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;

            }

        }
