grab the dropdown list from the datagrid

something like

for each item in DataGrid1.Items
dim ddl as DropDownList = item.FindContro l("DropDownList 1")
ddl.selectedIte mIndex = MyIndexValue
next

remember to do it after databinding has been done, and not in Item_create

you can do it at Item_DataBound,
should work

Re: Setting the SelectedIndex of a DropDownList in a Datagrid

You need to find the ddl in the collection of controls.
So you do something like this.
DropDownList ddl = (DropDownList) e.Item.FindCont rol("lstID");

then select the correct item as required

Re: Setting the SelectedIndex of a DropDownList in a Datagrid

In the OnDataBound event for the grid.
Heres as example.
private void setDataBinding( object sender,
System.Web.UI.W ebControls.Data GridItemEventAr gs e)

{


ListItemType lit = e.Item.ItemType ;

if(lit == ListItemType.Ed itItem)

{

DataRowView drv = (DataRowView) e.Item.DataItem ;

DropDownList dll = (DropDownList) e.Item.FindCont rol("lstLaterab ility");

etc..

}

}
