Here is the detail description of my problem...

Sid.Mup 29-Apr-11 14:26pm

I am using some compare, required field validator and want to show the validation message in alert window. So I thought of using ShowMessageBox="true" in validationsummary. Message box is coming fine.
Later on I had to add a OnClientClick="javascript:return alertSid();" .
When I added this OnClientClick event my message box is not coming but validation is happening.
If I remove the OnClientClick event then again the message box is coming with validation summary message.

I even removed the whole code in javascript function just to check whether its because of some code mistake in java script. Even though its not coming.

Here is the code im using:

Name: <asp:TextBox runat="server" ID="txtName" ></asp:TextBox>

<asp:RequiredFieldValidator EnableClientScript="true" ID="rfvForName" runat="server" ControlToValidate="txtName"
Text="*" ErrorMessage="Please Enter Name"></asp:RequiredFieldValidator>

<asp:Button ID="btnOpenAlert" runat="server" Text="Alert" OnClientClick="javascript:return alertSid();" />

<asp:ValidationSummary ID="ValidationSummary1" runat="server" EnableClientScript="true" HeaderText="Error For the following"
DisplayMode="BulletList" ShowSummary="false" ShowMessageBox="true" />

Javascript:

function alertSid() {
return true;
}

Hi Sid.Mup,

replace
OnClientClick="javascript:return alertSid();"

with
OnClientClick="javascript: alertSid();"

the return statement is not allowing next function to execute.

FYI: the html generated for your button will be like this:

XML

<input type="submit" name="btnOpenAlert" value="Alert" onclick="javascript: return alertSid(); ;WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;btnOpenAlert&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, false))" id="btnOpenAlert" />

The WebForm_DoPostBackWithOptions function is added by Asp.Net and the return statement of your function is not allowing it to execute hence to validation summary message.

Hope this will help.

Thanks,
Hemant
