Hai All,

        I am using fileupload inside Radgrid.I have several tabs in my page.but while using document upload page in the application,It is doing a postback.I would like to know about how to avoid this post back in my is the code which i used in my application:

 aspx page: 

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" ClientEvents-OnRequestStart="conditionalPostback"> 

 <telerik:RadProgressManager ID="RadProgressManager1" runat="server" />  




 <telerik:RadGrid ID="RGDocuments"   

<PagerStyle Mode="NextPrevAndNumeric" />  

<MasterTableView Width="100%" CommandItemDisplay="Top" DataKeyNames="PKID,DocumentType,DocumentName,UploadedTime,DocumentExpiryDateFlag,DocumentExpiryDate">  


<telerik:GridTemplateColumn HeaderButtonType="TextButton" UniqueName="Upload" HeaderText="File Name">  



<asp:Label runat="server" ID="lblFileName" Text='<%# Eval("FileName") %>' />     



<asp:FileUpload Width="400" BorderColor="AliceBlue" onclick="return Check()" ID="RadUpload1"  runat="server" />   







aspx.cs Code  


protected void RGDocuments_ItemDataBound(object sender, GridItemEventArgs e)  



FileUpload upload = (FileUpload)e.Item.FindControl("RadUpload1"); 

RadAjaxPanel1.ResponseScripts.Add(string.Format("window['UploadId'] = '{0}';", upload.ClientID));

Hello Imthiyas ,

To upload a file you need to postback. There is no workaround for the time being. Check this help article for additional info.
