I have several Rad Controls on a Web form including a RadComboBox that initially works correctly.  After clicking a button to export data to an excel spreadsheet the RadComboBox quits responding.  Clicking the arrow to dropdown the list does nothing while all other controls appear to work just fine.

The code I am useing for the expot is as follows:

            DataView detailDT = (DataView)detailGridView.DataSource;

            string filename = String.Format("{0}.csv", "ExportDetails");

            Response.Clear();
            Response.AddHeader("Content-Disposition", "attachment;filename=" + filename);
            Response.Charset = "";
            Response.ContentType = "application/vnd.xls";

            StringWriter stringWriter = new StringWriter();
            ArrayList colHeaders = new ArrayList();
            ArrayList dataRow = new ArrayList();

            //handle forcing Excel from treating file as an "sylk" file
            stringWriter.Write("  ");

            foreach (DataControlField dataCol in detailGridView.Columns)
            {
                colHeaders.Add(dataCol.HeaderText);
            }

            stringWriter.WriteLine(string.Join(",", (string[])colHeaders.ToArray(typeof(string))));

            foreach (DataRow dr in detailDT.Table.Rows)
            {
                foreach (DataColumn dataCol in detailDT.Table.Columns)
                {
                    dataRow.Add(dr[dataCol]);
                }

                stringWriter.WriteLine(string.Join(",", (string[])dataRow.ToArray(typeof(string))));

                dataRow.Clear();
            }

            Response.Write(stringWriter.ToString());
            Response.End();


Thanks

Hi

I've spent several days trying to recreate the "Grid / Hierarchy with Templates" demo at http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx from the example code, but I just can't get it to work. Is there a tutorial covering these tasks available that can show me a more step by step approach?

TIA

Hello,

We are using the the sample code from the demo: http://demos.telerik.com/aspnet-ajax/grid/examples/programming/draganddrop/defaultcs.aspx

The drag and drop is working for us.  However the loading panel only shows up for the first drag/drop in Firefox.  (same issue exists on your demo page as well.)  It works correctly on google-chrome.

Can someone advise as we can resolve this issue?

Thanks,

Hi there,
     I can't seem to see any event that is raised when the Cancel button is pressed on the RadProgressArea.  How can I perform a ClientSide action when the Cancel button in the RadProgressArea is pressed?

Regards,

        Scott.

I'm trying to use the ComboBox to allow a user to pick a shipping method based on their address.  I am populating the ComboBox's context with address information on the page using the OnClientItemsRequesting event, and then calling a server side OnItemsRequested event.  This works the first time, but has inconsistent behavior every time after that.  Since the user can change their address on the page, the shipping costs might need to be recalculated after the initial ItemsRequested event.  However, the event will not fire unless I select the text and clear it out.  I want the ItemsRequested event to fire every time the dropdown is opened (is caching possible in this situation in case they just want to change their shipping method without changing their address?).  Also, it would be great if the textbox could be disabled, since there is no real purpose for it.  I'll post a code example if necessary.

Thanks.

The following piece of code does not render properly in Internet Explorer, but it works fine in Firefox. I have attached the screenshots IEPanelBar.jpg and FirefoxPanelBar.jpg.  I would like to have the first Panel Item Expanded and the second Panel Item collapsed as shown in the screenshot FirefoxPanelBar.jpg. I would like to have the second PanelItem collapsed by default as show in the screenshot FirefoxPanelBar.jpg. Please let me know of any fix for this issue.

Thanks

hiya,

 

I’m using the binaryImage column in the samples:

http://demos.telerik.com/aspnet-ajax/controls/examples/integration/raduploadinajaxifiedgrid/defaultcs.aspx?product=grid

When the user edits a row, the “image name”, and “description” are correctly assigned.

 

However, the “Image” GridBinaryImageColumn contains nothing…This is counter intuitive.

How can I assign the current value to this GridBinaryImageColumn, so that the user can save the record without having to manually browse for the image?

 

Many thanks,

 

yogi
