Different template for insert and edit

[saravanan k]

hi all,

I am new to telerik rad controls. i have a rad grid and a griddropdowncolumn in it. my requirement is i want this griddropdowncolumn as editable when i try to insert a new record. and the same column as readonly when i try to edit the record. i dont even know how to differentiate the insertmode and the editmode. kindly help me, by telling which handler to write the logic and also giving a small code snippet.

Regards,

Hello Saravanan,

You can differentiate insert/edit mode by checking e.CommandName inside ItemCommand event.Try the following code:

C#:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.EditCommandName)
    {
        (RadGrid1.MasterTableView.GetColumn("GridDropDownColumn1") as GridDropDownColumn).ReadOnly = true;
    }
    else if (e.CommandName == RadGrid.InitInsertCommandName)
    {
        (RadGrid1.MasterTableView.GetColumn("GridDropDownColumn1") as GridDropDownColumn).ReadOnly = false;
    }
}

thanks a lot for the response. the solution worked. i have one more problem. i need to append an empty list item in the drop down. i tried the option enableemptylistitem = true and gave an empty list item. but it is not coming once the drop down is databound. is there any option like appenddatabounditems = true for this column?. kindly help..

Hello,

For achieving this, you can access the drop down control and insert empty item inside ItemDataBound event as shown below.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
if (e.Item is GridEditableItem && e.Item.IsInEditMode)
{

   DropDownList dropDownList =  (DropDownList)editedItem["GridDropDownColumn1"].Controls[0];
    dropDownList.Items.Insert(0, new ListItem(" ", " "));
}

this snippet is not working. the error is "the editeditem doesnot exists in the current context". do i have to include any reference?

Hi,

'editeditem' is of type GridEditableItem. you can get it from e.Item while grid is in edit mode. Try the following code.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
if (e.Item is GridEditableItem && e.Item.IsInEditMode)
{
    GridEditableItem editedItem = e.Item as GridEditableItem;
    DropDownList dropDownList = (DropDownList)editedItem["GridDropDownColumn1"].Controls[0];
    dropDownList.Items.Insert(0, new ListItem(" ", " "));

}

Thanks
