Grid column, with two linkbuttons inside

Is there an example, someone can point me to, where I could find out how to add 2 linkbuttons to a single column, rather than having 2 defined columned as linkbutton columns?

Problem with updating grid rating

The code is basicly from the demo example, however, update results in error: ...object reference not set to an instance of an object. any help is appreciated.

VB:

    
            If e.CommandName = "UpdateRating" Then  
        
                            Dim item As GridEditableItem = TryCast(e.Item, GridEditableItem)  
        
                            Dim values As New Hashtable()  
        
                            item.ExtractValues(values)  
        
                            values("ChangeRequestID") = item.GetDataKeyValue("ChangeRequestID")  
        
                            values("Completed") = Int16.Parse(values("Completed"))  
        
                            values("Accepted") = Int16.Parse(values("Accepted"))  
        
                            values("Reviewed") = Int16.Parse(values("Reviewed"))  
        
                            For Each entry As DictionaryEntry In values  
        
                                SqlDataSource1.UpdateParameters(entry.Key.ToString()).DefaultValue = entry.Value.ToString()  
        
                            Next  
        
                            SqlDataSource1.Update()  
        
                        End If

And the grid:

    
            <telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" ShowStatusBar="True"

                        <PagerStyle Mode="Slider" /> 
        
                        <MasterTableView CommandItemDisplay="Top" DataKeyNames="ChangeRequestID" AllowMultiColumnSorting="True" DataSourceID="SqlDataSource1" AllowFilteringByColumn="True">  
        
                            <Columns> 
        
                                <telerik:GridButtonColumn ButtonType="ImageButton" ImageUrl="Images/Update.gif" CommandName="UpdateRating" UniqueName="UpdateColumn" HeaderText="Update" /> 
        
                                <telerik:GridEditCommandColumn ButtonType="ImageButton" EditImageUrl="Images/Edit.gif" HeaderText="Edit" /> 
        
                                <telerik:GridRatingColumn DataField="Accepted" UniqueName="Accepted" Precision="Item" ReadOnly="False" ItemCount="1" HeaderText="Accepted" AllowRatingInViewMode="true" /> 
        
                                <telerik:GridRatingColumn Datafield="Reviewed" UniqueName="Reviewed" Precision="Item" ReadOnly="False" ItemCount="1" HeaderText="Reviewed" AllowRatingInViewMode="true" /> 
        
                                <telerik:GridRatingColumn Datafield="Completed" UniqueName="Completed" Precision="Item" ReadOnly="False" ItemCount="1" HeaderText="Completed" AllowRatingInViewMode="true" /> 
        
                                <telerik:GridRatingColumn Datafield="Priority" UniqueName="Priority" Precision="Item" ReadOnly="false" ItemCount="5" HeaderText="Priority" AllowRatingInViewMode="false" /> 
        
                                <telerik:GridBoundColumn DataField="ChangeRequestID" UniqueName="ChangeRequestID" HeaderText="ID" Visible="false" /> 
        
                            </Columns> 
        
                            <EditFormSettings EditFormType="Template">  
        
                            <EditColumn UniqueName="EditCommandColumn1" /> 
        
                                <FormTemplate> 
        
            ....

And the datasource:

    
            <asp:SqlDataSource ID="SqlDataSource1" DataSourceMode="DataSet" runat="server" ConnectionString="<%$ ConnectionStrings:hldbConnectionString %>" 
        
                          InsertCommand="INSERT INTO ChangeRequestTracker(Accepted, Completed, Reviewed, Priority) VALUES (0, 0, 0, @Priority)"   
        
                          SelectCommand="SELECT * FROM ChangeRequestTracker ORDER BY ChangeRequestID DESC" 
        
                          UpdateCommand="UPDATE ChangeRequestTracker SET Priority=@Priority, Accepted=@Accepted, Reviewed=@Reviewed, Completed=@Completed  WHERE ChangeRequestID = @ChangeRequestID">  
        
                          <UpdateParameters> 
        
                              <asp:Parameter Name="ChangeRequestID"/>  
        
                              <asp:Parameter Name="Priority"/>

RadGrid Simple Binding

Hi buddies!

