i'm cascading dropdownbox (radcombobox) with clientdatasource but i'm a having challenges when changing the main combobox in hopes of having oncustomparameter to fire again.

ComboBox

Loading items into RcbSubF after selecting the a value RcbFun for the first time is not a problem. The issues lies in selecting another value in RcbFun. The OnCustomParameter event "ParamMap" will not fire again. Any suggestion? 

Please be advised that these controls are in side a RadPanelBar.

I am currently hiding several gridbound columns on load by setting Display="False".

User can display/hide columns using the column header context menu.

All works fine accept that when a user maximizes the browser window all the hidden columns are displayed. 

It doesn't happen every time, though most times.

Tested with same issue on Edge and Firefox.

Any help would be greatly appreciated.

I have a telerik RadGrid. I have applied Manual CRUD operations in it. I am using In-Place editing mode. The problem is, when I am trying to Insert or Update the records, i am getting null values by this method 

Same thing happening in both RadGrid_UpdateCommand and ​RadGrid_​InsertCommand. 

Following is my ASPX code

Hi,

I have a rad button in a rad window, with both client click and on server event. the page in which the rad window is there has a radajaxmanager and a rad grid. The server event handles the export of radgrid data to an excel, this is an ajax request. I do not want to use the gridexporting. The following code exports the file:

 using (ClosedXML.Excel.XLWorkbook wb = new ClosedXML.Excel.XLWorkbook())
        {
            var worksheet = wb.Worksheets.Add(datatable, fileName);
            worksheet.Tables.First().ShowAutoFilter = false;
            worksheet.Tables.First().Theme = ClosedXML.Excel.XLTableTheme.None;

httpContext.Response.Clear();
            httpContext.Response.Buffer = true;
            httpContext.Response.Charset = Encoding.UTF8.WebName;
            httpContext.Response.AddHeader("content-disposition", string.Format("{0}{1}", "attachment;filename=", fileName));
            httpContext.Response.ContentType = contentType;

using (System.IO.MemoryStream memoryStream = new System.IO.MemoryStream())

            {
                workbook.SaveAs(memoryStream);
                memoryStream.WriteTo(httpContext.Response.OutputStream);
                httpContext.Response.Flush();
                httpContext.Response.End();
            }

}

After exporting the file, the ClientEvents-OnResponseEnd of radajaxmanager is not firing in Safari browser on MAC, I want this event to be fired to hide an image. It is firing in IE and Chrome on both MAC and windows but not in Safari. Please suggest.

Thanks in advance.

I have an asp.net application hosted on IIS and while the site works perfectly on my local dev machine once I upload it to a web server running IIS, all the controls look wrong.

The runtime DLLs have been installed on the server also.

Not exactly sure why this is happening but I suspect it is some config issue.

See below for how it behaves.

Any idea on a fix?

I am unable to exclude ajax enabled control (Button2) that resides inside panel (PanelButtons) as shown below. I tried to use the following code, I don't get any errors, but the button click is not working. I tried by using RadScriptManager's RegisterPostBackControl method. I also tried to disable AJAX via the OnRequestStart event as well as InitializeRequest event. None of them seems to work. So, is there any better solution for this scenario? Thanks.

Hi,

How can I have the dependent drop down n Grid filter, for example a grid contains Country , City , Train stations.and User select country,the filter is applied on grid but the city should also need to rebind with the country filter value.

This is my first time to use Telerik controls.

Hello,

I have a hiearchal radgrid with a parent level that has 2 key columns.

For example:

ID, Sequence, first_name, last_name

This can result in data that looks like the following:

1, 1, John, Doe
1, 2, Adrian, Shepard
2, 1, Mary, Jane

That child level has:

ID, Sequence, Data

So you can have data that looks like the following:

1, 1, 0.256
1, 2, 0.944
2, 1, 0.109

How can I code the grid so that the child level uses both ID and Sequence as a composite key when the radgrid is built entirely in code?

At the moment I use:

How do I code it so that it references both ID and Sequence as the relationship so that the grid looks like:

John, Doe
     0.256
Adrian, Shepard
     0.944
Mary, Jane
    0.109

instead of:

John, Doe
     0.256
     0.944
Adrian, Shepard
     0.256
     0.944
Mary, Jane
    0.109

which is wrong, since it is repeating the values on 2 rows because they share the first part of the relationship instead of also considering the second column.

I've looked in the documentation but the only information I've found on creating a composite key relationship involved doing so in the HTML, which is not an option for me as the radgrid is 100% generated in VB code on the server side.

Thanks for any assistance.
