hello 

I want to export RadChart to excel so first Iam saving it.

following is my code

 Protected Sub btnSaveChart_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSaveChart.Click
        Try

            Dim ms As New System.IO.MemoryStream
            RadChart1.Save(ms, System.Drawing.Imaging.ImageFormat.Png)
            Page.Response.Clear()
            Page.Response.ClearHeaders()
            ' Page.Response.AddHeader("Content-disposition", "attachment; filename=Chart.png")
            Page.Response.AddHeader("Content-type", "image/png")
            Page.Response.BinaryWrite(ms.ToArray())
            Page.Response.End()

        Catch ex As Exception

        End Try
       
    End Sub

But it does not work  , it gives following error

  Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Hi,

I have the scenaio in chrome and firefox:

1. insert any from element using the toolbar button, for example a button
2. the cursor is set on the button to enter a text for it
3. try to enter any text. The resulted html is:
Text is added fter the input tag.

In IE it works fine.

Is there a solution for this?

Hi, anyone knows how to round the numbers on an x axis, I have values like 2, 3  4 and my a axis has 0 0.5, 1, 1.5 , 2, 2.5 etc

how do I only show 1, 2 3 4 5 etc? and hide 0.5, 1.5, 2.5

These are products sales, I cant show halves ...

thanks.

Instead of using just one table to bring back some data (see the following):

http://demos.telerik.com/aspnet-ajax/grid/examples/databinding/net35datasourcecontrols/defaultcs.aspx

is it possible to generate a LINQ query based on multiple entities to bring back the data?

Otherwise, just the one table is good fro DropDowns, but not for querying data against multiple entities and having it come back into the grid.

I want to retrieve some data for a grid via client-side pagemethods via the following:
http://www.telerik.com/help/aspnet-ajax/grid-client-side-binding.html

After executing the checkbox2 clicked event, a "GetData" pagemethod is executed to retrieve results for the grid in the updategrid function.

After the results come back, instead of performing the clientside rowdatabound event, if I have a corresponding event set up on the grid at design time to execute it via server side, will it go ahead and perform that server side rowdatabound event.

Thing is getting data may be expensive depending on when you do it. If I can get the data in certain situations via a page method, I can let the server side rowdatabound event handle each row coming through and apply what is needed.

Or will it be a lot faster leaving it client side. If that's the case, why have any server side programming to begin with if it's going to take a lot longer? Do we need to do everything client side?

The above I assume would simulate CallBack events similar to what DevExpress has, I don't see any CallBack events with the Telerik controls other than this type of programming.

Any feedback would be much appreciated.

hi
i want to have 3 columns in radgrid. 1st column is gridNumericolumn and 2nd and 3th are gridButtonColumn. i want when user clicked on one of button, set a value in numeric cell (for example 600) and when clicked on another button, set another value in numeric cell (example 400) in client side.
help me please.

I am getting this error: Uncaught Sys.InvalidOperationException: Sys.InvalidOperationException: Type Telerik.Web.UI.ExpandDirection has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.
On all my pages that have the RadTreeView control. Everything was working until I update today through the control panel. Any Ideas?
