Hi Telerik,

Error occured in the grid when try to save with special character "<>" .
Refer to the attached screen shot.
When i try to save it throws error.

Regards

I have MasterPage and its ChildPage. On ChildPage I have JavaScript function that is raised on RadSplitter.OnClientLoad="abc". Basicly, this fires on page load as last client event and that is good for me to do something.


This works normally.

Now I want to add one JavaScript-to-AjaxRequest function to MasterPage, I want to check something from database when every ChildPage gets focused, something like this (this is on MasterPage):


Because I can't have two AjaxManager (on MasterPage and ChildPage), I put AjaxPanel in MasterPage.




So, when I request ChildPage in browser, both AjaxRequests should be fired, first one in MasterPage and then from ChildPage. RadAjaxPanel1.ajaxRequest from MasterPage works but AjaxManager.AjaxRequest from ChilPage don't work! When I remove function from MasterPage, function from ChildPage works normally and vice versa.


How to set both AjaxRequests work together, simultaneously? Obviously there is some conflict beetween them.


There is many articles on Internet about multiple AjaxRequests on same time but I don't understand what to do to correct problem.

hi

I have dynamically initialized a treeview(i.e from backend)  and the treeview contains checkboxes and i want to get the details of the node i have selected in the checkbox

My last challenge to solve and this project will work.

I have a Delete button in a  DETAILS TABLE.   Using the GridButtonColumn with CommandName="Delete" and UniqueName="Delete Entry"

I need to be able to hide these based on certain conditions.  I would probably put the code in the ItemDataBound.  I would need to reference my second DataKeyName (QTRInserted) to decide to Hide or Show the Delete button.  I DO NOT WANT TO HIDE THE ENTIRE COLUMN.  Thanks.

Hello RadScheduler Experts,

For our radscheduler, we do not want to show the TimeLine on the header. But we do want to show the Day, Week, Month.
If you can please point me to how this can be possible.

Thank you.

Hello, I've an issue with client-side databinding of a RadGrid. In fact, when I do a .set_dataSource(<dataSource>) and a .dataBind(), data is successfully loaded in the RadGrid but the length of the property _dataItems doesn't change.

Here is the code of the RadGrid:

Here is the code executed in order to load data in the RadGrid:

Example to explain you more clearly my issue:
At the first client-side loading, 126 rows are binded in the RadGrid and selected. So the method .get_dataItems() and the method .get_selectedItems() returm 126 items, it's good. But at the second client-side loading, 4 rows are binded in the RadGrid and selected. The grid display 4 rows so it seems to be good again.. but in fact, when I try to do .get_dataItems() or .get_selectedItems() it returns 126 items again! The 4 first items in _dataItems property are the 4 correct items but there're 122 other items (old items).
I tried to manually delete all items in property _dataItems of the grid but it doesn't work.

I need to know which items are selected so it's a real problem.

Thank's for your help.

 

 

 

How can I create a a rotator with "FormCode" mode while being able to start that rotator automatically when the page loads? I need a complete sample code for the call.

I've used the following JavaScript/JQuery code for FormCode management:

 

And the following code for the calls:

 

 

 

 

 

 

 

 

 

However, I cannot start the rotator on the page load. Tried to use this code in the in the MyRotator_DataBoud event, but did not work either:  

 

 

 

 

Please show me the code that I need to write to start the rotator right after loading the page, and the location where I should place that code. Thank you.

Hello,

I'm opening a RadWindow that allows a user to enter a record into a database.  On the OnClientClose() event, I'm trying to refresh a RadListBox that is in a RadAjaxPanel in the parent page.  This seems like it should be straight forward but I'm not having any luck.  I'm new to web programming so I'm sure I just don't understand something.  I am making it to the code behind once the window is closed so I know the DataBind() is executing.  However, while I see the loading panel displayed the new item does not show up in the RadListBox.  Any ideas as to what I'm doing wrong?  Thanks!

i am using the example of related combo box

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx

The only problem, I am having is my combo box is inside the RadpanelBar. I could not figure out what to write for this

function pageLoad()
{
    // initialize the global variables
    // in this event all client objects
    // are already created and initialized
    countriesCombo = $find("<%= RadComboBox2.ClientID %>");    
    citiesCombo = $find("<%= RadComboBox3.ClientID %>");
}

when I do this
$find("<%= RadComboBox2.ClientID %>");    

It could not find the control because this combo box is inside the rad panel bar. can anyone please tell me the script to get the client ID of the control inside the radpanel bar,

any help will be apprecaited.
