InPlace Insert Row with Client-Side Binding

When I am in server side datasource binding, I can initiate an inplace editing row by firing an "InitInsert" command. However, when I am in client-side binding, there is no way to bring up such editing row without the RadGrid posting back to the server code and re-rendering.

Even getting the editing row with the server re-rendering, clicking the "Insert" linkbutton doesn't seem to post back the newly inserted data in the OnInsertCommand.

I found the example with Form editing using another grid from the Demo. However, it is not quite what I am looking for.

The reason I want to use Client-Side binding is because of its response performance. I hope someone has the similar issue can shed some lights here.

Thanks.

Vertical Dimension not resizing (at all)

Can anyone please tell me why this master page does not resize in the vertical dimension. I need for the RadPanel and all of the other Rad controls to resize properly. This is the last hurdle before this page works properly for our simplistic needs. I set all of the height properties to 100%. I just don't know what else to do!

Thank you,

Ryan Kirby

[Solved] Export to excel with hyperlink

Hi..
i have a column with hyperlink. i am exporting the grid in excel file.
i have set "ExportOnlyData = true" so it will not display data with hyperlink.
so to overcome from the problme i created on more column with same data without hyperlink.
initially i am setting it visible=false and while exporting i am setting it visible = true.
but it is not displaying the column in exported excel file.

code on export button click :

    
                protected void btnExport_Click(object sender, System.EventArgs e) 
        
                { 
        
                    dg.MasterTableView.Columns.FindByUniqueName("Delete").Visible = false; 
        
                    dg.Columns.FindByUniqueName("clName").Visible = false; 
        
                    dg.Columns.FindByUniqueName("clNamePrint").Visible = true; 
        
                    foreach (GridItem commandItem in this.dg.MasterTableView.GetItems(GridItemType.FilteringItem)) 
        
                    { 
        
                        commandItem.Visible = false; 
        
                    } 
        
                    dg.ExportSettings.FileName = Page.Title; 
        
                    dg.ExportSettings.OpenInNewWindow = true; 
        
                    dg.ExportSettings.ExportOnlyData = true; 
        
                    dg.MasterTableView.ExportToExcel(); 
        
                }

i have used custom paging in the grid.

this solution works fine with one gird in which custom paging is not used.

Thanks,

I have a RadGrid with a RadComboBox and linkbutton in a footer template of a GridTemplateColumn. When the linkbutton is clicked I want to check if the value selected in the combobox exists in a particular column in the grid. Does anyone know how I can accomplish this with Javascript? Thanks in advance!

Performance issue with Load Testing.

We are facing a problem with load testing on our application with Load Runner. The application is sustaining the load till around 1 hour, with 100 user. After this the application stops responding. On viewing the event log we find System.OutOFMemoryException being logged. We took the memory dump at the instance of failure and sent the dump to Microsoft for analysis.

The analysis from MIcrosoft is given below.
It shows a lot of pinned objects in memory. Some of whose GUID seems to be given. Also a screen with 4 RadGRid is creating many objects, as mentioned in the Summary below. Do you recognize the pattern given below? Can you please offer any solution? An early reply will be very much appreciated as this is urgent and may affect the Go-Live of a very big project.

We have a few pinned handles here, which are System.Object arrays:

Pinned Handles: 58

I looked at a couple of them to track down their roots, but couldn’t find any. The data in these appear to be something like this:

201cd4d0 6c69462f 20726574 4943432f 61465454 /Filter /CCITTFa

201cd4e0 63654478 2065646f 572f0a0d 68746469 xDecode ../Width

201cd4f0 32373120 2f0a0d38 67696548 32207468 1728../Height 2

201cd500 0d393032 69422f0a 65507374 6d6f4372 209../BitsPerCom

201cd510 656e6f70 3120746e 432f0a0d 726f6c6f ponent 1../Color

201cd520 63617053 442f2065 63697665 61724765 Space /DeviceGra

201cd530 2f0a0d79 676e654c 37206874 52203020 y../Length 7 0 R

201cd540 442f0a0d 646f6365 72615065 3c20736d ../DecodeParms <

Do you or your developers recognize this pattern?

I then looked up the System.Byte[] arrays...There are lots of these objects on the LOH, some as large as 8+ MB...