I'm facing a little problem with the RadGrid control.

I've got a simple RadGrid:

    
             <telerik:RadGrid ID="RadGrid1" runat="server"   OnNeedDataSource="RadGrid1_NeedDataSource"> 
        
                </telerik:RadGrid>

When i use this code eveything works and the data is well displayed :

    
             Protected Sub RadGrid1_NeedDataSource(ByVal [source] As Object, _ 
        
                     ByVal e As GridNeedDataSourceEventArgs) _ 
        
                     Handles RadGrid1.NeedDataSource 
        
                    Dim list As New ArrayList 
        
                    list.Add("string1") 
        
                    list.Add("string2") 
        
                    list.Add("string3") 
        
                    RadGrid1.DataSource = list 
        
                End Sub

But when i try to use a custom class (Acontact) this is the class :

    
            Public Class AContact 
        
                Private _name As String 
        
                Private _email As String 
        
                Public Property Name() As String 
        
                    Get 
        
                        Return _name 
        
                    End Get 
        
                    Set(ByVal value As String) 
        
                        _name = Name 
        
                    End Set 
        
                End Property 
        
                Public Property Email() As String 
        
                    Get 
        
                        Return _email 
        
                    End Get 
        
                    Set(ByVal value As String) 
        
                        _email = Email 
        
                    End Set 
        
                End Property 
        
            End Class

i try this, but the grid stays empty:

    
            Protected Sub RadGrid1_NeedDataSource(ByVal [source] As Object, _ 
        
                     ByVal e As GridNeedDataSourceEventArgs) _ 
        
                     Handles RadGrid1.NeedDataSource 
        
                    Dim maListe As New List(Of SABerni.Gateway.AContact) 
        
                    Dim Contact1 As New SABerni.Gateway.AContact 
        
                    Contact1.Name = "demo" 
        
                    Contact1.Email = "emaildemo" 
        
                    maListe.Add(Contact1) 
        
                    RadGrid1.DataSource = maListe 
        
                End Sub

Does anybody have an idea? Thanks a lot..

Multi row selection in grouped grid (or hierarchical grid)

Hi,

I need to implement several level nested hierarchy with possibility to check (or select) multiple rows, but also whole groups or sub-groups of rows (let say that for rows of orders for customers from different countries I need to group every orders of each customer together and every customers from each country together and then be able to select multiple orders – one by one or every for selected customers or every for selected country – so that after selecting one subgroup, each row of this sub-group will be selected).

I would like to use grouping for this – but I was not able to simply add check-boxes in header lines.

<telerik:GridGroupByExpression>

<telerik:GridGroupByField FieldName="countryName" HeaderText=" <input type='checkbox' onClick='CountryRowSelecting()'> " />

</SelectFields>

<telerik:GridGroupByField FieldName="countryId" SortOrder="Descending" HeaderText="Country" />

</GroupByFields>

</telerik:GridGroupByExpression>

<telerik:GridGroupByExpression>

<telerik:GridGroupByField FieldName="customerName" HeaderText=" <input type='checkbox' onClick='CustomerRowSelecting()'> " />

</SelectFields>

<telerik:GridGroupByField FieldName="customerId" SortOrder="Descending" HeaderText="Customer" />

</GroupByFields>

</telerik:GridGroupByExpression>

But then I was not able to properly handle these events, I think there should be some easier way.

I was also trying hierarchical grid (but I would like it with grouping more), but there with multi-rows grouping, when I selected whole category, just one sub-level subcategories was selected (but I need it for each level- e.g. after selecting some country, each order for each customer from this country would be selected).

Does radgrid somehow enable this desired behaving?

