Grid Performance issue while using object datasources

Hi,

I am using radgrid binded to a list of business objects retreived from tier 2. I have written the code to get the list of objects in the grid_NeedDataSource method. But since this method is getting hit for any single operation like filtering or soting or paging, the response time is very high along with the network delays. Is there any way to get the list only once and do rest all logic at the tier 1 itself. Please help.

Regards,
Saravanan K

RADGrid client binding download link

Hello Telerik Team,

I am having RADgrid in on of the module of my application. In there we have linkbutton by which i have to download document.

So before i implemented client binding it was working on server side by Item command event. but as i have implemented client side binding i m not getting command argument which are given on client side by javascript.

so below is the code running on server side,

MemoryStream stream = TheWay.GetDocument("*", Number, "*", "*") as MemoryStream; 

Response.ContentType = contentType ?? "text/plain"; 

Response.AddHeader("Content-Disposition", "attachment;filename=" + attachment.FileName); 

byte[] buffer = stream.ToArray(); 

stream.Read(buffer, 0, Convert.ToInt32(stream.Length)); 

Response.ClearContent(); 

Response.BinaryWrite(buffer); 

Response.End();

Now, Can we do this thing in javascript or by web service? I m not sure abt this one.

Line chart problems

Hi,
Lets consider the following example:
I have a line chart with 2 chart series, which are serie A and serie B. The line chart has 2 Y axis. The primary Y axis is for chart serie A, and the secondary Y axis is for serie B. These two chart series A and B use the same X axis.
In the database, serie A has continuous data from 10/01/2010 to 10/30/2010. On the line chart, serie A will have 30 data points in total, from 10/01 to 10/30.
Otherwise, serie B does not have continuous data, It does not have data from 10/03/2010 to 10/06/2010. As a result of this, on the line chart, serie B will not have data points of 10/03, 10/04, 10/05 and 10/06. The data point next to 10/02 will be 10/07, for serie B. This also means serie B will have 2 data points less than serie A.

Questions: is there any way I can do so that series A and B have the same number of data points on the chart. The value of these missing data points will not be displayed, and will not be assigned as 0. What I want is the line chart still connects the two data-available data points.

Thanks,

[Solved] Opening a window in Form_Creating

I'm working on a Scheduler page that opens the add/edit form in a RadWindow. I based the idea on the External Edit in RadDock demo.

I have a question though.

I'm opening my RadWindow using code very like this from the demo...

ScriptManager.RegisterStartupScript(Page, GetType(), "formScript", "Sys.Application.add_load(openForm);", true);

I'd be interested to learn why this works when this ...

RadAjaxManager LocalManager = RadAjaxManager.GetCurrent(Page);

LocalManager.ResponseScripts.Add("OpenForm();");

doesn't.

TooltipManager and RadComboBox MasterPage

I have a RadToolTipManager on a master page and a RadComboBox on a child page. I am trying to show a tooltip for the combobox on the onFocus event. First off, the tooltip won't show using the ToolTipManager's showevent=onFocus property. If I set the OnClientFocus property of the RadComboBox to show the ToolTip via javascript, I get a javascript runtime error (Object doesn't support this property or method).

If I put the RadToolTipManager on the child page, everything works fine, but I need it to be in the masterpage. Any thoughts?

Thanks...
