Hi,

I am trying to Bind RadhtmlChart my column name contains '.' when this appears in the column it is throwing error,how can I handle this.

EX:

       dt.Columns.Add("id");
        dt.Columns.Add("data..."); // This contains '.' at end of column 
    
        DataRow dr = dt.NewRow();       
        dr[0] = "2011-12";
        dr[1] = "500";
        dt.Rows.Add(dr);
        ColumnSeries cs = new ColumnSeries();
        cs.LabelsAppearance.Visible = false;
        cs.Name = dt.Columns[1].ToString();
        cs.DataFieldY = dt.Columns[1].ToString();
        radChart.PlotArea.XAxis.DataLabelsField = dt.Columns[0].ToString();
      
        radChart.PlotArea.Series.Add(cs);
        radChart.PlotArea.YAxis.MinValue = 0;
       
        cs.LabelsAppearance.ClientTemplate = "#= category #";
        cs.TooltipsAppearance.DataFormatString = "{0:N0}";
        cs.TooltipsAppearance.ClientTemplate = "#= category #: #= value #";
        radChart.PlotArea.XAxis.Type = Telerik.Web.UI.HtmlChart.AxisType.Category;

Hi
I am converting to the latest controls and I am getting the following runtime error:

    intKey is neither a DataColumn nor a DataRelation for table GroupedTable0.

This code is currently working with version 2010.3.1109 of controls.  The data for the grouped grid is coming from a stored procedure via a strongly types data adapter (i.e. dataset).  I am applying a filter on the data, prior to manually binding the grid.  When I bind the grid I get the above exception.
I have added a intKey column with visibility set to false to the columns collection but that did not help.

I can't seem to bind data to a drop down tree.

Markup:

Code Behind:

I should also note, this is being called from the "ItemDataBound" event on a RadGrid [adding a new item, haven't looked at editing an existing item].  The markup lives in the EditFormTemplate of the grid. 
Any ideas?

Hello!

I can't seem to find a way to implement custom paging in the RadFileExplorer control. I have created my own ContentProvider and I have tried to enable custom paging on the internal grid, but no paging events seems to occur. I really need custom paging since our database contains a lots of object and I don't want to retrieve all of them at once (some folders even time out). 

Is there a way to do this or must I create my own FileExplorer?

Best regards,
Patrik Edberg

Hi,

i'm very new for telerik controls.

i have studied for the custom handler function using asyncUpload Control, to get image preview with the link (http://demos.telerik.com/aspnet-ajax/asyncupload/examples/imageuploader/defaultcs.aspx).

the above demo link showing how to get preview image automatically saving and database and retrieving from that database. and i'm quite confused.

i have  scenario for new user profile registration

i have fields example( name,email, photo)

so user will upload profile image and able to see the preview of the Image.

i want to save image in tempfolder and get preview. and  finally when i click on submit button, it should save image on original path folder and also save Filename with other fields data into database. and Finally delete file from temporary folder

Please some can post the script to match my scenario

Appreciated for better response
