I have an ASP DetailsView with a RadGrid in one of the Template Columns. What I would like to do is when I put my DetailsView into edit mode to add the edit and delete columns to the RadGrid. Right now I have it so in the DataBound event for the DetailsView I check if it's in edit mode and then add the "Add New Record" button. I have tried adding code to turn on the edit column but it doesn't work. See the code example below. Any help would be appreciated.

Hi everyone,

I am having a problem refreshing a node after saving changes on the server side.  A summary:

I have an ASP.NET Ajax RadTreeView within an UpdatePanel.  A user selects a node and clicks an Edit button.  This opens a jQuery dialog in which node data can be changed, such as the description (not the value!).  After clicking the Save button in the dialog, a piece of JavaScript triggers a button, which has been registered for AsyncPostBack.  On the server side, the node data is saved, and execution returns to a JavaScript method on the page.  I then want to refresh the node that has been edited, in order to display, for instance, the new description for the node.  I might be going about this the wrong way, but I thought I would be able to accomplish this by refreshing the node's parent, and then re-selecting the node itself.  Everything works, accept re-selecting the node that had been edited. 

I write the following code:

var tree = FindTree();
var currentNodeValue = tree.get_selectedNode().get_value();
RefreshParentNode();
var currentNode = tree.findNodeByValue(currentNodeValue);
// TODO: why is this node not found?!?
// For now, after update, the parent is selected because the child node is not found, even though it is there...
if (currentNode) {
    currentNode.select();
}

The RefreshParentNode function simply finds the parent node of the selected node, and then refreshes it using the following code:

function RefreshNode(node) {
    if (node) {
        node.collapse();
        node.get_treeView().trackChanges();
        node.get_nodes().clear();
        node.set_expandMode(Telerik.Web.UI.TreeNodeExpandMode.WebService);
        node.get_treeView().commitChanges();
        node.expand();
    }
}

All nodes are now displayed correctly, including the updated node with its new description.  However, as the comments in the code fragment at the top show, the findNodeByValue function fails to find the node that had been edited, so I can't re-select it.

So, I basically, have two questions:

1) Is there an easier way to get the edited node to display its new description?
2) If not: why is the node not found by findNodeByValue after refreshing the parent, and how can I fix this?

By the way, in case this is not clear from the code fragments above: I am using a LoadOnDemand scenario.  Root nodes are loaded immediately, child nodes are loaded using a webservice.

UPDATE: Yes, the FindTree method uses $find and not $get.  The tree reference is not the problem...

I have a radgrid with a radbuttons added to the master table view. And I want to use tooltip manager and add tooltips from the database dynamically. Can any one tell me how to add tooltips step by step . This is my radgrid code. Please help Me!

 

Do you have to have a DataSource defined in the .aspx for htis to work ? 

What i was doing initially was databinding a list to my combobox in the code behind (page load)

I'm trying to get this working with automaticloadondemand but failing. 

I've tried adding it into itemsrequested as well but no luck. I was hoping i'd be able to do this automatically rather than have to handle the request each time and have to calculate how many items are returned and what other ones need to display (showmoreresults box)

etc etc.

Hi,

I am using RadAjaxPanel in my DotNetNuke Application, I'm trying to do a RadAjaxPanel ajaxRequest (invoked on the client) to call the server event-handler. I do have a server-side AjaxRequest handler defined but it never gets call because of something with the request. What do I have to do to figure this out?

Please Help Me !!!

Thanks in advance for your help

Here is another issue with Telerik Control. Following is the scenario:

 

We have three panels on the form which is Ajax enabled:

1.       Panel 1 – where user enters information.

2.       Panel 2 – where user uploads document using Telerik RADAsyncUpload control.

3.       Panel 3 -  where user confirms his information and uploaded files before he submits.

 

Issue:                                      

 

The user has the option to go back and forth between above three panels to update any information. But the problem arises when user selects files in Telerik RADAsyncUpload control and he goes back to the Panel 1 and Comes back to the Panel 2 (or from Panel 3 to Panel 2). The files that the user is selected are lost. The telerik upload control doesn’t maintain the state of the selected files. Instead it goes back to the initial state.

 

We tried to use the “PostbackTriggers” property but it is not working.

 

Please assist us asap.

Thanks.

Hi,

I have a radpanelbar in a RadAjaxUpdate panel . I need to post back the page when i click or expand  the radpanel item . But got an error.
System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).    at System.Web.UI.ControlCollection.AddAt(Int32 index, Control child)     at Telerik.Web.UI.RadAjaxControl.MoveUpdatePanel(Control initiator, Control updated)   

I have the following code

I have a radtextbox on an aspx page that renders correctly on all major desktop browsers. On the IPad with the latest browser it draws the top half of the textbox only. I can click in the textbox and it will redraw correctly, but on form load I get the top half only. Is this a known issue corrected with upgrades to the IPad browser or Telerik controls?

I am using v. 2011.2.712.40

Thanks,
Ben
