RadGridviewExcelExporter errors on Citrix

Greetings all

I have a simple winform app that loads a RadGridView and optionally exports it to Excel. The app works fine in the Development environment and as a standalone exe. However, when the code is moved to Citrix, the invocation of the RadGridViewExporter.Export method triggers an Excel error: "an error occured and this feature is no longer functioning properly". Once this error dialog is clicked, the export happens successfully.

I understand from various searches that this is likely a config issue with the server and not a Telerik internal problem. My hope is that someone has hit this before and might suggest a work-around from the application side.

We are using VS2010, .Net 4.0, and Q2/2011 Radcontrols for Winforms.

Relevant code follows. Many thanks for any advice.

private void Export(String filepath)

{

//this.radButtonExport.Enabled = false;

exporter =

new RadGridViewExcelExporter();

BackgroundWorker worker = new BackgroundWorker();

worker.DoWork +=

new DoWorkEventHandler(DoWork);

worker.RunWorkerCompleted +=

new RunWorkerCompletedEventHandler(bg_RunWorkerCompleted);

worker.RunWorkerAsync(filepath);

exporter.Progress +=

new ProgressHandler(exportProgress);

radProgressBar1.Visible = true;

radProgressBar1.Text =

string.Format("Exporting to {0}", filepath);

radProgressBar1.Width = radGridView1.Width * 2/3;

}

private void DoWork(object sender, DoWorkEventArgs e)

{

exporter.Export(radGridView1, (

String)e.Argument, "script results");

}

PageView Page and Anchoring

Hello,

I have some strange effects when using Anchor Bottom / Anchor Right with Controls placed on a PageView Page. The Controls do not keep their positions correcty. Also, the Designer (VS2010) seems to garble up sometimes.
Anyone else having issues with this?

Regards
Erwin

radGridView1_CustomSorting event not firing

Hey everyone,

Title Correction: radGridView1_CustomGrouping event not firing

I am trying to implement the following example I have found in the Telerik forums to get custom month sorting to work. (Link) I tried setting the CustomDataOperation on the column as the example indicates. When I did that, the Intellisense description stated that the CustomDataOperation property was deprcated and to use EnableCustomGrouping, EnableCustomSorting, etc on the GridView instead.

I have set all of these properties to true, yet the radGridView1_CustomSorting event does not fire.

Why? What else is needed?

Calculated Column Value Issue

Hi All,

I'm having a strange problem which I can't seem to work out the reason for. I have a series of columns of which one is calculated. When I go to save the values (be it a new row or an update), the field which the calculated column is linked with does not get updated.

My code for creating the calculated column is as follows:

GridViewDecimalColumn col = new GridViewDecimalColumn();

col.Name = "Total";

col.HeaderText = "Total";

col.FormatString = "{0:c0}";

col.MaxWidth = 90;

col.MinWidth = 90;

col.Width = 90;

col.FieldName = "Total";

col.FormatInfo = CultureInfo.CreateSpecificCulture("en-GB");

radGridView1.Columns.Add(col);

radGridView1.Columns["Total"].Expression = "IsNull(Ink, 0) + IsNull(PB_Products, 0) + IsNull(Office_Supplies, 0) + IsNull(Freight, 0)";

radGridView1.Columns.Move(11, 9);
