Hai there!

I've build a web user control which contains a repeater control. This
repeater control has several textboxes which need to be validated. The
repeater is bound to a dataset that contains a datatable with empty rows.

The validation I need is to check whether a value has been provided (like
Required). So, if the datatable has 3 rows, then the repeater shows also 3
item rows each containing the textboxes.

How to do the validation on the textboxes?

Thanxxxxx...

Hi,

just place a RequiredFieldValidator inside the same ItemTemplate where
TextBox to be validated is located (and give it the ID of the TextBox to
ControlToValidate attribute).

<%-- repeater item starts here --%>
<ItemTemplate>
<asp:TextBox ID="txtInrepeater" runat="server" />
<asp:RequiredFieldValidator ControlToValidate="txtInrepeater"
runat="server" ErrorMessage="Input
required!">*</asp:RequiredFieldValidator>
</ItemTemplate>
<%-- repeater item ends here --%>

This way every TextBox created by binding the repeater aso ahs associated
RequiredFieldValidator which means that input must be provided for each of
them.
