asp.net webpage fails to load a C# windows control in it

Naveen Gowda9-Dec-07 22:08

i have a windows control which is to be loaded on a webpage(.aspx page)
control is loaded with the aid of "object" tag
the control is developed in C#.net(managed code basically)
the control makes use of the system resources and even makes use of some other dll's too

problem:
the control fails to load on the webpage

first solution tried:
change the .net security with the aid of caspol
so i tried giving full trust to all code
this worked fine and the control got loaded.

however this worked fine only when the webpage was a part of the default website in IIS
in case if the webpage which hosts the control is a part of a virtual website apart from the default website
the control is failing to load

so what might be the problem...??

from some of the blogs which i read...the .net tries to give trust
to assemblies based on from where the assembly is getting streamed
so i also tried to load the control by making this site a trusted one
still the control didn't load

any idea...as to might b wrong....

Hi! ALL
I done the report.
The solution of above problem is:
DataSet ds = GetDataset(); // generate dataset here.
DataTable dt = ds.Tables[0];
report.Load(Server.MapPath("report.rpt"));
report.SetDatabaseLogon("abc","xyz");
report.SetDataSource(dt);
CrystalReportViewer1.ReportSource= report;
CrystalReportViewer1.DataBind();
That's way i achieve the task.

To add to the answer you got, the reason you can't do this, and the reason you can't get at a file upload path in javascript, is security. While your use may be benign, imagine if someone could write a webpage, and make it so when you browsed it, any file that had a known path ( such as Windows files ) could be uploaded to a server ?

DataList Item Enumeration in ASP .NET 2.0

Hi there.

I'm having an issue with enumerating through the bound items in my DataList. It seems as though the Items property of the DataList control only contains the control that you add as an Item Template.

Is there anyway to enumerate through the DataList's BOUND items and convert it back to the original control type?

I've solved the problem.

The way to enumerate is:

For Each item As DataListItem In lstControlList
For Each ctl As Control In item.Controls
CType(ctl, MyControlObject).Property = Value
Next

Download File

Hi experts,
I need a linkbutton/button to download the files which my clients have uploaded.

Below is my upload method and it works.

protected void uploadFile()<br />
    {<br />
        String projectID = (String)Session["projId"];<br />
        //change the file name<br />
        if (!FileUpload.FileName.Equals(""))<br />
        {<br />
            // Create a new folder in Docs folder (folder name = projectID)<br />
            System.IO.Directory.CreateDirectory(Server.MapPath("Docs/") + projectID);<br />
<br />
            // Save the file into the new folder.<br />
            FileUpload.PostedFile.SaveAs(Server.MapPath("Docs/" + projectID + "/" + FileUpload.FileName));<br />
            lblFile.Text = FileUpload.FileName + " is uploaded!";<br />
            lblFile.Visible = true;<br />
<br />
        }<br />
    }//end of method

However, it's not working for downloading of file (in another asp)
May I know how can I do that?

protected void btnLink_OnClientClick(object sender, EventArgs e)<br />
{<br />
   String projectID = (String)Session["projId"];<br />
   String file1 = System.IO.Path.GetFileName(Server.MapPath("Docs/" + pid + "/"));<br />
}

The files format that are uploaded are not consistent. Usually it's excel, word or pdf format.

Please help. Thanks!

You need to set the header and then do a Response.BinaryWrite. You can also specify the filename, which will force a download. There's tons of examples on the web.

Where you are storing the file name ? Get the file name user need to be downloaded and do a Response.Redirect() to the file URL.

There is no built in tree view controller for ASP.NET 1.1. You can't use that control in ASP.NET 1.1, because it's .NET 2.0 compatible. You can write a custom control for ASP.NET 1.1.
