Hi Experts,

Show the aspx of the button that you are clicking that is not firing the validation.

shafik_shafik_shafik 8-Mar-16 13:45pm

Thank You Ryan for your reply. I added the button click and edit the code but still it is not working. Please look at my below edited code:

<tr id="trReportAgency" runat="server">
<td class="fieldlabel">
<asp:Label ID="lblAgency" runat="server" Text="Agency:">
</td>
<td>
<asp:DropDownList ID="ddlAgency" runat="server" CssClass="listbox" Width="138px" OnClick="btnPrint_Click"/>
<asp:RequiredFieldValidator ID="rqAgency" runat="server" ControlToValidate="ddlAgency"
CssClass="validatorIndicator" Display="Dynamic" ErrorMessage="Please select agency."
InitialValue="-1" Text="i" ToolTip="Please select agency.">

</td>
</tr>

Please advise.

Hi Parveen,

Solution 2

If we make "CausesValidation" property is "true" then it is working.

ASP.NET

<asp:Button ID="btnPrint" runat="server" CausesValidation="true" Text="Print" OnClick="btnPrint_Click" />

Solution 3

CausesValidation default value is true. If you make this false then you forcefully saying that you do not want validation to fire.

Reference:
Button.CausesValidation Property (System.Web.UI.WebControls)[^]
