Hi Steve,
I created an example to show you how to do it:
-- beging aspx code --
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindData();
}
}
private void BindData()
{
dg.DataSource = new int[7];
dg.DataBind();
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
int index = dg.EditItemIndex;
if (index >= 0)
{
DataGridItem item = dg.Items[index];
RequiredFieldValidator validator = (RequiredFieldValidator)
item.FindControl("rfv");
TextBox textBox = (TextBox) item.FindControl("textBox1");
}
}
protected void dg_EditCommand(object source, DataGridCommandEventArgs e)
{
((DataGrid) source).EditItemIndex = e.Item.ItemIndex;
BindData();
}
</script>
<asp:DataGrid runat="server" ID="dg" AutoGenerateColumns="false"
OnEditCommand="dg_EditCommand">
<Columns>
<asp:TemplateColumn>
<ItemTemplate>
column1
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList runat="server" ID="ddl"
OnSelectedIndexChanged="DropDownList1_SelectedInde xChanged"
AutoPostBack="true">
<asp:ListItem Text="1" />
<asp:ListItem Text="2" />
<asp:ListItem Text="3" />
</asp:DropDownList>
</EditItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn>
<ItemTemplate>
column2
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="textbox1" runat="server">
</asp:TextBox>
<asp:RequiredFieldValidator ControlToValidate="textbox1" runat="server"
ID="rfv">
</asp:RequiredFieldValidator>
</EditItemTemplate>
</asp:TemplateColumn>
<asp:ButtonColumn CommandName="Edit" Text="Edit" />
</Columns>
</asp:DataGrid>
-- end aspx code --
hope this helps

Hi everyone,
I have a DataGrid with several TemplateColumns. One of these columns has an
EditItemTemplate that contains an ASP.Net DropDownList. I'm catching this
DropDownList's SelectedIndexChanged event.
I also have another TemplateColumn, with a RequiredFieldValidator that
validates a TextBox in the column. It all looks like this, in broad
strokes:
<TemplateColumn>
<EditItemTemplate>
<asp:DropDownList OnSelectedIndexChanged="some method">
</asp:DropDownList>
</EditItemTemplate>
</TemplateColumn>
<TemplateColumn>
<EditItemTemplate>
<asp:TextBox id="textbox1">
</asp:TextBox>
<asp:RequiredFieldValidator ControlToValidate="textbox1">
</asp:RequiredFieldValidator>
</EditItemTemplate>
</TemplateColumn>
When I'm in the method that catches the SelectedIndexChanged event, can I
somehow retrieve the RequiredFieldValidator and set its properties? I've
been noodling with FindControl() in various incarnations but haven't found
the right mix yet. Any help or snippets are appreciated.
Thanks!
