Stepwise Explanation

 ddlTest.clearItems();
 ddlTest.trackChanges();
ddlTest.clearSelection();

   for (var j = 0; j < heat_no.length - 1; j++) {
                                        var comboItem = new Telerik.Web.UI.RadComboBoxItem();

                                        comboItem.set_text(heat_no[j]);
                                        comboItem.set_value(heat_no[j]);

                                        ddl_cast_no.get_items().add(comboItem);
                                    }
  ddlTest.commitChanges();

1. Above Javascript Code is Executed and My Combobox is filled Perfectly
2. Now if this Code is executed again it Displays new results that is ok
3. Let me execute again .. No Problem in Display
4. I am Making a Postback on server for Some other work
5. After postback is Shows me my combobox has 3 times duplicated values(Not that we have executed it 3 times).

If the Code is two times executed the value will be 2 times Duplicate executed
If the Code is 5 times executed the value will be 5 times Duplicate executed

I want it Without Duplicate

Hi Fellows,

Is there anyone has done exporting the inner grid data with the master/outer grid once clicking on the export button ?

Here is my aspx coding which may give you an idea :

I appreciate your help.

Hi,

I am trying to achieve a post back on enter key pressed. I found out that the RadButton's property UseSubmitBehaviour doesn't do anything? I would expect if this is true, the button to be actually a submit button and if false to be a normal button. This seems not to be true here.

As I found out this is not working out, I tried using asp.net control Panel and it's property - DefaultButton to see if it's going to help, but it didn't.

I am using the latest version of the telerik ajax controls library. How can I achieve autopostback on enter? I don't want to subscribe to keypress events and watch for enter key. This should be built in. How can RadButton render input[type=submit] instead of input[type=button]?

Thanks,

Ivan.

For the past day or so I have been seeing this message when creating a new style.

Failed to create skin!
A server error has occured.
We have been notified and will try to resolve it ASAP.
Sorry for the inconvenience.

Can anyone shed some light on this issue?
Thanks.
JON

PS. I was able to open an old style.zip file in the editor. I simply cannot create a new one.

Seems like if you have a multiline radtextbox with a multilined emptymessage (containing CrLf's) AND a tooltip, the emptymessage is set as the value of the textbox.

If only using Lf's to seperate the lines it is working as expected


generated html that is working (without Cr's):
<input ...... value="{"enabled":true,"emptyMessage":"EmptyMsg1\nEmptyMsg2","validationText":"","valueAsString":"","lastSetTextBoxValue":"EmptyMsg1\nEmptyMsg2"}">

generated html that is working (with CrLf's):
<input value="{"enabled":true,"emptyMessage":"EmptyMsg1\r\nEmptyMsg2","validationText":"EmptyMsg1\nEmptyMsg2","valueAsString":"EmptyMsg1\nEmptyMsg2","lastSetTextBoxValue":"EmptyMsg1\nEmptyMsg2"}">

I've manually fixed this by removing any Cr's from the EmptyMessage, but seems like a strange bug as it is only a problem when a text for .Tooltip is used.

On a custom edit form for a grid, I have two bound decimal fields.
I want to update a third calculated textbox when the user changes any of the two bound fields.

I followed Dimo's example from an old post called "ascx editform with calculation textboxes when onfocus or onblur", but I was never able to make it work.

Could someone take a look on the attached screen and give me an idea on how to do this? Thanks

--------------
Obviously, I am trying to update the "Total Cost" textbox, if the user changes the Quantity, or the Unit Cost textboxes, which are both bound to the database.

Hi,

I'm using 2013.2.611.40 Telerik RadGrid.

I'm trying to use Batch editing mode with a GridTemplateColumn. If I specify ColumnGroup property, when the cell is clicked a JavaScript error is raised in _isColumnEditable (Unable to get property _data of undefined or null reference). If ColumnGroup property is removed all is working fine and edit textbox is shown.


Thanks in advance.

Hi,

I'm using 2013.2.611.40 Telerik Radgrid with Batch editing activated.

I have a GridTemplateColumn with ColumnGroup defined. When I click on the cell a JavaScript error is launched in _isColumnEditable (Unable to get property _data of undefined or null reference  in var h=g._data).

If I remove ColumnGroup property from GridTemplateColumn all is working fine and textbox is shown for editing.

I have plenty of images path of my Rad Editor set to a folder with many sub folders.  Each of those sub folders has dozens of images in it.  On the production server, it takes almost a minute just for the Image Manager dialog to open and show the sub folders.and also taking long time on pagination as well filtration  

I made changes in web.config  as advised like below

<compilation debug="false" strict="false" explicit="true">


Still, I could not find any difference . Please advise , is there any way to improve the performance of the image manager.
