Hi,

It seems that when using the AdvancedForm.ascx the controls I've added, like asp:DropDownList, are automaticaly databound.

What can I do to prevent this from happening?

It's important for me to have control over the databinding because the lists depend on each other.
In the current situation the controls are bound twice, Causing the value to be lost

Regards,
Ron

Thanks for your help

RadWindow example DialogReturnValue

I have been working with the RadWindow example DialogReturnValue.

What I would like to do is a similar application but rather than using a textarea, I would like to use a Wizard from the "Standard" toolbox.

However, any time I add a wizard (or any other control including standard textbox and even HTML Input (Text), I get an error in the GetRadWindow function of the Dialog.aspx page

- Microsoft JScript runtime error: Object required

This happens on the line

else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;

Any suggestions greatly appreciated

How to Display Grid inside RadTooltip?

Hi,

I have a grid that I want to add tooltip capabilities to. I tried using the
Tooltipmanager. For some reason when I dynamically add the grid rows or grid controls as target controls to the Manager, the flyout tooltip never gets fired. So using the Tooltip manager with a ascx user control would not be option at this time.

After spending considerable time on it and looking at different online examples, we decided to use just the regular RadTooltip. This works on the grid and I am able to display dynamic content in the tooltip.

The question I have is that, would it possible to display a grid inside of a Radtooltip(not using the tooltipmanager ascx user control method).

If I am able to use a RadGrid or a regular ASP.net Grid inside of the <RadTooltip> tags, how would I go about binding this grid to a datasource like a datatable in the markup or through code behind.
Following is the markup for my grid that the tooltip functionality is applied to. The tooltip section is marked in red:

<

telerik:RadGrid runat="server" AllowPaging="True" ID="RadGridReports" Height="320px" PagerStyle-Mode="Slider"

Width="375px" GridLines="None" AutoGenerateColumns="false" ClientSettings-ClientEvents-OnRowDropping="onGridReportsRowDropping"

ClientSettings-EnablePostBackOnRowClick="true" ClientSettings-ClientEvents-OnRowDragStarted="onGridReportsNodeDragging">

<telerik:GridBoundColumn DataField="TemplateID" HeaderText="TemplateID"

SortExpression="TemplateID" Visible="false" UniqueName="TemplateID" />

<telerik:GridBoundColumn DataField="TemplateName" HeaderText="Saved Templates"

SortExpression="TemplateName" Visible="true" UniqueName="TemplateName" />

<telerik:GridTemplateColumn HeaderText="View Details" SortExpression="ViewDetails" UniqueName="ViewDetails">

<asp:Label ID="lbl" runat="server" Text="Hover to show a tooltip"></asp:Label>

<telerik:RadToolTip ID="RadToolTip1" runat="server" TargetControlID="lbl" RelativeTo="Element" Skin="Default"

Position="BottomLeft">

There are

<%

#DataBinder.Eval(Container, "DataItem.TemplateID")%>

customers from

<%

#DataBinder.Eval(Container, "DataItem.TemplateName")%>

</telerik:RadToolTip>

</ItemTemplate>

</telerik:GridTemplateColumn>

</columns>

</RowIndicatorColumn>

</ExpandCollapseColumn>

</EditFormSettings>

</MasterTableView>

</ClientSettings>

</telerik:RadGrid>

any help would be appreciated

Rendering problem of Custom Radcombox Asp.net

Hi,

I have created a custom control (combo box) inheriting Telerik ComboBox. I have added some property in addition to the property provided by the Telerik.

In the design time after dragging and dropping the combobox, I tried adding an item for the combobox which resulted in the following error

Combobox - Combobox1There was an error rendering the control.

Type 'ComboboxControl.Combobox' does not have a public property named 'RadComboBoxItem'.

Source view of my control is as follows:

<cc4:Combobox ID="Combobox1" runat="server" Text="DropDownList">

<telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1"></telerik:RadComboBoxItem>

</cc4:Combobox>

[Solved] Adding tabs and pageviews in codebehind

I'm stumbling once again. This time, I'm trying to dynamically add tabs and an associated pageview to when an item from a RadGrid is selected.

The tab is created and selected, however the text does not get set, nor does it appear that the pageview is created. I've verified with a radalert that the e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["queueid"].ToString() does return a valid string.

What am I missing here?

    
            protected void QueueGrid_ItemCommand(object source, GridCommandEventArgs e) 
        
            { 
        
                if (e.CommandName == "RowClick" && e.Item is GridDataItem) 
        
                { 
        
                    if (RadTabStrip1.FindTabByText(e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["queueid"].ToString()) == null) 
        
                    { 
        
                        RadTab tab1 = new RadTab(); 
        
                        RadTabStrip1.Tabs.Add(tab1); 
        
                        RadPageView newpage = new RadPageView(); 
        
                        RadMultiPage1.PageViews.Add(newpage); 
        
                        newpage.ID = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["queueid"].ToString(); 
        
                        tab1.Text = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["queueid"].ToString(); 
        
                        tab1.Value = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["queueid"].ToString(); 
        
                        tab1.PageViewID = newpage.ID; 
        
                        RadTabStrip1.SelectedIndex = RadTabStrip1.SelectedIndex + 1; 
        
                        RadMultiPage1.SelectedIndex = RadMultiPage1.SelectedIndex + 1; 
        
                    } 
        
                } 
        
            }

DNN RadGrid Demo Module

Hi Telerik,

I have looked at your demo of RadGrid in a DNN module and was wondering if you could make the module source available? This would be a good example to be used to show how to integrate your grid in place of the standard microsoft grid that DNN uses by default. If you have a VS 2008 project file that goes with this module in WAP format that would be best!

Thanks Todd.

Cannot get the Selected Node from the ClientSide

I am trying to find the selected node in a TreeView on the client side.

I have tried the code in this example which is linked to in a similar thread listed here.

I am not able to figure out what I am doing wrong. When calling GetSelectedNodes() I contiune to get the error message "Object does not support this property or method". I have tried setting MultiSelect = true and false with the same error.

Here is a sample of my code.

    
            <body> 
        
                <script type="text/javascript">  
        
                    function getSelectedNodes()  
        
                    {  
        
                        var tree = <%= RadTreeView1.ClientID %>;  
        
                        var nodes = tree.GetSelectedNodes();  
        
                        alert(nodes.length);  
        
                    }  
        
                </script> 
        
                <form id="form1" runat="server">  
        
                <asp:ScriptManager ID="ScriptManager1" runat="server">  
        
                </asp:ScriptManager> 
        
                <telerik:RadTreeView ID="RadTreeView1" runat="server">  
        
                    <Nodes> 
        
                        <telerik:RadTreeNode runat="server" Expanded="True" Text="1" Value="1" /> 
        
                    </Nodes> 
        
                </telerik:RadTreeView> 
        
                <input id="Button1" type="button" value="Get Selected Node" onclick="getSelectedNodes();" /> 
        
                </form> 
        
            </body>
