Hi Jagadeeswararao,

Please have a look into the following code I tried to achieve your scenario from C# code. As per the following code if the total upload size exceeds 100MB, then rest of the files wont get uploaded to the server and an alert is displayed to the user.

ASPX:

<telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" Skin="Silk" TargetFolder="~/Images/Img/"

OnClientFileUploading="OnClientFileUploading" AllowedFileExtensions=".jpg,.zip"

MultipleFileSelection="Automatic" UploadedFilesRendering="BelowFileInput"

OnFileUploaded="RadAsyncUpload1_FileUploaded">

</telerik:RadAsyncUpload>

<br />

<telerik:RadButton ID="RadButton1" runat="server" Text="Upload" OnClick="RadButton1_Click">

</telerik:RadButton>

<asp:HiddenField ID="HiddenField1" runat="server" />

C#:

const int MaxTotalBytes = 104857600;

Int64 UploadedBytes;

protected void RadAsyncUpload1_FileUploaded(object sender, Telerik.Web.UI.FileUploadedEventArgs e)

{

UploadedBytes += e.File.ContentLength;

if (UploadedBytes <= MaxTotalBytes)

{

string targetfolder = RadAsyncUpload1.TargetFolder;

e.File.SaveAs(Path.Combine(Server.MapPath(targetfolder), e.File.FileName));

}

else

{

e.IsValid = false;

UploadedBytes -= e.File.ContentLength;

HiddenField1.Value = HiddenField1.Value + e.File.FileName + ", ";

}

protected void RadButton1_Click(object sender, EventArgs e)

{

if (!String.IsNullOrEmpty(HiddenField1.Value))

{

Response.Write("<script>alert('" + HiddenField1.Value + "'+' not uploaded since total file size exceeds 100MB.')</script>");

}

HiddenField1.Value = "";

}

Hope this helps,
Shinu.
