Finding RadGrid inside of PageView

Setup: (this is based on one of Telerik's example scenarios)

One RadTabStrip with 3 tabs
Each tab has a single PageView
Each PageView is dynamically loaded with a UserControl
Each UserControl contains a RadGrid
Each RadGrid contains a "clientselectcolumn" and allows client-side row selection

Scenario:

Select a row in grid on Tab1
Select Tab2
Select Tab1

Problem:

If I were performing this operation server-side I would use code similar to the following to find the grid:
RadGrid rg = RadTabStrip1.SelectedTab.PageView.Controls[0].FindControl("RadGrid1")
Client-side, I have been able to obtain the PageView via the onTabSelected event:
args.get_tab().get_pageView(). Unfortunately, there isn't a "findControl" method so I cannot find "RadGrid1".

Question:

How do I find the grid on Tab1 via client-side code?

            </body> 
        
            </html>

it seems that radcombo box can not foreget it's focus and stick with that , therefore when i play with 2 buttons (enter=13 and upper key=38 as you see in the upper code - Jquery) For Changing Their Focus so RadComboBox OnClientFocus does not fire until i click on my page and Click On the RadComboBox Again...
These Lines do not work:
1-$('input[id$=RadComboBox1_Input]').blur();
2-$('input[id$=RadComboBox2_Input]').blur();
how can i take focus off from radcombo box and destroy it's highlight?
thanks a lot

Pager is not displayed

I have RadGrid control on my page, when I look at it in design view it shows the pager. When I compile the project I see no pager at the bottom of the grid.

Here is my code for the grid.

How to display Session Timeout based on Inactivity time set in WebConfig File.

Folks, Environment VS 2010 with RadControls for ASP.NET AJAX Q2 2011 SP1. I am using below Telerik Demo for Session Time out.

http://demos.telerik.com/aspnet-ajax/notification/examples/sessiontimeout/defaultcs.aspx

This above approach is based on preset timeout value within the .aspx page. But I would prefer to show the Session timout inactivity alert based in value set in my Web Config file (here is 20 minutes).

My webconfig file...

<system.web>

.......

<sessionState

mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424"
sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes"
cookieless="false" timeout="20"

/>

.......

</system.web>

If possible, will very much appreciate if any sample code is provided for this solution. Thanks a lot.

Clearing Custom Text Box when Node Unchecked

I've created a usercontrol that allows users to select "interests" using a RadTreeView so that it can expand and display a hierachy.

In the node template I added in a text box for users to type in a free response if they choose certain fields. It's all working beautifually, with one gotcha. If a user unchecks the box, the text is still display until

1) the refresh the page
2) I databind the tree

Each of those are not overly desirable solutions, 1) being confusing to the user, 2) loses the state of any expanded nodes.

As the textboxes are created dynamically, they don't have ID's that I could reference with a FindControl and clear them when the appropriate check box is unclicked.

Any thoughts?

Chrome, Safari: copy \ paste text from editor to editor add some strange formatting

Hello,

We found some strange problem with copy \ paste functionality which can be reproduced on your demo in Chrome and Safari browsers.

Steps to reproduce:
1. Open editor in Chrome.
2. Write some text like "Test copy paste".
3. Copy this text (you can use Ctrl+C or browser Copy).
4. Paste this text in to editor. Text is paste with some additional formatting like:

<div style="padding-top: 3px; padding-right: 3px; padding-bottom: 3px; padding-left: 3px; background-image: none; margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; text-align: left; word-wrap: break-word;">Test copy paste</div>

Could this problem be resolved in some way? Because we support these browsers and our users can do very often such actions.

I used Google Chrome 14.0 to reproduce this bug.

Kind regards,
Anna

Exclude specific controls from AutoTooltipify

We recently implemented AutoTooltipify. Looks great but then we realised that sometimes we would want to exclude certain controls. Namely, tooltips within tooltips. So two questions:

1. Has anyone looked at the inner working of AutoTooltipify and come up with a nice way of excluding specific controls/regions? I know we could manually add controls using TargetControls, however, if 99% of controls are auto, it's easier to exclude one or two that we don't want. I imagine performance would be better too.

2. We have an autotooltip that opens on mouse over and closes on mouse out (of tooltip). The problem is that we have objects inside the tooltip that also have tooltips. Moving the mouse over those inner objects displays a tooltip in the top left of the screen and closes the outer tooltip. Presumably the controls don't know where to render the inner tooltip and the outer tooltip is no longer "active" so it closes. Any suggestions on how we have inner tooltips in the correct position AND don't close the outer tooltip? Perhaps there should be a property in addition to AutoTooltipify that disables inner tooltips?

Enjoy the challenge! :)
