Hi,
I am creating a webform thru xslt. There are no of textboxes and and reqfield validators , range validators etc inthe web form. All other controls are also working fine. All the validations for the requiredfield validator, range validator works fine.. Only the custom validator is not working .. OnServerValidate ="test" does not fire for the custom validator.
This is the xslt


<xsl:for-each select="validation/validator">
          <xsl:if test="@type='required'">
            <asp:RequiredFieldValidator ErrorMessage="{text}"  runat="server"
              ControlToValidate="{$current_id}" ForeColor="{forecolor}"  Display="{display}"/>
          </xsl:if>
          <xsl:if test="@type='compare'">
            <xsl:variable name="comparevalue">
              <asp:value-of select="valuetocompare" />
            </xsl:variable>
            <asp:CompareValidator ErrorMessage="{text}" runat="server"
              ControlToValidate="{$current_id}" ValueToCompare="{valuetocompare}" Operator="{operator}" ForeColor="{forecolor}"  Display="{display}"/>
          </xsl:if>
          <xsl:if test="@type='range'">
            <asp:RangeValidator ErrorMessage="{text}" runat="server"
              MaximumValue="{max}" MinimumValue="{min}" ControlToValidate="{$current_id}" Type="Integer"  ForeColor="{forecolor}"  Display="{display}"/>
          </xsl:if>
          <xsl:if test="@type='custom'" >
            <asp:CustomValidator  ErrorMessage="{text}" runat="server" ControlToValidate="{$current_id}" OnServerValidate="test1"   ForeColor="{forecolor}" ValidateEmptyText="True" EnableClientScript="False" />
          </xsl:if>
        </xsl:for-each>


I am checking page.validate on Page load

if (IsPostBack)
        {
            Page.Validate();
}

Could any help me find out what could be the reason the server side function is not working

Thanks
