I have implemented a custom RadMenu that contains a RadCombobox to handle the
filtering for the column. The RadComboBox is working perfectly, however, I am trying
to implement the javascript filter code used with the Filter Template and haven't had
any luck. Below code gives me a "Cannot convert type 'System.Web.UI.Page' to
'Telerik.Web.UI.GridItem'" error on the var tableView.

Javascipt code located in <Body>

function test(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

tableView.filter(columnname, args.get_item().get_value(),

"EqualTo");

}
ASPX CS Code to add RadComboBox

public

class MyTemplate : ITemplate

{

#region

ITemplate Members

public void InstantiateIn(Control container)

{

RadComboBox RCB = new RadComboBox();
RCB.ID="RCB_" + column1;

RCB.AutoPostBack =

true;

RCB.DataSourceID = RadGrid2.DataSourceID;

RCB.DataTextField = column1;

RCB.DataValueField = column1;

RCB.OnClientSelectedIndexChanged =

"test";

container.Controls.Add(RCB);

}

#endregion

}

I can't figure this one out. Any ideas?

Two issues with RadComboBox

Hello,

I'm using the combobox several times on my page.

The first issue is as follows:

I have two comboboxes inside a div. preceding each combobox is a label. All these controls fit inside a single row and. When I add one of the comboboxes to be modified during an ajax callback with an RadAjaxManagerI get another div element that is part of the combobox that changes the positioning of my elements and they no longer stay in the same line. The name of the div is suffixed with Panel.

The second issue:

In the same page as before, I have a GridView. Inside the GridView I have an EditTemplate that contains a RadComboBox control. When I click on the edit button of a certain row in the grid, the combobox is rendered with a gray image (which I think is part of the sprite skin) below it. I couldn't find a way to eliminate its appearance.

This is the template column which contains the combbox

    
            <asp:TemplateField HeaderText="aaaHeader">  
        
                                <ItemTemplate> 
        
                                    <asp:Label ID="aaaLabel" runat="server" /> 
        
                                </ItemTemplate> 
        
                                <EditItemTemplate> 
        
                                    <telerik:RadComboBox ID="aaaBox" Width="50px" runat="server" MarkFirstMatch="true" 
        
                                        AllowCustomText="false">  
        
                                    </telerik:RadComboBox> 
        
                                </EditItemTemplate> 
        
                            </asp:TemplateField>

Any Ideas?

Thanks,

[Solved] Setting the buttons when used as a RadGrid CommandItem

I've a grid in a UserControl. The CommandItem template is defined like this ...

    
                    <CommandItemTemplate> 
        
                    <telerik:RadToolBar runat="server" ID="GridCommandItemToolbar" AutoPostBack="false" Skin="WebBlue" 
        
                        OnClientButtonClicked="ToolBarButtonClicked" Style="width: 100%" Visible="true"> 
        
                        <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                        <Items> 
        
                            <telerik:RadToolBarButton runat="server" Enabled="false" ToolTip="Add Document" Value="AddDocument" ImageUrl="~/Images/Office/document_file/png/16/document_add_16x16.png"> 
        
                            </telerik:RadToolBarButton> 
        
                            <telerik:RadToolBarButton runat="server" Enabled="false" ToolTip="Edit Document" Value="EditDocument" ImageUrl="~/Images/Office/document_file/png/16/document_edit_16x16.png"> 
        
                            </telerik:RadToolBarButton> 
        
                            <telerik:RadToolBarButton runat="server" Enabled="false" ToolTip="Delete Document" Value="DeleteDocument" ImageUrl="~/Images/Office/document_file/png/16/document_delete_16x16.png"> 
        
                            </telerik:RadToolBarButton> 
        
                            <telerik:RadToolBarButton runat="server" IsSeparator="true"></telerik:RadToolBarButton> 
        
                            <telerik:RadToolBarButton runat="server" Enabled="false" ToolTip="View Document History" Value="ViewHistory" CheckOnClick="true" Checked="false" AllowSelfUnCheck="true" ImageUrl="~/Images/Office/document_file/png/16/document_properties_16x16.png"> 
        
                            </telerik:RadToolBarButton> 
        
                        </Items> 
        
                    </telerik:RadToolBar> 
        
                    </CommandItemTemplate>

I need to be able to enble/disable the buttons based on values and events on the calling page.

I thought to do it like this ...

    
            var tb = $find("<%= GridCommandItemToolbar.ClientID %>");

But "GridCommandItemToolbar" isn't recognised, which I suppose is OK. But I can't seem to create a property on the UserControl that lets me get at the ToolBar server-side so I can access its ClientID in the <% %> code block on the page.

Can anyone offer a solution?

Show/hide column not persisting across pages

This is an FYI. I created a support ticket for this issue and thought it would be helpful to post the work-around for others.

I was using the RadGrid with the header context menu enabled and using a web service as the data source. The issue I had was with hiding/showing columns.

1. Use header context menu to hide column.
2. Use menu to show hidden column.
3. Go to another page.
4. The shown column is again hidden.

Here's the fix that was provided from Telerik.

ASPX

TreeView with combobox

hi ALL,
I am trying to implement RADTreeView in the RADCombox box. Iam adding all the items in the source. In the code behind iam using RADTreeView_Node Click event to get the selected value of the tree. when i click on the Treeview I should get the selected value of the tree into combobox.

But when iam selecting the value in the TreeView, it should get displayed in the combox box.

If i write like this

RadTreeView treeView1 = (RadTreeView)RadCombobox2.Controls[2].FindControl("RadTreeCombo");

RadCombobox2.Text = treeView1.SelectedNode.Text;

I can see that text is added to the combobox , when i keep break point.

But when the page is displayed iam not able to see the value in the comobox.
Do i need to write any other events for this.

Pls help me out........

Regards,
Asra
