I have a RadTabStrip that has RadMultiPages that contains ascx controls that contain RadGrid. This Tabstrip/Page exists as a nestedcontrol inside a RadGrid (master). One of the ascx controls deals with 'database' messages. This control using the code reccomendations for binding .. i.e. gridMessage.rebind() to fire the GridMessage_onNeddDatasource to use Linq to supply data for the RadGrid Datasource.

All works ok until I use the paging / move to next page. What I see is that the grid disapears when moved to page 2, even though I see the onNeedDatasource method fire and the data supplied. I then Click to go back to page 1 of the grid and find I get the number of rows for a page displayed as empty, and images that exist in an ItemTemplate column are displayed.

I have tried recreating the control from scratch and find I get the same results. In the RadTabStrip/RadMultiPages I also have 3 other ascx controls that contain the RadGrid, but the data is displayed and Grids correctly perform. Im not sure why this particular message RadGrid breaks and wonder if anyone can shed some light for where I look to make a fix.

I have also had various issue related to refreshing and use of RadWindow controls on another RadGrid that is found in three areas of my app. In each senario whereby this specific control exists (On own in a page, inside a RadMultiPages in a nestedcontrol of a master RadGrid, and in a RadTooltipManager popup window.) I find that the instance of this control in a page on its own works well and RadToolTips, RadWindow popups, and row colouring work well, however the instance in the RadMultiPage does not action tooltips or open RadWindows, and the instance inside a RadToolTipManager popup (which is also inside a RadMultiPage) will not allow row selection that does not validate selectedvalue as not null. I had a feeling that the problem related to the RadAjaxManager / RadAjaxManagerProxy controls that are used to trigger refreshing, however the RadAjaxManagerProxy exists the same in each senario, although different RadAjaxManagers exist in each page/masterpage. Do you have any tips for configuring the RadAjaxManager/RadAjaxManagerProxy for dealing with the same control (ascx) in different areas of my application to preserve the same refreshing / RadAjaxToolTip / RadWindow actions / features throughout the application?

This project is fairly large and often pages are made of several ascx controls. To supply all code would not be possible, however I can confirm that the coding of binding of controls has been set exactly like samples found on your site and methods for databinding do adopt the 'onNeedDatasource' approach.

The version of the controls that are being used are: 2009.3.1208.35

Hi ALL,

          I have used rad grid with inline editing functionality, i have define RadGrid_UpdateCommand event for updating record, when i click on update button event get fired, but in event i used following code

var  EditedItem: GridEditableItem;
       KeyValue: Int64;
       NewValues: Hashtable;

EditedItem := e.Item as GridEditableItem;
 
  KeyValue := Int64(e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]['ID']);

  NewValues := new Hashtable;

 e.Item.OwnerTableView.ExtractValuesFromItem(NewValues, EditedItem);

But problem is here for NewValues hashtable i got null values, i didn't understand that what is the problem behind this.

I got the following error.

specified argument was out of the range of valid values. parameter name index

is there any problem to binding grid or something else.

Please help me.

Hi,

For RadGrid, is there a way to assign different CSS to each column of the filter row?

I can assign CSS class to Header, Footer and Item columns by changing HeaderStyle.CssClass, FooterStyle.CssClass and ItemStyle.CssClass. But I don't know how to do that to Filter Row column.

TIA 

Hi Telerik,

I have a RadMultiPage created at design time. I add page views to it programatically. When I add just one page view to the RadMultiPage -- all is well. I am able to refresh the page, work with the page, etc etc. Everything is fine.

When I add a second PageView to the page I see the height of the page views awkwardly restricted.

I have ViewState disabled. I regenerate the controls in Page_Initialization. Here are all the relevant methods. Do note that I played around with this a fair bit, and am confident I am regenerating the controls properly... I realize that I am breaking the "Regenerate Tabs and PageViews when NOT postback), but because I have ViewState disabled this should not be the case.

Here is the code where I allow the user to create a new RadPageView dynamically. This is located inside of an event after the page has been rendered fully.


SetupBase isn't relevant to the issue. I can confirm that the issue arises SOLEY on when I regenerate the second page view. 

This method is called in Page_Load:


Here I recreate the pageView with the same ID as was known before and re-add it to the MultiPage. The MultiPage does not know of this PageView, nor does it seem to retain any information from the old page state once I step into Page_Init (my fear of regenning in page_load).

I also call this method in Page_Load. It handles the corner-case of 'first time load' where there are no page views to regenerate. As such, I create the first one and save it off so that when the user refreshes the page it is regenerated instead of created anew.



Okay, so this is a bulk of code, but basically all it says is "If there is no PageView, create our initial and save it."

This works well. I am able to create the initial PageView, it is the proper height. I am able to refresh the page and it retains its height information. If I close my page, reopen it, it still retains the correct height. I am confident that this is working for 1-pageview multipages.

I have attached two images which highlight my issue with accompanying HTML mark-up.

Is this a common issue? Thanks.

Hi,

I have two questions wrt scheduler.

1. I have checkboxes on each time slot, for the blocked timeslot, the check boxes are getting overlapped by the appointment, PFA the screenshot ChkboxOverlapped.jpg. How can I resolve this?

2. I need check box for the blocked appointments and there should be only one check box per appointment irrespective of the timeslot. Please suggest me the way.

Thanks,

Hi,

is it possible to show a contextMenu with different items according to the item clicked. By example, for this treeView :

    LevelA1
    LevelA2
        Level2A
        Level2B
    LevelA3

Level2A et Level2B will have a context menu that show "Edit" and LevelA1-A2 will show "ADD" and LevelA3 will show "Delete". 

Thank you.

Hi,

I was binding the RadGrid using NeedDataSource w/ a generic collection to separate the presentation from data layer. during the binding, I kept receiving a message that points to the column for my DataKeyNames in the MasterTableView - ResultsID

<

 

 

MasterTableView ShowFooter="false" DataKeyNames="ResultsID" EditMode="InPlace"

 

 

 

CommandItemDisplay="TopAndBottom">

...the error points back to my generic collection for this column..the column exists within my code though....is there anything special that I should know?

 

 

 

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

 

{

 

 

using (dl = new WellVentDataLayer())

 

{

 

 

BindingList<WellVentEvents> oEvents = dl.GetWellVentEvents();

 

RadGrid1.DataSource = oEvents;

}

 

}

Hi
