I have a grid column of button type:
<telerik:GridButtonColumn ButtonType=ImageButton ImageUrl="images/Img_Del.gif"></telerik:GridButtonColumn> I want to tie the button click to a javascript function. Is this possible?
I want to do an AJAX call from this function to perform the delete operation and refresh the grid.
Appreciate a reply.
thanks

Hi
I have a column containing a hashed password, and when the grid is in edit mode,
with the edit form displayed, I don't want the hashed form to appear, just a blank textbox.
I haven't been able to find the right event/method to clear the current content from the
textbox in the edit form, while allowing the new content that is typed in to be bound when
the update takes place.
The column is already a template column.
I am using Q2 2009 on this particular site.
Can you help? (VB preferred)
Thanks
Clive

I'm constructing a User Control called "Hierarchy" inside of which is just one control, a RadTreeView. I load it dynamically and then populate it forthwith. All of that works fine.
With this treeview on the bottom-most nodes have any meaning with a Click event.
What's not working is that if the user clicks a non-bottom node (ie. a branch) then sometimes the treeview remains in the state that it is (good) but other times unexpected things happen with some/all of the branches closing. I'm not sure why this phenomenon is occurring and how I can correct it. Any advice would be much appreciated!
Robert
P.S. An alternative solution would be for me to simply disable the server-side click events of all the branch nodes and only have the click events enabled for the bottom-most nodes. But I don't know if this is even possible or how to do it.

Here is my grid:
Here is the click event:
and down below is the needdatasource method:
The binding occurs and populates the grid when the page loads for the first time. But in the button click event the rebind forces the needdatasource event to fire but does not do any binding with the new passed values.
Please help. Thanks.

Hi all,
I have a grid within an radajaxpanel and I'm looking to update a control in one itemtemplate when a control within another itemtemplate performs a post back (dropdownlist, radiobuttonlist, etc) for that row.
This is not for insert or updating, i'm using the grid for proper formatting. So my question is what event is raised when a control posts back within an item template, and how can I find the control within that row? I've tried adding a handler to the control but it does not fire when the control is within the itemtempate.
Thanks,
John

Greetings,
I am curious as to what I should expect the behavior to be of a page which utilizes a RadAjaxPanel and functions correctly on the dev box (ASP.NET Development Server, VS 2008 .NET 3.5) but it is subsequently deployed to a server that does not have Ajax (AjaxControlTookit etc.) installed or configured properly. Ex. tell would be AjaxControlToolkit.dll not in bin.
As far as I can tell the ajax simply does not work, but the app continues to work correctly as if the ajax panel(s) had never been. Does this make sense? We are using Q3 2009 wihtout SP1 or SP2. This question is specific to RadAjaxPanel, but also could be 100% the same answer behavior as the out of the box UpdatePanel etc. Unfortunately in my build for the day on the server I only have the one spot where postback is not async like I expect it to be (and it is on my localhost). So I can't go check a second page for the same behavior.
On localhost I can see the post data has __ASYNCPOST true, and the param is missing for the autopostback request on the server implicating the default of false. Also RadAJAXControlID parameter is missing in post (for just the real server).
Thank-You,
Justin

I have a setup where I have a masterpage with a codebehind. I have another page that is a web file with a user control + codebehind that uses the master page. On the masterpage I have a RadAjaxManager that I am creating dynamically in the PageInit and adding to a placeholder on the masterpage:
Yet when I run the page none of the ajax works at all. I read in another thread that you should create the radajaxmanager in the PageInit and the updated controls in the PageLoad, I tried this as well to no avail. This is inside the PageLoad:
And this is in the PageInit: (using a proxy because I have a RadAjaxManager on the masterpage for this file)
In both these instances absolutely no ajax works on the page. I used to have these controls on the actual page not in the codebehind and everything worked perfectly.
RadAjaxManager RadAjaxManagerMaster = new RadAjaxManager();
RadAjaxManagerMaster.ID = "RadAjaxManagerMaster";
AjaxSetting RadAjaxManagerMasterAjaxSettings = new AjaxSetting();
RadAjaxManagerMasterAjaxSettings.AjaxControlID = "RadContextMenuMaster"; AjaxUpdatedControl RadWindowAjaxControl = new AjaxUpdatedControl(); RadWindowAjaxControl.ControlID = "RadWindowMaster"; AjaxUpdatedControl RadContextMenuAjaxControl = new AjaxUpdatedControl(); RadContextMenuAjaxControl.ControlID = "RadContextMenuMaster"; RadAjaxManagerMasterAjaxSettings.UpdatedControls.Add(RadWindowAjaxControl); RadAjaxManagerMasterAjaxSettings.UpdatedControls.Add(RadContextMenuAjaxControl); RadAjaxManagerMaster.AjaxSettings.Add(RadAjaxManagerMasterAjaxSettings); RadAjaxLoadingPanel RadAjaxLoadingPanelMaster = new RadAjaxLoadingPanel(); RadAjaxLoadingPanelMaster.ID = "RadAjaxLoadingPanelMaster"; RadAjaxLoadingPanelMaster.BackgroundPosition = AjaxLoadingPanelBackgroundPosition.Center; PlaceHolder PlaceHolderCMSAdmin = (PlaceHolder)Shuware.ShuwareCommon.Web.FindControlByID(this.Controls, "PlaceHolderCMSAdmin"); if (PlaceHolderCMSAdmin != null) { PlaceHolderCMSAdmin.Controls.Add(RadAjaxManagerMaster); PlaceHolderCMSAdmin.Controls.Add(RadAjaxLoadingPanelMaster); }Yet when I run the page none of the ajax works at all. I read in another thread that you should create the radajaxmanager in the PageInit and the updated controls in the PageLoad, I tried this as well to no avail. This is inside the PageLoad:

I have a set of 2 tables I am trying to display in a hierarchical grid.
Table 1 is a list of State Licenses. A rep has an identifying "ProducerNumber" and then a "State", which can appear more than once in the table, plus some other details.
Table 2 is a list of State details. It has the same "ProducerNumber", "State", and then the "Details" line.
So in my table I want the top level grid to be the list of States, and once a state is expanded the Details lines for that state will be displayed underneath. The details lines need to match on 3 qualties: "ProducerNumber", "State", and "Class" to be unique.
I've tried setting my table up as per the sample at: http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/declarativerelations/defaultvb.aspx but I only ever get any details for the top level display. If I click to expand any of the states it's simply blank.
Can anyone help? Are there more examples of how to set this up? Do you need to see my code?

Greetings All,
I am trying to create a MDI (Multiple Document Interface) within an ASP.NET AJAX application using RadMenu and RadWindowManager. I couldn't find anything concerning this topic and wanted to reach out to the community. I have two questions..
1) Is there any documentation about how to achieve this using RadMenu and RadWindowManager? I wasn't able to find any, but don't want to re-invent the wheel if possible.
2) Are there any major flaws with this approach?
(1) Upon creation of a RadWindow...
add a RadMenuItem to the "Window" RadMenuItem using insert() method.
mark the item's state as checked.
mark all other item's state as unchecked.
2) Upon selection of a window's RadMenuItem...
get the corresponding RadWindow and call window.setActive() on the given window.
mark the item's state as checked.
mark all other item's state as unchecked.
3) On window closing...
remove the RadMenuItem for the window using remove() method.
Any feedback is much appreciated.
Regards,
Tom
