Displays tree structure symbol eventhough no detail table exists

Hi,

I am using telerik:RadGrid with one master table and 2 detail table in it. On load of the grid if no detail table exists for the row then also it is displaying > symbol. If we click on that then the symbol will go off becuase no details table exists for that row. This was not the problem in the earlier versions of telerik. But now I have upgraded the telerik version to Version=2010.1.413.40. In this version I am getting problem like this.

Is it version problem or can i fix it in my code?

[Solved] RadListView InsertItem Null Values

I have created a RadlistView with the an InsertItemTemplate but when the Insert is carried out the values in the textboxes do not insert into the database. the insert process seems to be working, its just not taking the values from the textboxes.
The delete and edit templates are working great, its just the insert that doesn't seem to work. Would there be any reason for this?
Here is the insert code:

    
            <telerik:RadListView ID="radListView1" DataSourceID="sqlDataSource1" runat="server" 
        
            ItemPlaceholderID="Container" DataKeyNames="ID" AllowPaging="true" 
        
            OnItemCommand="RadListView1_ItemCommand">  
        
            <InsertItemTemplate>  
        
            <fieldset style="float: left; width: 370px; height: 200px;">  
        
            <legend>Name:<asp:TextBox ID="txtBoxName" runat="server" /></legend>

                   <table cellpadding="0" cellspacing="5">

DateTimeColumn filter with DBNulls

Hi

I've developed a web application which relies heavily on the radGrid. Now I've encountered a very serious issue, which I consider a serious bug really.
So ... I've got a grid bound to a datatable (using needDataSource event).
I've got a DateTime column in the grid, which shows a column from the datatable, which is fine up until this point.
Then I've got filtering enabled, which is where my problem lies. If I try to filter on a value (equals), it works like a charm. However if I try 'isNull' or 'isNotNull' things go haywire.
Basically 'isNull' shows everything and the other way around. Basically nothing is null. Why is this?
Well ... I'd say it's because it's not 'null', but 'DBNull'. After all, a datatable built using dataAdapter.fill contains dbnull values instead of regular .net null values.
Of course this is not just limited to this type of column, even a regular bound column with a string value has the same issue. Neither 'isEmpty' nor 'isNull' works.

Anyway, this should really be built into the grid as a grid is used to bind data from a database in 99% of the cases it's used.

The client of course is not happy with this. Can anyone come to my aid here and propose a proper way to make this filter work?

Accessing parent RadGrid's Controls in usercontrol popup

I have a 3-level RadGrid. In the MasterTable (ParentGrid), there's a template column with a label (LocationID). The detailtable(ChildGrid) has a commandItemTemplate "Add Contact". EditMode = popup. The popup is a usercontrol having a RadGrid(radGrid_CompanyContactDetails).

Suppose there are 3 rows in the MasterTable. I click on a row. Then I click on "Add Contact" of the detail table, it opens the popup. Here I want to access the parent Grid's LocationID value for that particular row from the usercontrol's RadGrid's ItemDataBound event. I am able to access the RadGrid if I have the following code:

    
             protected void radGrid_CompanyContactDetails_ItemDataBound(object sender, GridItemEventArgs e) 
        
                { 
        
                    if (e.Item is GridDataItem) 
        
                    { 
        
                        GridDataItem item = (GridDataItem)e.Item; 
        
                        radGrid rGrid = (Telerik.Web.UI.RadGrid)(item.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent); 
        
                        Label location = (Label)rGrid.FindControl("LocationID") // Returns null

            } 
        
                 }

But if I give rGrid.FindControl("LocationID"), it returns null.

Please give some pointers on how to access the parent RadGrid's column values (or controls)

Custom Skins not working with Dynamic Splitters

Hi,
I have made a custom Skin for nested splitters that works OK when I put the splitter code directly in the .aspx page.
When I attempt to create the splitters in C# code-behind with a Link to the skin's css in the .aspx header, the css is not used.
Do I have to dynamically change the skins after the client-side onload event?
Is there another way to specify the Skins css-path in the code-behind?
If so, how would I go about doing so. All your demo's have a "change skin" dropdown (openSkinChooser), but I can't find any info on this.

All this was based in your nested splitters demo and splitters\DynamicObjectCreation (which defaults to the Vista built-in skin)
Here is the code for the .aspx:

RadUpload upload images from local machine

Hi,
I'm using the RadEditor control to allow users to create emails on our website. The website is posted on a webserver, however I want the users to be able to upload images from their own pc's is this possible to do.

My settings are
<telerik:RadEditor ID="RadEditor1" runat="server">
                <ImageManager UploadPaths="~\images" ViewPaths="~\images" />
                <Content>
</Content>
            </telerik:RadEditor>

Can I prevent drag/drop between grids?

I have an application with two RadGrids on the page together. I have drag/drop functionality for each grid, which works fine. However when dragging from one grid to the other, It creates the Javascript errors copied below. On some environments, depending on the version/settings of the browser, it can cause a 404 error. I have tried to solve this issue by adding code to my RowDrop event handler that ignores all drops from other grids. But these errors are happening before the RowDrop is called.

How can I prevent these errors without losing the ability to drag/drop within the same grid?
