Dear members;

I want to use "asp:fileupload" and "asp:button" in my module. But after, I install the module and click upload button  I recieve below error:

Message: DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at ArianSQL.Control1.OnUploadClick(Object sender, EventArgs e) at System.Web.UI.WebControls.LinkButton.OnClick(EventArgs e) at System.Web.UI.WebControls.LinkButton.RaisePostBackEvent(String eventArgument) at System.Web.UI.WebControls.LinkButton.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace --- 

for resolve this Error, I use "dnn:urlcontrol.ascx"  fileupload instead of the "asp:fileupload". But I can't access file id, file name and file content after uploading the file.

Please help me that how solve this error.

Thanks in advance.

I resolved my problem:


 <asp:UpdatePanel runat="server" id="UpdatePanel1">
<asp:FileUpload runat="server" id="uplSqlScript" />
<asp:Button runat="server" id="btnSubmit" Text="Upload"
onclick="btnSubmit_Click" resourcekey="cmdUpload" EnableViewState="False" CssClass="dnnSecondaryAction" />
<asp:postbacktrigger ControlID="btnSubmit" />

And C# Sourec Code:

protected void btnSubmit_Click(object sender, EventArgs e)
if (Page.IsPostBack)
if (uplSqlScript.HasFile)
if (!String.IsNullOrEmpty(uplSqlScript.PostedFile.FileName))
var scriptFile = new StreamReader(uplSqlScript.PostedFile.InputStream);
txtQuery.Text = scriptFile.ReadToEnd();
