RadGrid Row + Multiple DropDownLists, where 2nd + 3rd's datasource are dependant on selected value of first dropdown.

[Neal]

Hi

I need to determine in the SelectedItemChange event of the first dropdownlist in a rad grid row, the parameters to pass to the 2nd and 3rd dropdownlists for them to  databind.
Note: This in insert mode (AddNew record) , and no Records loaded i.e.  Blank Table,...and trying to create the new record.

So, how do I reference these other dropdownlists per that Grid Row" .....I don't have the   GridEditableItem param in the drop downs param
Typically I woud expect something like
DropDownList  my1stDropDown = Grid1.EditedRow,FindCZontrol(1stDropDown) as DropDownList;
string SelVal = my1stDropDown .SelectedValue;

DropDownList  my2ndDropDown = Grid1.EditedRow,FindCZontrol(2ndDropDown) as DropDownList;
my2ndDropDown.DataSource = SomeDSource;
etc


TIA
Neal

Hello Neal,

You can try out the following code to access other dropdownlists in the InsertForm on the SelectedIndexChanged event of the one dropdownlist.
cs:

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        DropDownList ddList1 = (DropDownList)sender;
        GridEditFormInsertItem insertItem = (GridEditFormInsertItem)ddList1.NamingContainer;
        DropDownList ddList2 = (DropDownList)insertItem.FindControl("DropDownList2");
        //bind ddList2 to the data source with custom code here
        ...
    }

Thanks
Princy.

Hi Thanks Princy,

Will give it a go,...my worry was that this is, on the first i.e. to be created row whilst in "insert mode of the Grid"..null reference exceptions.

If any hassles will reply asap.
