Hi,

In my application I have two buttons(submit and cancel)
Submit button validates and upload into database.
Cancel button will redirect to another page.

I want to achieve validation only for Submit button.
But validation is happening for cancel button also.

I dont want to do this. Please help me to achieve.

In your Cancel button (html part), include the following

CausesValidation="False"

Thanks. It's working fine. One more help please.
I have a html control to browse, on the same file.

<input type="file" id="filename" runat="server" name="filename" size="50" required />

Here, when I press Cancel button it's showing validation error msg. How to achieve this
using asp.net in
<asp:Button ID="btnCancel" runat="server" Text="Cancel" CausesValidation="false" CssClass="cancel-button" onclick="btnCancel_Click" />

Why aren't you using a FileUpload control?
<asp:FileUpload ID="FileUpload1" runat="server" />

Dear if you want to use asp file upload control than you can use regular expression along with that to restrict user for specific type of files...If you need further help.
You should post this as new quick question to get the answer.

Thanks buddy. I got my requirement using regular expression.

VICK 7-Oct-13 7:20am

Gud to hear that ur prblm got solved..

srmohanr 7-Oct-13 6:05am

Yes I can use. But I want to restrict users to select specific file types. For that I need to call a js function. I dont know how to do this in FileUploader control.
<input type="file" id="filename" runat="server" name="filename" size="50" required önchange="return Checkfiles();" />

function Checkfiles() {
var fup = document.getElementById('filename');
var fileName = fup.value;
var ext = fileName.substring(fileName.lastIndexOf('.') + 1);
if (ext == "gif" || ext == "GIF" || ext == "JPEG" || ext == "jpeg" || ext == "jpg" || ext == "JPG" || ext == "doc") {
return true;
}
else {
alert("Upload Gif or Jpg images only");
fup.focus();
return false;
}
}

You can still use the same javascript on the fileupload control.

srmohanr 7-Oct-13 6:09am

But I dont have OnClick or OnClientClick function in FileUploader. Please tell me how to do this

Ryan Zahra 7-Oct-13 6:11am

Ok then, what about doing it server side, through ajax?

srmohanr 7-Oct-13 6:12am

Can you please give me any example for this

Ryan Zahra 7-Oct-13 6:15am

You should search for ajax in asp.net...there are loads of tutorials online

VICK 7-Oct-13 6:38am

onclick OR onclientclick for JavaScript, does not show some time while working in Visual Studio,,, but we can use them in the same way as we used them in html controls (input type)...