Thanks

Jan

Hovering Images in Rotator

I have a rotator within a user control. The content size of the screen is being set via JavaScript with scroll bars turned on. The browser scroll bars are turned off so not to confuse the user with two sets. The images within the rotator work just fine except for one major issue. The image “hovers” over the page and does not position itself within the rotator. Only when the browser scroll bars are active and the content scroll bars are turned off does the image behave correctly. Attached is the code and any assistance would be greatly appreciated.

    
            <telerik:RadRotator ID="thumbRotator" runat="server" RotatorType="ButtonsOver" Height="120px" Width="600px" ItemHeight="120px" ItemWidth="150px" FrameDuration="1" ScrollDuration="500" ScrollDirection="Left,Right" EnableEmbeddedSkins="false" OnItemClick="ShowImage">  
        
            <ItemTemplate> 
        
            <div style="text-align:center; padding:20px;">  
        
            <asp:Image ID="imgRotator" runat="server" Height="50px" Width="50px" ImageUrl='<%# DataBinder.Eval(Container.DataItem,"Source") %>' /> 
        
            <br /> 
        
            <%# DataBinder.Eval(Container.DataItem, "TypeDescription")%> 
        
            <br /> 
        
            (<%# DataBinder.Eval(Container.DataItem, "Size")%>)  
        
            </div> 
        
            </ItemTemplate> 
        
            <ControlButtons LeftButtonID="img_left" RightButtonID="img_right" /> 
        
            </telerik:RadRotator>

scroll to selected node in tree view inside of custom edit form of grid

I have a grid with a custom edit form with a tree view. When the custom edit form is loaded, the tree nodes are programatically created based on the grid row being edited. I also programatically select a node based on the grid row being edited. I need to have the tree view scrolled to the selected node when the edit form loads. I'm trying to implement the "selectedNode.scrollIntoView();" method, but I'm having trouble "finding" the tree view from the page that has the grid. Suggestions on how this can be accomplished?

Get corresponding Tab ID from user control

Hi

I'm implementing the TabStrip with RadMultipage. Each of the user controls has a grid which is refreshed with a timer. What I want to be able to do is turn off the relavent timers when I change the tab.

I hope this makes sense, I suppose the minimum I need is how to identify which tab was clicked from the user control (ascx page)

Access File Share from Hyperlink Column

Hi all (and thanks in advnace for your help),

I have a hyperlink set as follows:

    
            <asp:HyperLink  
        
            ID="HyperLink1" 
        
            runat="server" 
        
            NavigateUrl = "\\server\share\SomeDoc.doc>  
        
            </asp:HyperLink>

This works fine & is what the client wants. It opens the file "SomeDoc.doc" in MS Word.

Now the question. I have a table as follows:

    
            "John", "\\server\share\John.doc" 
        
            "Mary", "\\server\share\Mary.doc" 
        
            etc...

I would like to use th RadGrid control with a HyperLink column so that the NavigateUrl is set to the UNC Path of the file in the table so when the user clicks the Hyperlink, the file "\\server\share\John.doc" opens up in MS Word.

I am have difficulty doing this.

Any ideas would be greatly appreciated.

Thanks, Kevin

Captcha - Grey Box in Firefox

I'm using a single Windows 2008 server - not a web farm environment. When I implement the captcha control in my application, everything works flawlessly in Internet Explorer (all versions). However, when viewing my form in Firefox, sometimes all I get is a grey box. When I click "Refresh Image", nothing happens. This is only an issue in Firefox.

I have pasted the code control and parameters below, and have also attached a screenshot of the CAPTCHA properties window. Please let me know of any other information you need from me to troubleshoot.

Thank you.

<telerik:RadCaptcha ID="RadCaptcha1" Runat="server" ErrorMessage="You have entered an invalid code"
ValidationGroup="Group" EnableRefreshImage="True"></telerik:RadCaptcha>
