[Solved] Radconfirm buttons

Here's the scenario I'm having issues with. In the grid, when clients clicks on whatever rows, a modal window will pop open with more details of the row selected. Whenever the "X" on the top right corner of the modal window is clicked, this will show a popup box (default) with two buttons "ok/cancel". I just wanted to know, is there a way to set the buttons from "ok/cancel" to "yes/no" within the current version? I've looked at and searched and tried most of the suggestions but wasnt able to resolve the issue I'm having. Please give me your input or any suggestions as to how I can resolve this issue.

Allow Scrolling Using Javascript

Initially AllowScroll=False in RadGrid

I have wrote code as below in javascript

var grid = $find("<%= RadGrid3.ClientID %>");

then

grid.ClientSettings.Scrolling.AllowScroll = true;

grid.GridDataDiv.style.height = "150px"

but GridDataDiv returns null in this case

but when AllowScroll=True in RadGrid

then

grid.GridDataDiv.style.height = "150px" this line of code works.

Why

grid.ClientSettings.Scrolling.AllowScroll = true;

is not supporting..

i want to set AllowScroll using javascript becoz if records are less then no need of scrolling.

[Solved] Changing default node behaviour

Hello,

I want my treeview nodes to behave slightly differently to the default in that when a node that has child nodes is clicked the postback is disabled and the node is simply expanded. I will be wanting to raise a postback and fire the node click event when a node that does not have child nodes is clicked.

I tried a server side approach on the node data bound event by trying to count the e.Node.Nodes to see if it had children that way but it was always returned as 0. Is there a server or client side approach I can use to achieve the node behavior I require?

Thanks,

Michael

RadProgressBar can't apply background image in Chrome

I download demo from http://demos.telerik.com/aspnet-ajax/upload/examples/customprogress/defaultcs.aspx

And then I tried to apply a background image to progress bar in Chrome. The version I currently use is 2009.1208.

Is it a bug?
Here are my steps:
1. Pull down demo page and compile it as local site
2. launch page from Chrome
3. Open Developer Tool and try to update the CSS for .RadUploadProgressArea_Default.ruProgress.ruBar div
4. Change the background image as below:

background-image: url(http://localhosts/images/back.jpg);

5. Nothing happens. The back.jpg can be applied successfully in FF or IE.

Do I do something wrong?

Scrolling in RadGrid

Hi ,

I have mentioned the code for scrolling a grid like

</Scrolling>

</ClientSettings>

also i have set PageSize=20 and Height = 400Px

But when there is only 1 record there is empty space between 1st record and footer.

So how can we avoid that space when there are less record .

Client Select Column -- Mouse Over Style

Hi, I just got the latest DLL as of Jan 5, 2010. One change to the grids is that Grid Column Headers that are groupable / reorderable now use the Compass like Arrows on mouse over. This works fine but when you mouse over a checbox in the Client Select Column' Header it should change back to the hand or default mouse icon.

Multiple selected items when AllowMultiSelect is false?

I have a grouped grid, with AllowMultiSelect set to false. If I select a visible item, i.e. in a group that is expanded, then select another, the original item is unselected, as expected. However, if I select an item, collapse the group that it resides in, and select an item from another expanded group, I am seeing 2 selected items in the SelectedIndexChanged event. If I expand the original group, I see both the original item and the newly selected item are both selected in the grid. Is that by design? For now I will try to code around it.
