I have a grid that I add a dynamic groupby expression that defaults as collapsed and it works fine.
However, whenever I postback the grid doesn't recall the states of which were expanded and
resets all to collapsed. I have seen in the online examples that the grid can retain this information
on postback. The only difference I can notice on the code is that the example is declared in the
ASPX page and mine in code behind. The reason that I do not declare mine in the ASPX page is
because my grid can switch datasources and gets grouped by different columns. Any ideas?
I have seen on here that some people suggest EnableViewState="True" for the grid, however,
isn't it enabled by default? Additionally, in case it matters, my grid is located in an UpdatePanel.
Let me know if anyone has any ideas? Thanks in advance.

Issue with customizing image editor dialogs in IE6

The insert and cancel buttons on the image editor do not display when the image editor is loaded. The user can open and close the upload menu, which will cause the insert and cancel buttons to appear. This seems to be an issue with IE6 when using custom dialogs. I used the standard dialogs that were packaged with the install. I also tried removing the changes that I made to see if it was something that I had changed, but the issue is still occurring

Is there a quick fix that I can add to one of the dialogs to get this to work in IE6?

[Solved] DataSource not found with NestedView

Grid with nested view is reporting the following error when I execute the Insert or Edit command. Without the nested view, Insert and Edit works fine in grdEntities. The nested view portion works fine right now as is(including the user control assocaited with the grdEndorsements). What happens is that when I issue the Insert Command from the grdEntities header or an Edit command from one of the rows in the grdEntities mastertable, I get the following error:

The DataSourceID of 'grdEndorsements' must be the ID of a control of type IDataSource. A control with ID 'SDSGetEndorsements' could not be found.

Here is the code:

    
            <telerik:RadGrid ID="grdEntities" runat="server" Skin="Telerik" 
        
            GridLines="None" AllowPaging="True" AllowSorting="True" Width="99%" AutoGenerateColumns="False"

Item command event

Hi,

I am having this strange set of problem. I am binding the grid at 2 places, once at page load and once when setting a value. Both are calling Grid.Rebind. But Rebind is not firing grid_needDatasource event when called for the second time after pageload. If Iam removinf Grid.Rebind from Pageload, then My item_command event is not being fired. I'll appreciate any solution to this problem

FindControl in Radgrid

Hi,

I am trying to acess a radiobuttonlist which is placed inside a radgrid, so that i can insert its selected value into my database.
I realized that I need to use FindControl, but can't get it to work... the name of my grid is "FichaConteúdo".
I tried:

Control myRadioBtnListTipo = FichaConteúdo.FindControl("RadioBtnListTipo");
sel = myRadioBtnListTipo.SelectedValue;

and also:

Control myRadioBtnListTipo = FichaConteúdo.MasterTableView.Items.FindControl("RadioBtnListTipo");

The problem is that I can't access "SelectedValue", it doesn't appear... I really need the selected value so that I can use it as an sql parameter in my query...
Any suggestions please?

Thank you,
Marta

Unchecking a RadTreeNode with jQuery

Hi There,

I have a RadTreeView (Q2 2008) inside of an UpdatePanel. Also inside the UpdatePanel is a button that deletes all the "checked" nodes.

I'm using jQuery to extend the functionality so that all the child nodes get checked and unchecked with the parent node. If one of the child nodes is unchecked, the parent checkbox is unchecked too (but not the prev and next child checkboxes). I was able to achieve this using the following code:

    
            function pageLoad() { 
        
                    $('.rtChk').bind('click', function() { 
        
                        // Check/uncheck child checkboxes 
        
                        var parentLi = $(this).parents('.rtLI:first'); 
        
                        if ($(this).is(':checked')) 
        
                            $(parentLi).find('.rtChk:not(:first)').attr('checked', true); 
        
                        else 
        
                            $(parentLi).find('.rtChk:not(:first)').attr('checked', false); 
        
                        // Uncheck parent checkbox on uncheck 
        
                        var grandParentLi = $(this).parents('.rtLI:first').parents('.rtLI:first'); 
        
                        if ($(this).is(':checked') == false) 
        
                            $(grandParentLi).find('.rtChk:first').attr('checked', false); 
        
                    }); 
        
                }

This code is working out great and when I uncheck one of the child nodes, the parent appears to be uncheck... however, when I click the button to delete all checked nodes, the parent still gets deleted. I'm thinking that somewhere along the way, the jQuery "uncheck" isn't registering with my asyncronos postback?

I have a RadScriptManager on the page and I've tried registering the script using Page.RegisterStartupScript... but it still doesn't work.

Any suggestions?

[Solved] Disable other commands/drag during ajax postback?

Hi,

I have a raddocklayout with dynamically created zones and docks (inside an updatepanel) that I am using to allow users to edit the layout of their custom web page. I have found that if I don't allow an ajax command to complete (from dock A) before then attempting to drag another dock (B) it seems to recreate dock B in its original location (whilst I still have dock B being dragged) thus creating two copies of B.

I expect this issue would be fixed by preventing any dragging or commands from being executed when an ajax command is being processed. I also wish to prevent the user from clicking on a command twice as they await its execution.

So, my question is if its possible to "disable" all the docks or prevent the docks from being dragged/executing commands when an ajax callback is underway? I assume this would have to be done using javascript as any server side code won't disable the commands/drag functionality until after the postback (and subsequent updatepanel changes have occurred).

I hope that makes sense, let me know if you require further details.

Set CustomFilterColumn CurrentFilterFunction

Below is code that I have for my custom filter column. Everything works great, however, if I select
"All" from the radcombobox I get "No records to display." I am not sure if it is set up correctly to
either remove the the currentfilterfunction and value or how I set the column to no NoFilter when
"All" is chosen. Any ideas? Below is the code. Thanks is advance.
