Hi Richard,
We can change a Textbox to a DropDownList in Datagrid edit mode. Please see
the following steps:
1. Change the bound column to a template column. You can easily do this in
the properties builder of the Datagrid. Select the columns tab, and then
click the column in the "Select columns"listbox, and you will find a link
"convert this column to a template column" upon "OK" button. Click the link
then click OK.
2. Right click the Datagrid and move to "Edit Template", then select the
template column in the pop up menu, delete the textbox in the
EditItemTemplate cell and add a DropDownList.
3. In the code behind, initialize the DropDownList in the
DataGrid1_ItemDataBound event:
Here is a snippet:
private void DataGrid1_ItemDataBound(object sender,
System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if(e.Item.ItemType == ListItemType.EditItem)
{
Control ctrl=e.Item.FindControl("DropDownList1");
if(ctrl!=null)
{
DropDownList dropdown=(DropDownList)ctrl;
dropdown.DataSource =DataGrid1.DataSource ;
dropdown.DataTextField = "id";
dropdown.DataValueField = "value";
dropdown.DataBind ();
}
}
}
