Adding hyperlink to grid column at runtime

Hello, I have RadGrid which is populated from a data table and the columns for the grid are Autogenerated...since business logic prevents me from defining a telerik:GridHyperLinkColumn at design time how can I add a Hyperlink to a column that was auto generated. I would like it to appear like a design time telerik:GridHyperLinkColumn column where the columns data's text is hyperlinked I also trap the grids ItemDataBound event and build the hyperlink dynamically using the data from other columns in the grid.

Thanks

RadGrid with Insert/Update/Delete and bind the combo

Hi Telerik,

I have a radgrid with items say(Problem name, start_date, end_date, comments). The grid binds by joining two queries becoz in my table structure one table contains the Problem name and Problem Id (let's say <table_problem>) and another one with start_date, end_date and comments(let's say <table_date>) etc. I bind the grid by joining these two tables. When I double click on grid it would expand the record in edit mode and in edit mode the problem name should be dropdown and all others are textbox and the problem name should bind with problem id and problem name. So here I am unable to bind the dropdown. What ever the queries required for this table should insert/update/delete record in these two tables. So please help me. How to bind the dropdown and all other controls in edit mode.

This is very urgent. Please reply me soon.

Thanks,

Monalisa

Dynamic resource filtering in Insert/Edit Template

Hello

In my AdvancedInsertTemplate i have :

    
            <tr> 
        
             <td> 
        
              <asp:Label ID="Label2" AssociatedControlID="CB_Groupe" runat="server" CssClass="inline-label">Groupe :</asp:Label> 
        
             </td> 
        
             <td> 
        
              <telerik:RadComboBox runat="server" ID="CB_Groupe" DataTextField="Text" DataValueField="Key" 
        
                Width="230px" Skin="Black" SelectedValue='<%# Bind("GroupeID") %>' 
        
                DataSource="<%# GetAvailableUsers(Container) %>"> 
        
              </telerik:RadComboBox> 
        
             </td> 
        
            </tr> 
        
            <tr> 
        
             <td> 
        
              <asp:Label ID="Label5" AssociatedControlID="CB_Forfait" runat="server" CssClass="inline-label">Formule :</asp:Label> 
        
             </td> 
        
             <td> 
        
              <telerik:RadComboBox runat="server" ID="CB_Forfait" DataSourceID="ForfaitsDataSource" 

                DataTextField="FormuleComplete" DataValueField="comptes_groupes_id" Width="230px" Skin="Black"

                SelectedValue='<%# Bind("ForfaitID") %>'> 
        
              </telerik:RadComboBox> 
        
             </td> 
        
            </tr>

When i want to add a control parameter on the ForfaitsDataSource (AccessDataSource). I haven't the access to the control because the control is in the AdvancedInsertTemplate.

    
            <asp:AccessDataSource runat="server" ID="GroupesDataSource" DataFile="~/App_Data/bdd.mdb" 
        
              SelectCommand="SELECT * FROM [groupes]"> 
        
            </asp:AccessDataSource> 
        
            <asp:AccessDataSource runat="server" ID="StudiosDataSource" DataFile="~/App_Data/bdd.mdb" 
        
              SelectCommand="SELECT * FROM [studios] ORDER BY [Ordre]"></asp:AccessDataSource> 
        
            <asp:AccessDataSource runat="server" ID="ForfaitsDataSource" DataFile="~/App_Data/bdd.mdb" 
        
              SelectCommand="SELECT [comptes_groupes_id], [id_groupe], [id_tarif], [nb_heures_restantes], [Studio]&', '& [duree]&'h, Backline : '&[comptes_groupes].[backline]&' , '& [nb_heures_restantes]&'h restante(s)' as [FormuleComplete]  from [comptes_groupes], [tarifs_studios], [studios] where [id_tarif] = [tarifs_studios_id] and [studios].[id] = [id_studio]"> 
        
             <SelectParameters> 
        
               (ControlParameter here ?) 
        
             </SelectParameters> 
        
            </asp:AccessDataSource>

I want, when the id_groupe is changed, the ForfaitsDataSource filter the SQL request (in the ForfaitsDataSource SelectCommand : "(...) AND id_groupe = (id_groupe selected in the control)" )

Any ideas ?

Thanks in advance :)

My scenario has two types, 'Type2' and 'Type3', that extends from 'Type1'. I'm trying to set a 'Type1' list with 'Type2' and 'Type3' objects as a DataSource to grid and i'm getting the following exception message:

"Unable to cast object of type 'Type2' to type 'Type3'."

Is this a bug or i missed something ?

Thanks.

Label on masterpage

Hi,

I have a masterpage application.
On the masterpage I have 2 asp:Label controls.
In codebehind (page load) I set them to a session variable.
So if in a contentpage is something to tell on the master - I just set that session variable.

Now my problem - when I work with ajax manager I thought that this would be the right setting:

    
            <telerik:RadAjaxManager ID="ramManager" runat="server" DefaultLoadingPanelID="alpPan1" UpdatePanelsRenderMode="Inline" RequestQueueSize="6">  
        
                <AjaxSettings> 
        
                    <telerik:AjaxSetting AjaxControlID="ramManager">  
        
                        <UpdatedControls> 
        
                        <telerik:AjaxUpdatedControl ControlID="lblOne" /> 
        
                        <telerik:AjaxUpdatedControl ControlID="lblTwo" /> 
        
                        </UpdatedControls> 
        
                    </telerik:AjaxSetting> 
        
                </AjaxSettings> 
        
            </telerik:RadAjaxManager>

But this results in a "the controls collection can't be changed..." error.
I have nothing on my content page so the code above produces this problem.

Any idea how I can achive this?
This == two labels displaying information (from session state) on the masterpage

Regards

Manfred

[Solved] OnDemand load nodes with HierarchicalDataSource

Hi,

With my problem of CommandButton in node loaded serverside with a callback, I had to code a HierarchicalDataSource.

But the problem is that page load time is very long since the treeview loads all nodes. I have about 10000 nodes, it take 5s to load (localhost) but long long time to execute javascript onload codes. Maybe caused by RadFormDecorator...

Anyway, is there a way to improve RadTreeView working with HierarchicalDataSource to have nodes populated on-demand, with serverside callbacks, and with rendered template controls persistance for event handling ?
It can let users add their own UserControls to a node, thus allowing non-common usages of a treeview...

Thanks.
