Answer 1

You can use RowDataBound event of the GridViewChild control to fill the drop down lists. To get the selected value of a drop down list u can say something like this:

DropDownList ddl = GridViewParent.GridViewChild.Rows[someRowIndex].Cells[someCellIndex].FindControl("DropDownlist1") as DropDownList;
string v = ddl.SelectedItem.Text;

I hope that was beneficial to u.

Hey,

Bind the child gridview with parent data:

<ItemTemplate>
   <GridView id="childGrid" .. DataSource='<%# Eval("Items") %>' ItemDataBound="child_itemdatabound">
<ItemTemplate>

And then proceed to bind the DDL in the itemdatabound event:

.. child_itemdatabound(..)
{
   DropDownList ddl = e.Row.FindControl("ddl") as DropDownList;
   if (ddl != null)
   {
      //Load from data source
      ddl.DataSource = dal.GetData();
      ddl.DataBind();

      //You can set the selected value here too; e.Row.DataItem represents the bound data object
   }
}

You can also get the selected value in the same way, as mentioned in the other post.