I traced some of these to PwC.Tobacco.Entities.TobaccoDisputeDocument & PwC.Tobacco.Entities.TobaccoNotice on thread 18. Further investigation shows that the source of these objects which are living long is Telerik.Web.UI.RadGrid, which roots PwC.Tobacco.Entities.TobaccoNotice via session. Session timeout itself isn't all that long - 20 minutes, but because they are in load testing, it appears to me that the process is running into this very quickly. Here’s the root:

ESP:347f2ac:Root: 2a0b61bc(Telerik.Web.UI.RadGrid)->

3c0426e0(ASP.pages_notification_viewpublishmsanotificationlist_aspx)->

5bcc7750(System.Web.HttpContext)->

1e0d21e8(System.Threading.Thread)->

1e0d4edc(System.Runtime.Remoting.Contexts.Context)->

1e0d4d50(System.AppDomain)->

1e11c29c(System.ResolveEventHandler)->

1e11b948(System.Web.Compilation.BuildManager)->

1e11c8b8(System.Web.Compilation.MemoryBuildResultCache)->

1e0e2a04(System.Web.Caching.CacheMultiple)->

1e0e2a1c(System.Object[])->

1e0e5614(System.Web.Caching.CacheSingle)->

1e0e5698(System.Web.Caching.CacheExpires)->

1e0e56b8(System.Object[])->

1e0e5740(System.Web.Caching.ExpiresBucket)->

4b0073d0(System.Web.Caching.ExpiresPage[])->

4b007454(System.Web.Caching.ExpiresEntry[])->

10771788(System.Web.Caching.CacheEntry)->

10771758(System.Web.SessionState.InProcSessionState)->

126649ac(System.Web.SessionState.SessionStateItemCollection)->

12664a0c(System.Collections.Hashtable)->

1316bedc(System.Collections.Hashtable+bucket[])->

1316becc(System.Collections.Specialized.NameObjectCollectionBase+NameObjectEntry)->

14acd12c(PwC.Tobacco.Entities.TobaccoNotice)->

Summary:

So there are 2 things that are contributing to the OOM here:

1. Many objects of type PwC.Tobacco.Entities.TobaccoNotice are rooted in session via Telerik.Web.UI.RadGrid

2. Pinned System.Object[] arrays.

validation happen only at server side after upgrading to Ajax

I was using a trial version of ‘RadControls for ASPNET’.

Now I have updated to purchased version of ‘RadControls for ASPNET AJAX 2009’.

All controls have upgraded to this version

But now all validation happens only at server side.

(I have used asp required field validator to validate telerik date picker).

But validation happen only at server side when I call page.validate()

it was happening in client side itself before.

what to do now?

Programmatically change controls in design view

Is it possible to programmatically open a web page in design view (in visual studio), loop through all of the controls and change the properties of every instance of one type of control? For instance, I'd like to change to change to background color of every textbox on a page. If I have a large number of textboxes on many webpages a programmatic approach to this is a real time saver. An example of the general approach would be most helpful.

Thanks,

CommandItemTemplate

Hi,
Please how can I hide the CommanditemTemplate border ? I try to set the border width to 0px in CommanditemStyle and try to make it White color but all that worthless .. so is there any way to do it so my CommandItemTemplate look like it is separate from the Grid

Thank you

Header Div Width with Static Headers

When allowScroll is true and useStaticHeaders is also true, the header div does not occupy 100% of the width of the containing div in FIrefox 3 (FF3). It works ok in Firefox 2, IE7, and Opera 9. In FF3, the grid header div stops where the scrollbar would be if the header div had scrolling.

              <clientsettings> 
        
                <scrolling allowscroll="true" scrollheight="150px" usestaticheaders="true" />

	protected void btnExport_Click(object sender, System.EventArgs e)
	{
	dg.MasterTableView.Columns.FindByUniqueName("Delete").Visible = false;
	dg.Columns.FindByUniqueName("clName").Visible = false;
	dg.Columns.FindByUniqueName("clNamePrint").Visible = true;

	foreach (GridItem commandItem in this.dg.MasterTableView.GetItems(GridItemType.FilteringItem))
	{
	commandItem.Visible = false;
	}

	dg.ExportSettings.FileName = Page.Title;
	dg.ExportSettings.OpenInNewWindow = true;
	dg.ExportSettings.ExportOnlyData = true;
	dg.MasterTableView.ExportToExcel();
