RadComboBox with RadWindow popup edit

Hi,

How do you popup a RadWindow to allow user to enter some input, close the window, and add the inputted text to the RadComboBox?

What is the best way to do this? I am trying to do this in a webpart.

Can controls be inserted into RadWindow programmatically?

How is information passed between the RadComboBox and RadWindow?

I tried doing this.

RadWindow popupWindow = new RadWindow();

popupWindow.VisibleOnPageLoad = true;

popupWindow.Modal = true;

Controls.Add(popupWindow);

Popupwindow will show up but how do I add controls to the popupWindow?

Please help! Thank you!

Horizontal orientation for certain nodes

Hello Telerik Team,

I'm hoping the answer to this would be yes.
Can i have certain nodes' orientation set to horizontal based on an attribute value on the node? If so how can I achieve this?
I looked at this forum post but couldn't really figure how i could achieve that only for few nodes based on a condition.
I would really appreciate any help.

Thanks much,
Phani

RadAjaxPanel, Viewstate, and Dynamic Controls

I have a function that adds dynamic controls to an RadAjaxPanel. The dynamic controls are RadComboBox and some others. Everything is working as expected. On page postbacks, the values for these controls are properly set.

Outside of the panel is a button. If the user selects this button, the contents of the RadAjaxPanel are modified. The update panel looks great at the end of this postback, as it has the new control and data. The problem happens on a subsequent postback. During the next postback the update panel is recreated with the correct controls however the data/viewstate for the controls is gone. I can only assume that the controls that were added during a postback client event to the update panel did not save the viewstate.

The subsequent postback does not contain the state for the control that was added. My sample code is below. Here is how to see the problem:

1. The page displays with two comboboxes.
2. Select an item in the first combobox and the second one repopulates. This is working as expected.
3. Press the button on the page and the update panel is created with a single combobox and a new set of values. This is working as expected.
4. Press the button again, as this time it just implements a standard postback with no changes. THe combobox no longer has its values.

Since the viewstate of the objects happens after the PreRender event, there is no reason why the state should not be saved. What is happening?

[Solved] maxLength of NodeEdit

Hello,

With javascript, I can change the maxLength of an edited node's input textbox, but it appears that only 50 characters of the edited text are actually saving. Is there a way to increase the maximum length to something greater than 50, say 255?

Thanks,
Ian

WebKit Browser w/ Ajax Enabled RadGrid

There seems to be some issues with an Ajaxified RadGrid when using WebKit Browsers like Safari or Chrome. Both seem to issue back to back requests (and way too many responses); these are not present in IE or Firefox. This is causing an issue due to the fact the loading panel is immediately turned off after the first response, while second request continues to process with no panel (which allow our users to access to areas they should not have while data is being processed). We're currently using Q2-2009 controls in the affected project.

The sample below is setup such that a user may end their filter entry with ENTER, which kicks off an onclick event for a hidden button. This is done so a known control causes the request and can be identified on response. Attempting to decipher which internal RadGrid element caused the response is a bit cumbersome. You will notice that IE and Firefox only deal with the hidden button, while Chrome and Safari seem to push the RadGrid Filter Textbox into the mix. Is there any work around for these browsers? Is this a known issue?

SafariAjaxRequestProblems.zip

*** Please note this issue is not isolated to the RadGrid (we have seen it happen it other places), but this example was easy to pull out of our main project. I'm sure if we can solve this issue, we will be able to remedy it in other areas as well. I've already generated a much simpler sample and issued it in the radinput forum as this seems to be the direct source of the problem.
