Uploading even on postback

[hari prasad ananthuni]

Hello all,
        I'm using Rad upload control with rad progressarea and rad progress manager in a user control. 

 

 

<%

@ Control Language="C#" AutoEventWireup="true" Inherits="wucPreliminaryPlans" CodeBehind="wucPreliminaryPlans.ascx.cs" %>

 

<%

@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

 

 

<

 

table>

 

 

<tr>

 

 

<td>

 

 

<telerik:RadUpload ID="rdupload" runat="server" ControlObjectsVisibility="None"

 

 

MaxFileInputsCount="1"

 

 

OverwriteExistingFiles="false" TargetFolder="~/Uploads/MyFiles"

 

 

OnFileExists="rdupload_FileExists">

 

 

</telerik:RadUpload>

 

 

</td>

 

 

</tr>

 

 

<tr>

 

 

<td>

 

 

<asp:Button id="buttonSubmit" runat="server" OnClick="buttonSubmit_Click" text="Submit" />

 

 

<asp:Label ID="labelNoResults" runat="server" Visible="True">No uploaded files yet</asp:Label>

 

 

</td>

 

 

</tr>

 

 

 

<tr><td>

 

 

<telerik:RadProgressManager ID="rdUploadProgressManager" runat="server" />

 

 

<telerik:RadProgressArea ID="rdUploadProgress" runat="server" Language=""

 

 

ProgressIndicators="TotalProgressBar, TotalProgress, TotalProgressPercent, RequestSize, FilesCountBar, FilesCount, FilesCountPercent, SelectedFilesCount, TimeElapsed, TimeEstimated, TransferSpeed"

 

 

Skin="Vista" >

 

 

<Localization Uploaded="Uploaded"></Localization>

 

 

</telerik:RadProgressArea>

 

 

</td>

 

 

</tr>

 

 

 

</table>

 

Code behind.

 

 

protected

 

void Page_Load(object sender, EventArgs e)

 

{

 

if (!IsPostBack)

 

{

 

//Do not display SelectedFilesCount progress indicator.

 

 

 

 

 

rdUploadProgress.ProgressIndicators &= ~

ProgressIndicators.SelectedFilesCount;

 

}

}

 

protected

 

void buttonSubmit_Click(object sender, System.EventArgs e)

 

{

 

if (rdupload.UploadedFiles.Count>0)

 

{

labelNoResults.Text =

"Thanks for Uploading";

 

 

}

 

else

 

 

 

 

 

{

labelNoResults.Text =

"No files to upload";

 

}

}

 

it is working fine for even i click the upload btn.

But problem arises whenever my page is postback and if i have a value in the rad upload ,
it is uploading automatically.

Is there anyway to stop this.

Thanks,
Hari.

Hello hari prasad ananthuni,

The help article provided in the previous post should help you solve your problem. The idea is to clear the value of the fileinput if the postback was triggered by a button different than the upload one. The workaround works in a asp wizard  as well.

Hello,

I have the same problem accept I have 2 user controls on the page.  One with the upload control and its upload button and another that has a couple buttons that post back.  The buttons that post back in the second user control are causing an upload if there is a file selected.  Is there anyway to avoid this in my situation?

Any help is greatly appreciated.
Thank you,
Nick
