Hej everyone,

I have a repeater on my ASP.NET page where I am using a customValidator that is valid if two controls in the same RepeaterItem have some particular values.

I am doing only server side validation But CustomValidator validateServerside event is not being truggered even if I call Page.IsValid from C# code.

Please adnice as I am stuck.

Code is as below.
ASPX Page code:
 
<ItemTemplate>
        <td>
            <b><asp:label runat="server" id="lblRequired" Text="*" ></asp:label></b>
        </td>
        <td>
            <asp:Literal ID="litVarName" runat="server"></asp:Literal>
        </td>
        <td>
            <asp:TextBox ID="txtVarValue" runat="server"></asp:TextBox>
        </td>
        <td>
            <asp:Literal ID="ltrValidationComment" runat="server"></asp:Literal>
        </td>
        <td>
            <asp:CustomValidator runat="server" id="requiredVar" ControlToValidate="txtVarValue" OnServerValidate="cusCustom_ServerValidate" errormessage="Variable variable must be given" />
        </td>
        <asp:HiddenField ID="hidRegexExpression" runat="server" /> 
        <asp:HiddenField ID="hidCampaignVariableId" runat="server" /> 
    </ItemTemplate>
 
.cs File Code ... Note this is not being valled at all
 
protected void cusCustom_ServerValidate(object sender, ServerValidateEventArgs e) {
            // Cast the sender object to a CustomValidator
            CustomValidator vldCustomValidator = (CustomValidator)sender;
            // Find the RepeaterItem, this is the parent object of the CustomValidator
            RepeaterItem rptItem = (RepeaterItem)vldCustomValidator.Parent;
            // Now find the control in the RepeaterItem
            TextBox txtValue = rptItem.FindControl("txtVarValue") as TextBox;
            // something to return
 
            Label lblRequired = rptItem.FindControl("lblRequired") as Label;
            HiddenField hidRegexExpression = rptItem.FindControl("hidRegexExpression") as HiddenField;
 
            if(!String.IsNullOrEmpty(hidRegexExpression.Value)) {
                if(String.IsNullOrEmpty(txtValue.Text))
                    e.IsValid = false;
                else {
                    e.IsValid = true;
                }
            }
            else {
                e.IsValid = true;
            }
        }

The above is actually working Now. The problem was I had to set
ValidateEmptyText="true" and it was not being triggered bcz TextBox value for empty string.
