more about that: Accessing Cells and Rows

    There you will get a better idea how to access cells, controls if different types of columns. It may not cover all possible scenarios, but will give you a great idea from which you can improvise.

    Kind regards,
