Insufficient data in bezier chart

Hello,

I'd used bar chart, line chart and bezier chart to show the same data, both of bar chart and line chart were going well, however, when selecting bezier chart, I got the error message shown in the clip, is there any ways to capture error and do some external work to prevent this yellow page?

Regards,

Chart (Obsolete)

Entity framework hierarchical grid

Hello,

I try to use a hierarchical grid using entity-data. Viewing, updating both entities works fine but inserting doesn´t work. I get "Object reference not set to an instance of an object." in " System.Web.UI.WebControls.EntityDataSourceView.ConvertWCProperty(IDictionary values, Dictionary`2 convertedValues, List`1 visitedProperties, PropertyDescriptor pd, ParameterCollection referenceParameters, Dictionary`2& exceptions)"

The last bit with insertParameters is only a guess from my side, seeing others having problems with this using sql but it might not apply to entitys?

I also attached a screenshot of the relevant entities.
Im using asp.net 3.5 sp1 with a mysql-adapter.

Missing Filter menu options

Hi,

I am using the RadGird control to display records. If try filtering the records using the column filters, I get only a handful of filtering options.

I am attaching a snapshot of the problem UI named "Problem UI.jpg" here and an UI working fine named "Proper UI.jpg".

NOTE:
- The problem UI is fetching about 1400 records, whereas the UI working fine is fetching around 20 records.

Any help or suggestions on the issue is highly appreciated.

Thanks

TreeView not Noding... just inline list...

I've taken my data (a list of clients and sub clients)... and converted it to a List<ClientData> where ClientData has three properties: ClientID (int), ParentID (int?), ClientName (string).

Top level clients have ParentID as null. Sub-clients have ParentID set to the ClientID of their parent.

I bind this list to the RadTreeView and get a linear list of all the clients (in proper order), but no "tree view" or "noding" at all. :( Please advise what the heck I'm doing wrong!!!

    
            <telerik:radtreeview id="clientTree" runat="server" skin="Vista" width="100%" showlineimages="true" height="300px" maxdatabinddepth="2">  
        
                        <databindings> 
        
                            <telerik:radtreenodebinding textfield="ClientName" valuefield="ClientID" /> 
        
                        </databindings> 
        
                    </telerik:radtreeview>

    
            ClientTree.DataFieldID = "ClientID";  
        
            ClientTree.DataFieldParentID = "ParentID";  
        
            ClientTree.DataValueField = "ClientID";  
        
            ClientTree.DataTextField = "ClientName";  
        
            ClientTree.DataSource = parsed  (the List<ClientData>)
        
            ClientTree.DataBind();

Grid Rebinds when changing pages

I have a simple grid with paging that displays a few hundred records that are pulled from OnNeedDataSource. There is also a search box at the top of the page that when used retrieves a subset of the records. That all works well.

The issue develops if the search returns enough records that they span more than 1 page. The items that come back are correct and the number of pages are correct but if you click to change pages the grid rebinds and the second page is back to the full record set.

Is there a way to not have the grid rebind on a page switch in this situation?

thanks

[Solved] Upgrade from 4.1.0 to 4.5.6

Hi,
I'm upgrading the RadEditorMOSS solution on my environment from version 4.1.0 to 4.5.6.
There is a problem on the existing instances of the webpart "Telerik RadEditor for MOSS" v.4.1.0 after the upgrade.
They show the error:
Web Part Error: A Web Part or Web Form Control on this Page cannot be displayed or imported. The type could not be found or it is not registered as safe.

Indeed, by adding the files version 4.1.0 to the GAC.
    RadEditor.Net2.dll
    RadEditorSharePoint.dll
    RadSpell.Net2.dll
Plus safe control entries on web.config, it works again.
Is there any way to get the 'old' webparts working correctly with version 4.5.6?

Thanks for the help.

I am working with RadGrid and RadioButton, Dropdown and a RadMaskedTextBox as Columns in a User Control. Dynamically changing the Mask of RadMaskedTextBox according to the items selected in dropdown. But when i am saving the data which is incomplte of the mask (such as (143) 222-3__3) is not giving any validation. So can you please give me your suggestions on this. If any other approaches they are also welcome.

Required Field Validator on GridTextBoxColumnEditor

I have seen the examples for putting a required field validator on textboxes but the same convention does not work for the dropdowns. Here is what we have and we need to get this to work with the dropdown. There isnt a DropDownControl for us to use this with a dropdown as there is with a textbox.

Dim

Service As GridTextBoxColumnEditor = CType(item.EditManager.GetColumnEditor("Service"), GridTextBoxColumnEditor)

Dim YCell As TableCell = CType(Service.TextBoxControl.Parent, TableCell)

Dim rfv1 As New RequiredFieldValidator()

Service.TextBoxControl.ID =

"Service"

rfv1.ControlToValidate = Service.TextBoxControl.ID

rfv1.ErrorMessage =

"Please select a Service"

YCell.Controls.Add(rfv1)

http://www.telerik.com/help/aspnet-ajax/grdvalidation.html (taken from here)

Please let us know what the solution would be for this scenario to change the code above from a textbox to a dropdown. Thanks.

RadGrid: How to create a generic footer format

I am using RadGrid which binds a stored procedure call to 1 DataSet. The first column of the DataSet is "Supervisor" which I have set a grouping on. All of the Supervisors are grouping correctly and works great. However, I would like to add a Footer row to the bottom of each section of Supervisor Groupings. Additionally, I would like to have a summary row for the entire RadGrid at the bottom. I've added the appropriate RadGrid.ShowFooter, RadGrid.MasterTableView.ShowFooter and RadGrid.MasterTableView.ShowGroupFooter values to true.

Finally to my question. For each Supervisor "group" section of data being returned from the stored procedure, I have the Footer summary row with custom calculations performed in the sproc itself. At this point, all I want to do is display the results of that sproc as the Footer. Unfortunately, the data is presumed to be part of the GridDataItems and not a GridFooterItem. How do I configure the sproc and the RadGrid to presume the last row of each "group" is the Footer summary row?

Thanks in advance.
