Tool tip not displaying in RadGrid GridHeaderItem

Posted 52 minutes ago (permalink)

Hi,

I am learning the RADGrid control. The following code of page 459 does not work:

    
            imports Telerik.WebControls  
        
            Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As  
        
            Telerik.WebControls.GridItemEventArgs)  
        
            'Check for GridHeaderItem if you wish tooltips only for the header cells  
        
            If TypeOf e.Item Is GridHeaderItem Then  
        
            Dim headerItem As GridHeaderItem = TryCast(e.Item, GridHeaderItem)  
        
            headerItem("CreditRating").ToolTip = "CreditRating" 
        
            headerItem("PreferredVendorStatus").ToolTip = "PreferredVendorStatus" 
        
            headerItem("ActiveFlag").ToolTip = "ActiveFlag" 
        
            End If  
        
            End Sub

First, there's a problem with the namespace. There is a squiggly line under the namespace explained as follows:

"Namespace or type specified in the Imports 'Telerik,WebControls' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public memeber. Make sure the imported element name doesn't use any aliases."

So I guess that means that 'WebControls' is not a member of Telerik?

Next, Type 'GridHeaderItem' is not defined.

I deleted the 'Telerik.WebControls' namespace and used the 'Telerik.Web.UI' namespace. I revised the code to:

    
            Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs)  
        
                    'Check for GridHeaderItem if you wish tooltips only for the header cells     
        
                    If TypeOf e.Item Is GridHeaderItem Then  
        
                        Dim headerItem As GridHeaderItem = TryCast(e.Item, GridHeaderItem)  
        
                        headerItem("CreditRating").ToolTip = "CreditRating" 
        
                        headerItem("PreferredVendorStatus").ToolTip = "PreferredVendorStatus" 
        
                        headerItem("ActiveFlag").ToolTip = "ActiveFlag" 
        
                    End If  
        
                End Sub

The application ran, but I can not see the Tool tips. Is there a correction written somewhere for this?

Thanks!

Filter not Filtering

Filtering not working on simple databind. Even when the filter tries to display it doesn't even show the no records template. Code below.

Enhanced RadComboBox (Web Service Templates, Paging, Multi-Select with CheckBoxes, etc.,) - contributing source back to RadComboBox

While outsourcing for a company (who has licenses for Telerik's Ajax components) I did some research on RadComboBox and some enhancement of its functionality to support Paging, Multi-select (using checkboxes & mouse dragging), limit list by "show selected only", "select all", item templates on Web Service calls, Sorting, etc.

Now that my term is now due with them, given that some of the work I did was "hacks" into the client-side javascript code and I'm concerned that newer versions will override my work (causing the customer to have to do some more "hacking"), I was wondering whether it was possible to share some of this work with Telerik so that some of the features will (hopefully) be part of the upcoming versions of the components.

See ComboBox1 Image for RadComboBox with Multi-select with dragging of mouse, paging.
See ComboBox2 Image for same RadComboBox with multiple items selected, showing in Tooltip the items that were selected.
See ComboBox3 Image for same RadComboBox, all items selected, with Hay skin.

All of the above use Web Service with Item Templates.

Databinding in a formView.. programmatically

hi there.. I am a little confused on how/why some of my ctrls are able to use the SelectedValue = '<%# Bind() %>' and some are not.

The one that can bind is using an ObjectDataSource within the ascx:

    
            <telerik:RadComboBox ID="ComboDepartment" runat="server"   
        
            DataSourceID="CCentres" DataTextField="CC_desc"   
        
            DataValueField="CC_desc" SelectedValue='<%# Bind("department") %>'>   
        
            <CollapseAnimation Duration="200" Type="OutQuint" />   
        
            </telerik:RadComboBox> 
        
            <asp:ObjectDataSource ID="CCentres" runat="server" SelectMethod="GetData" TypeName="CC2TableAdapters.Cost_centresTableAdapter">   
        
            <SelectParameters>   
        
            <asp:SessionParameter DefaultValue="1" Name="Empid" SessionField="empid" Type="String" />   
        
            </SelectParameters>   
        
            </asp:ObjectDataSource>

the one that is not working is the following

    
            <telerik:RadComboBox ID="ComboStatus" SelectedValue='<%#Bind("status") %>' runat="server">   
        
            <CollapseAnimation Duration="200" Type="OutQuint" />   
        
             </telerik:RadComboBox>

the combo status is being built using the following code from within the formview_onload Event.

    
            Protected Sub FormView1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.Load  
        
             If FormView1.CurrentMode = FormViewMode.Insert And Not IsPostBack Then  
        
            Dim Status As RadComboBox = FormView1.FindControl("ComboStatus")  
        
            Status.DataSource = functions.NameValues("status")  
        
            Status.Items.Add(New RadComboBoxItem("Select"))  
        
            Status.AppendDataBoundItems = True 
        
            Status.DataTextField = "Name" 
        
            Status.DataValueField = "Value" 
        
            Status.DataBind()  
        
            end if  
        
            End Sub

My preference is to populate the boxes from code but still them bound to the formview.. is this possible?
thanks
mac

DataBind() method keeps resetting my DataGroupColumn

Like
DataGroupColumn -= *function to get group column*, group column returns EmployeeID

But after the DataBind() event, the DataGroupColumn becomes OrderID, (OrderID was the first column in the datatable).

RadGrid Custom Skin Check Mark

I've successfully created custom skins for the RadGrid and Panel controls by following the great examples provided.

However, I can't seem to find any way to change the color/image of the green check mark in various controls such as the RadGrid select columns.

If anyone could provide an example, I'd appreciate it.

Cannot see all nodes with GetAllNodes()

Hi

Based on your example I add nodes to my RadTreeView on demand when clicking expand node. And this looks great. But later i use GetAllNodes on my RadTreeView and it only loads the 3 first nodes. When i debug my add function and observing the RadTreeView it does not seem to grow though I see the new nodes on the webpage.

So it seems like I only add the nodes visually??
