UPDATE: Decided just to use session variables to track the state and that works.

Hello,
For the past two days I have been having a difficult time with a particular issue related to selecting or binding the selected value in a RadComboBox within a custom grid edit template column that I cannot find examples for exactly and have not been able to get the scenario to work.

Scenario
There is a 100% programmatically created RadGrid where the columns are dynamically created.  There is a GridTemplateColumn that can be created with a custom item template and edit template.  The item template is relatively simple with just a literal control in it, while the edit template has a RadComboBox.  The reason a GridDropDownColumn is not utilized is that the items in the RadComboBox contain localized text based on the user's context/language and this cannot be determined through a DataSourceID. When the user edits a row they see the correct items populated in the RadComboBox for that particular template and column, and the item template reflects their change (e.g. if they selected "Female" from the RadComboBox and save/insert their change they see the text "Female" in the item/non-edit tample).  However when they edit a row after inserting the value the RadComboBox does not select the value they previously entered as the selected value. 

Issue
The issue is that I cannot seem to find a way to bind the RadComboBox within the EditTemplate's selected value to the matching value from the text/item template.  Every time the user clicks edit (the edit mode is PopUp) all the regular column values get set to the same values they were in read/non-edit mode, except the RadComboBox in the custom edit column template.

Maybe in the RadGrid's ItemDataBound event there is a way to get the value from the the label control in the item template and use that to set (or try to find then set) the selected value in the RadComboBox in the edit template?  Or maybe i'm missing something crucial to the process.

Please note I utilized the converter at http://converter.telerik.com to convert VB.NET to C# since most people are working in C#.  The converter sometimes does not convert things exactly.





This is the setup specific to this type of column, assume the column unique name, etc. have already been set.

Edit Template: 

Item Template: 


I want to do this without using Session variables.  It seems really "hacky" to utilize them to store the drop down/combobox's selected state.  Also imagine the case, where there are 20 rows of data in the RadGrid with multiple columns in each row that could be of this EditTemplate type with the dropdons, there are quite a few session variables that would be around just to track the selected state and they'd stick around until session expiration unless they are explicitly removed.

Hi,

I am putting DataSource of RadGrid into a Session and when I've to re-bind the RadGrid I want to use the Session. I tried by using the following code.

Binding the RdaGrid for the first time,

  var mentors = (dynamicModuleManager.GetDataItems(mentorType)).Where(i => i.Visible == true &&
                i.Status == ContentLifecycleStatus.Live &&
                (i.GetValue<IList<Guid>>("mentorshipcategories").Any(j => CategoriesChecked.Contains(j)) ||
                i.GetValue<IList<Guid>>("industries").Any(j => CategoriesChecked.Contains(j)) ||
                i.GetValue<IList<Guid>>("businessstages").Any(j => CategoriesChecked.Contains(j))));


            MentorDetailsGrid.DataSource = mentors;
            MentorDetailsGrid.DataBind();
            Session["TempMentorsResult"] = mentors;

So ultimately mentors variable is of type IQueryable<DynamicContent>.

Now while rebinding the RadGrid, here are the lines used,

 MentorDetailsGrid.DataSource= Session["TempMentorsResult"];
                MentorDetailsGrid.DataBind(); //At this point I am getting the run-time error  

The ObjectScope has already been disposed and it's managed persistent objects can no longer be accessed. The ObjectScope should be disposed at the end of the life cycle of your business logic instance. This can also be done in the Dispose of your ASP page or MVC controller.
Object name: 'OpenAccessRuntime.EnlistableObjectScope'.

Can someone please tell me where I am doing wrong?

Thanks.

I'm working on a project for a client, where the app I'm building will serve to edit an XML file consumed by a live application. The application is written in Flash, and quite unstable, so I am kind of stuck with the less than optimal XML setup.

The XML is made up (simplified) like the following:

 

 

I've been using a Telerik treeview bound to an XMLDataSource to display the data and allow users to interact with it (add/delete nodes, move nodes by means of drag and drop, or copy nodes and the underlying elements). So far, so good.

Now my client would like to know if it is somehow possible to use the <Type> Element of the Item elements as grouping containers.

So currently the treeview looks like this:

category1
--Category1Item1
--Category1Item2

And ideally, it should end up looking like this:

category1
--Wood
----Category1Item1
----Category1Item123
--Stone
----Category1Item2
----Category1Item456

 

I read up on HierarchicalDataTemnplates, but have not managed to figure out if these work in the ASP.NET controls supplied by Telerik. I would like to try and stick to what I have so far, as many hours of work have already gone into the product so far.

I'd appreciate it if someone could point me in the right direction of how to tackle this particular issue.

Thanks in advance :)

HI,
I am using TimeLine view on RadSchedular. Following is the code. time duration slot is for 2 Week.
I want to show column header as ( Week Start date- Week End date) . example - 05/31/2012 - 06/13/2012.
See attachment also. Is it possible to do that?

I trying to bind the orgChart to a large dataset and doesn't seem to work. The dataset contains about 150000 rows. I am using the latest Q2 Beta.
<telerik:RadOrgChart ID="RadOrgChart1" runat="server" EnableCollapsing="true" LoadOnDemand="NodesAndGroups" Skin="Office2010Blue">

 </telerik:RadOrgChart>

 

 protected void Page_Load(object sender, EventArgs e)
    {
        BindToDataSet(this.RadOrgChart1);
    }

    private static void BindToDataSet(RadOrgChart orgChart)
    {
        string dbConnectionString = ConfigurationManager.ConnectionStrings["mambophilprod"].ConnectionString;
        MySqlDataAdapter adapter = new MySqlDataAdapter("SELECT Id, ParentId, CurrentPosition From mambophil_flat_tree",
                                                    dbConnectionString);

        DataSet links = new DataSet();
        adapter.Fill(links);

        orgChart.DataTextField = "CurrentPosition";
        orgChart.DataFieldID = "Id";
        orgChart.DataFieldParentID = "ParentID";

        orgChart.DataSource = links;
        orgChart.DataBind();
    }

This is what I would like to do.
- I want to show the first few levels (say 10)
- When the user clicks on one of the last levels, the system fetches the next 10 levels.

Is this possible? Appreciate your help.

I have a radscheduler that currently shows multi-day appointments on the start date with a small arrow indicating that it spans multiple days, however, i would like the appointment block to actually span the multiple days.
