RadWindow Through RadGrid and RadPanelBar

[Allan]

Telerik,

I am trying to access a cell in a radgrid while using that value as querystring parameter to open a radwindow.  The radgrid is contained in a radpanelbar.  Please let me know what I am doing wrong.

Thanks,

Al

Svetlina,

Than you for the reply.  I am getting a javascript error before the radopen call in the javascript method.  When I click on the LinkButton shown below, I get "Message: 'ClientID' is null or not an object".  I believe the problem lies in the code that gets a reference to the RadGrid.

Thanks,

Al

Hello Allan,

As far as I understand the scenario you want to achieve is the following one:

http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=window

I belive that the faster way to implement it is to use the provided online demo as a start point and to us ethe same approach if possible. If this apoproach does not work for you, provide more details why and we will think of another reasonable solution for the problem.

On a side note, when you install RadControls, our online examples projects are automatically installed on your computer and you can not only examine their full source code, but also extend them further in order to meet your requirements.

You can open the demos from here:

Start\Programs\Telerik\RadControls for ASPNET AJAX\Open Sample WebSite In VisualStudio

The actual location on your hard disk is the following one:

C:\Program Files\Telerik\RadControls for ASPNET AJAX \Live Demos

I hope that this information is helpful.

Kind regards,

Svetlina,

Thank you.  The example worked for  me.  However, I have another question:

How would I expand a RadPanelItem using a click event from a button contained in a RadAjaxManager control?

Thanks,

Al

[Svetlina Anati]

Hi Allan,

I suggest to use the button's OnClientClick event and to expand the item by using its expand() method - all this can be done on teh client without a need of an ajax request to the server. More information about the expand method is available below:

http://www.telerik.com/help/aspnet-ajax/panel_clientsideradpanelbaritem.html

If you prefer to expand the item on the server, you can use its Expanded server property as explained below:

HI
I'm using radcontrols in my asp.net website.
And these controls visually and functionality wise nice.

I have one scenario .
I have radpanelbar with 4 panel items.
each item contains one radgrid.
Now I'm binding every grid with theie needdatasource event.
My problem is suppose user select first item  can go through radgrid paging at pageindex 5 and if he collapse the current panlelitem and expand other and comes expand the previous one still he will see the radgrid with pageindex 5.
So I want bind the grid while expand the panel item.

Hope u understand my problem.

please help me as early as possible.

Hi Ram,

This issue is not related to the RadWindow and I suggest that you post your questions in the correct section in the future, as this would help them get to the right people who would be able to better help you.

As far as I understand your scenario you need to rebind the grid when you expand its panel. This can be done via an AJAX request in the OnClientItemExpand event of the RadPanelBar.


All the best,
Marin
