[Solved] About Operations with MS DropDownList in EditItemTemplate of GridTemplateColumn

[Dao]

After clicking edit, the data in the label does not show on RadGrid.
Select SelectIndex?

 DropDownList list = item.FindControl("List1") as DropDownList;
           list.DataSource = Country_values;
           list.DataBind();
           list.SelectedIndex = ?????; <<<Here

Pls

Hi Dao,

When using dropdownlist in EditItemTemplate, you can save the selected value in a Session variable and then set that value for the label in ItemTemplate. The same Session variable can be used to select the default item in the dropdown control on subsequent editing.

In the above post I saw that you are setting the SelectedIndex instead of SelectedValue. Can you try setting selectedValue to the session variable value and see whether it is working fine?

CS:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem item = e.Item as GridEditableItem;
        // access/modify the edit item template settings here
        DropDownList list = item.FindControl("List1") as DropDownList;
        list.DataSource = Country_values;
        list.DataBind();
        if (Session["updatedValue"] != null)
        {
            list.SelectedValue = Session["updatedValue"].ToString();
        }
    }
    . . .
}
protected void RadGrid1_UpdateCommand(object source, GridCommandEventArgs e)
{
    GridEditableItem editedItem = e.Item as GridEditableItem;
    DropDownList list = editedItem.FindControl("List1") as DropDownList;
    Session["updatedValue"] = list.SelectedValue;
}

Thanks,
Shinu.
