Hi!  I'm running into an issue when adding a JavaScript method to the 'OnClientClicked' of a RadButton.  I receive a JavaScript error "this._postbacksettings is null" and the button click event handler in the code behind never fires.

There is no validation on the aspx page, and the button is contained within a RadPane.  The button has even been Ajaxed to see if that would resolve the error, but did not make a difference.

Essentially I'm trying to disable the button and change it's text once a user clicks on it so they cannot click more than once while the 'click' event handler for the button in the code behind is completing.

Here is the JavaScript code and the aspx for the button:

I have similar logic working on another page without any problem.  Though on the other page there is validation and in the Javascript I have an 'If' clause that checks if the page is valid before disabling the button and changing it's text.

Could someone help me understand why this is happening, and what I may need to do to fix the JavaScript error?

Thanks!

hi,

My Browser is IE8. I am using comboBox like that;


When I convert my scriptmanager EnableHistory propert TRUE, then OnItemsRequested not fired. On chrome and mozilla it is working very well. but on IE8  not work. if I close EnableHistory false then it is working.. 

Conditions;

first click combobox. you will see, the data is coming. then click button and postback , add history property. After that click again combobox, the data not come.. 

I have two questions regarding the grid.  One is a problem and the other is a "how to" or "can I".

(1) I have a grid which is used to page through search results (refer to attached graphic radgridquestion1.png).  The first page of the grid displays just fine, but when I click on the grids 'next' button, the page is displayed with nothing but blank space where the grid was on the first page (refer to attached graphic radgridquestion2.png).  The following code is the definition of the grid in the .aspx file.


Obviously, I don't understand why the second page won't display.  Any ideas or assistance would be greatly appreciated!

(2) A "how to" question:  In the first attached graphic, you can see search criteria in the left-most column, the grid containing results in the middle column, and the right-most column is blank.  I will be putting a small Google map in this space and want it to only contain "push pins" for the properties displayed in the current page of the grid.  Is there a way I can do this?  How and in what grid event would I be able to put the code to add the "push pins" each time a new grid page is displayed?  In what event would I place the code to "clear the map" to ready it for the next n number pins?  Feel free to ask questions if I did not explain myself adequately.

Thanks in advance for your help.  I know the attached page still looks a little rough, but it's still a work in progress!

Thanks again!

Lynn

I just wanted to make everyone aware of a small mistype in the documentation for ASP.NET AJAX Q1 2011 SP1.

In an examples listed you have:

protected void HandleNodeEdit(object sender, RadTreeNodeEventArgs NodeEvents)
{            
    RadTreeNode nodeEdited = NodeEvents.NodeEdited;
    string newText = NodeEvents.NewText;

    nodeEdited.Text = newText;
}

which, of course, should be RadTreeNodeEditEventArgs.

URL to the help page is below.

Hi there,

Is there a control I can use which will show a loading image as part of a list? For example, I want to show the progress of multiple actions in the following format:

<green tick>    Syncing Item A
<red X>    Syncing Item B
<loading image here>    Syncing Item C

Basically, a loading image needs to be displayed next to the item which is currently being synced. When an item has been successfully synced, a green tick needs to show next to the item. If an error occurs with the sync, I want to show a red X.
