Hello Team,

I am facing an issue in the Rad Pane.

In my application i have two Rad Pane - Left Pane and the middle pane. Whn i load the page the left pane is collasped and middle pane is displaying. I am keeping some static controls in my left pane. When i click on the left pane title on the left side of the Rad Splitter left Pan with the controls will display. When i done any events on the left pane without clicking on the pane i want to get the focus back to the middle pane.

Right now middle pane is loading and after few second the control will go to the left pane. How i can able to get the focus on the middle pane after done any operations in the left pane.

Thanks & Regards,
Sushanth Mathew

[Solved] Cannot load from xml

I have tried mulitple ways to load the treeview and I cannot find one way that works.

For instance I have tried using this:

    
            RadTreeView1.LoadXml(GetTransformedXmlDoc("TreeViewCombined2.xsl", args));

Where GetTransformedXmlDoc() returns a correct xml document as a string. All it does is give me XML errors and shows me a node that doesn't even exist in the xml string. This is what it tells me: "There is an error in XML document (1, 40)." When I check for the specific error message this is what I get: "<Nodes xmlns=''> was not expected."

Where that node comes from I have no idea. It's not in the xml I am looking at.

I have tried:

    
            RadTreeView1.DataSource = GetTransformedXmlDoc("TreeViewCombined2.xsl", args);  
        
            RadTreeView1.DataBind();

Where GetTransformedXmlDoc() returns an XmlDataSource object. This sort of worked except I couldn't keep the root node from appearing in the treeview and it also screwed up the text properties of the nodes. Below is a sample xml doc in the exact same form as the one I am trying to load. I cannot set the DataTextField="Text" or the TextField="Text" because my root node doesn't contain that attribute. Is there a way around this?

    
            <Nodes> 
        
              <TreeViewNode ID="1" Text="Node 1" /> 
        
              <TreeViewNode ID="2" Text="Node 2" /> 
        
              <TreeViewNode ID="3" Text="Node 3" /> 
        
              <TreeViewNode ID="4" Text="Node 4">  
        
                <TreeViewNode ID="5" Text="Node 5" /> 
        
              </TreeViewNode> 
        
              <TreeViewNode ID="6" Text="Node 6" /> 
        
            </Nodes>

I would appreciate any help as I have wasted the better part of 2 days trying to get this thing to load correctly.

EditMode="PopUp" with TextBox MultiLine when press Enter

DateInput border with InvalidStyle and RequiredFieldValidator

    
            Datum 2&nbsp;<asp:RequiredFieldValidator ID="rfv2" ControlToValidate="RadDatePicker2" runat="server" 
        
                             ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>   <br />

                            </DateInput> 
        
                        </telerik:RadDatePicker>

Hi,
I need RadDatePicker with RequiredFieldValidator. Submitting with no Date shows the errorMessage from RequiredFieldValidator. But I expected to get a red border for DateInput too (InvalidStyle ...). But nothing happens. Whats running wrong?

PanelBar adding dynamically created controls

Hello !

i've got a question about Telerik RadPanelBar control.

For example we've got a RadPanelBar control on form :

        <telerik:RadPanelBar ID="testPanelBar" runat="server">
        </telerik:RadPanelBar>

and a button which adds a new item to this RadPanelBar at runtime:

        RadPanelItem newParentItem = new RadPanelItem();
        RadPanelItem newChildItem = new RadPanelItem();
        newChildItem.Controls.Add(new RadTextBox());
        newChildItem.Text = "wazzap";
        newParentItem.Items.Add(newChildItem);
        languagesPanelBar.Items.Add(newParentItem);

when i click button, new RadPanelItem is added with all child controls(in this case it's RadTextBox in child item)

when button is clicked second time, second RadPanelItem is added with all controls, but this time RadTexBox control dissapeared from first RadPanelItem.

And same when button is clicked for third time, new item added with all controls, but RadTextBox will dissapear from 1st and 2nd items.

am i doeing something wrong when dynamically adding items ?

Thank You !

Performance - Pages loading slow due to docks

We are using raddocks reading content from database and displaying on webpages, such pages load 5X slower than a normal page.

Column width not working when grouping is enabled

I have created a RadGrid with 4 columns and grouping enabled. The last two columns have a width specified using the ItemStyle-Width property. When the grid renders the width's are not honored and end up drawing wider than the specified width. Using the IE development toolbar I found the tag that renders in the GridGroupHeaderItem and set the css attribute display:none. As soon as I do that the widths are rendered correctly.

There appears to be an issue with having a tag inside of the <td> tag of the group header row. However, I do not know how to prevent this tag from rendering.

I am using the default skin and 2009.1.402.35 version of the controls.

    
            <rad:RadGrid ID="rgBuySell" runat="server" Width="100%" AutoGenerateColumns="false" onitemdatabound="rgBuySell_ItemDataBound" onneeddatasource="rgBuySell_NeedDataSource" onitemcommand="rgBuySell_ItemCommand" onprerender="rgBuySell_PreRender">  
        
                <MasterTableView ShowGroupFooter="true" DataKeyNames="fkAssetFrom">  
        
                    <Columns>
