Preserve TabIndex value(order) after a callback

I have defined the tabindex property on each of the webcontrols of my page, so I have 2 webcontrols with autopostback="true", but after the callback the tabindex order is lost. How can I preserve the current order(tabindex) after a callback(postback) is fired?

[Solved] Setting cell width in an Excel cell via GridExcelBuilder

When using the GridExcelBuilder to add a new cell (and row) to a worksheet when exporting from the RadGrid, is there a way to specify the width of the cell as in the pseudo-code below?

    
            protected void Grid_ExcelMLExportRowCreated ( object source, Telerik.Web.UI.GridExcelBuilder.GridExportExcelMLRowCreatedArgs e )  
        
            {  
        
                if ( e.RowType == GridExportExcelMLRowType.HeaderRow )  
        
                {  
        
                    RowElement myNewRow = new RowElement();  
        
                    CellElement myNewCell = new CellElement();  
        
                    myNewCell.StyleValue = "myNewStyle";  
        
                    myNewCell.MergeAcross = e.Row.Cells.Count - 1;  
        
                    //is there something like the property below? 
        
                    myNewCell.Width = 200;  
        
                    //etc...  
        
                }  
        
            }

Combo Box with a treeview and RadAjaxmanegerProxy

I have a combobox with a treeview ( tvCategory) inside it. ON the same web page I have a asp panel and on which I have a user Control.

I am trying to use AJAXManagerProxy control. ON treeview node change I want to update panel on the web page. Following code I have used for this.

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">

<telerik:AjaxSetting AjaxControlID="tvCategory">

<telerik:AjaxUpdatedControl ControlID="tvCategory" />

<telerik:AjaxUpdatedControl ControlID="pnlDetail" LoadingPanelID="RadAjaxLoadingPanel1" />

<telerik:AjaxUpdatedControl ControlID="txtNAme" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</telerik:RadAjaxManagerProxy>

On NodeClick event I am trying to set properties of user control.

Protected Sub tvCategory_NodeClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeEventArgs)

If e.Node.Value.ToString <> vbNullString Then

Category1.CategoryID = New Guid(e.Node.Value.ToString) 'setting up User control's categoryId property

Category1.LoadCategory = True

End If

pnlDetail.Visible = True

End Sub

Page Load of the user control is called before NodeClick event and I am not able to get the data because I need to know the node selected value to set up on the user control.

How do I do this?

Thanks is advance!!!

GridColumn make visible = true

I have a radgird that will be displaying support tickets. Within the grid I am using the telerik:GridImageColumn to display either a green, yellow or red image.

I am current trying to achieve this with itemdatabound, using findcontrol. I keep getting an error “Object reference not set to an instance of an object.”. Can some let me know what I am doing wrong?

Thanks

If

TypeOf e.Item Is GridDataItem Then

Dim dataItem As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim dataBoundItem As GridDataItem = e.Item

Dim calcdate As Date

Dim tsTimeSpan As TimeSpan

Dim iNumberOfDays As Integer

calcdate = dataItem.DataItem(

"SubmitDate")

tsTimeSpan = Now.Subtract(calcdate)

iNumberOfDays = tsTimeSpan.Days

If iNumberOfDays < 2 Then

dataBoundItem.FindControl(

Show Iframe in RadDock on button click

I want the content of each page in my docks to only load when the image button is clicked. I also would like to have this content in the RadDock so I set up an Iframe and an image button in each dock with the following code. It doesn't work to make the frame visible and load the page. What would be the correct approach to this? thank you.

function showIframe() {

document.getElementById(

"frame1").src = "DrawingTreeView.aspx";

document.all.frame1.style.visibile =

"visible";

}

</script>

Issues when integrating A Usercontrol with RADScheduler in Sharepoint

Hi,

I have created a usercontrol which contains a RADScheduler.
This works fine from the ASP.Net.
I am trying to integrate the same in sharepoint and to load the page.
But I am getting lot of issues while integrating. Please find the issues below.

1) I am having a AdvancedEdit window for editing. It opens and retrieves the values properly in sharepoint.
But when make any changes in the Edit and trying to update the same, the changes that are made are not sent in Request.
I found out this while debugging. Hence whatever change i made during edit, the values are not passed.
The same works fine in ASP.Net.
2) I am having a RADTooltip which will display values when moved over the schedules available in the scheduler.
While moving over the scheduler, the values are retrieved from the backend and is set to the text property of Labels inside another usercontrol. The Tooltip is displayed, but the usercontrol is not displayed within the tooltip.

Note: I have already used a Radtooltip inside a Grid control. The functionality is more or less the same.
The tooltip works fine in RADGrid, but creating problem with RADScheduler.

Kindly suggest solutions to the above queries ASAP.

Thanks in Advance,
Vinoth.K

[Solved] Auto-scroll to bottom of multiline RadTextBox

I'm trying to figure out a way to continuously add lines to a multi-line RadTextBox that automatically shows the last line added instead of staying at the top of the textbox. My goal is to basically display a log of events, so if there's another way I'm open to ideas. A multi-line textbox was just the first idea that came to my mind.

I've tried setting SelectionOnFocus to CaretToEnd and continuously setting the focus to the textbox, but all it seems to do is keep the caret placed on bottom of the textbox without scrolling down. Any help would be appreciated!

Thanks,
Chad
