[Solved] RadComboBoxItem not detecting selected checkboxes in checkbox template

Hello,

I have a RadComboBox with a multi-checkbox setup. It is working fine but when try loop through the items and see if anything has been selected it is showing FALSE even when I have definitely selected some items.

My code is as follows:

    
            foreach (RadComboBoxItem rcbi in cmbAccessories.Items) 
        
            { 
        
                 if (rcbi.Selected) 
        
                 { 
        
                     //insert value in database 
        
                 } 
        
            }

    
            <telerik:RadComboBox ID="cmbAccessories" Width="200px"  
        
                                            OnClientDropDownOpening="OnClientDropDownOpening"  
        
                                            EmptyMessage="...Select Accessories"  
        
                                            OnClientDropDownClosing="OnClientDropDownClosing"  
        
                                            OnClientSelectedIndexChanging="OnClientSelectedIndexChanging"  
        
                                            OnClientBlur="OnClientBlur" DataTextField="Name" DataValueField="AccessoryID"  
        
                                            ValidationGroup="valItem" HighlightTemplatedItems="false"  
        
                                            AllowCustomText="True" Runat="server" ShowDropDownOnTextboxClick="False"  
        
                                            EnableTextSelection="False"> 
        
                                            <ItemTemplate> 
        
                                                <asp:CheckBox ID="chkBox" Text='<%#Eval("Name") %>' onclick="checkboxClick();" runat="server" /> 
        
                                            </ItemTemplate>                                 
        
                                            <FooterTemplate> 
        
                                                <div style="width:100%;" align="center"><asp:Label ID="lblCloseMe" Text="CLOSE [X]" onclick="CloseMe();" style="cursor:pointer;" runat="server" /></div> 
        
                                            </FooterTemplate> 
        
                                        </telerik:RadComboBox>

Radgrid export to CSV for dynamic GridTemplateColumn

Hi,

I have a grid with many GridBoundColumns and one GridTemplateColumn. The GridTemplateColumn has a ItemTemplate which is generated dynamically from code-behind. I have a place holder in the ItemTemplate in which a table is added programmatically.

<asp:placeholder id="DetailPlaceHolder" runat="server"></asp:placeholder>

</ItemTemplate>

The table for each row in the Radgrid is added to the placeholder in the OnItemDataBound event. The grid displays the data in the perfect manner as desired.However, my export functions are not including the dynamically generated tables. All the export functions ExportToExcel, ExportToCSV, ExportToWord donot include the dynamically generated table in the GridTemplateColumn. I can get the excel and word to work by making the ExportOnlyData="false", but then also my ExportToCSV is not working. Can anyone please tell me how to solve this problem ??

[Solved] How do I turn off AddNew

Under certain circumstances I may wish to remove the ability for a user to add a new item to the grid.

e.g.

User adds clicks:
<CommandItemSettings
AddNewRecordText="Click here to add new item"

After clicking save\update and certain conditions are met I wish to block the user from being able to add any more items. Ideally I would like to set AddNewRecordText = ""
AddNewRecordImageUrl = "spacer.gif" to hide it

Is there a property I can set to say AddNew.Enabled = false or something similar.

This is a hierarchical grid and I do not wish to prevent the user from continuing to add items to the detail grid. Only the Master should be disabled.

Optimization and viewstate = false

I am watching your webinar on grid optimization, and one of the recommended techniques is to disable viewstate on all read only grids.
I have several grids that are read only, but that use:

    
            <telerik:GridButtonColumn ButtonType="ImageButton" ImageUrl="~/images/icon_page_magnify.gif" HeaderText="Select" UniqueName="Select" CommandName="Select" />

and an OnItemCommand, which is causing an invalid postback problem.
I realize this is a limitation in .Net, but is there some other way to create a grid navigation activity that sets a session variable and redirects to a different page that would allow me to keep the viewstate off?

I am just trying to find some other way to achieve this result while still being able to leave the viewstate off.

The onItemCommand is this:

    
                        if (e.CommandName.ToUpper() == "SELECT")  
        
                        {  
        
                            Session["A"] = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["A"];  
        
                            Response.Redirect("~/Item/");  
        
                        }

Or maybe I don't need a session variable, how else could i send the user to another page with an id without using the query string???

[Solved] How to bind to a RadTreeview

Hi,
I have a query (CTE) that returns the parent child relationship in a dataset and I can bind to an ASP.Net treeview but I want to be able to bind to a RadTreeView. Can anyone help me with the conversion?
Here's my code to bind to a treeview:

    
             Private Sub InitializeControls()  
        
                    '==Get some info from the logged in user  
        
                    Dim oContact As New Contact(UserInstance.ContactID)  
        
                    '== Labels  
        
                    lblDownline.Text = "My Distributor Downline" 
        
                    LoadDataSet()  
        
                    '== If it's the root node, SponsorID will be zero so use their contactid  
        
                    Dim parentID As Integer = 0  
        
                    If oContact.SponsorID = 0 Then 
        
                        parentID = UserInstance.ContactID  
        
                    Else 
        
                        parentID = oContact.SponsorID  
        
                    End If 
        
                    BuildTree(TreeView1.Nodes, parentID)  
        
                End Sub 
        
                Private Sub LoadDataSet()  
        
                    '==ds is declared at the page level  
        
                    Dim oContacts As New ContactCollection  
        
                    ds = oContacts.GetDownline(UserInstance.ContactID, 8) '==returns a dataset...later would like to return a collection  
        
                End Sub 
        
            Private Sub BuildTree(ByVal nodes As TreeNodeCollection, ByVal IntParent As Int32)  
        
                    Dim thisID As Int32  
        
                    Dim thisName As String 
        
                    Dim children As DataRow() = ds.Tables(0).Select("SponsorID='" & IntParent & "'")  
        
                    If children.Length = 0 Then 
        
                        Return 
        
                    End If 
        
                    Dim newNode As TreeNode  
        
                    For Each child As DataRow In children  
        
                        thisID = Convert.ToInt32(child.ItemArray(0))  
        
                        thisName = Convert.ToString(child.ItemArray(2))  
        
                        newNode = New TreeNode(thisName, thisID.ToString)  
        
                        nodes.Add(newNode)  
        
                        newNode.ToggleExpandState()  
        
                        BuildTree(newNode.ChildNodes, thisID)  
        
                    Next 
        
                End Sub

Does anyone know how to do this with a RadTreeView? I almost had it working but the newNode doesn't have a ChildNodes collection.

Thanks
