parentID values

Is it possible to return a parentID values that are loaded dynamically (MS SQL server)?

I’m using the code below but I’m only getting values from the items that are within the tab.

Protected Sub RadPanelbar_ItemClick(ByVal sender As Object, ByVal e As Telerik.WebControls.RadPanelbarEventArgs) Handles RadPanelBar.ItemClick

Dim ItemClicked As Telerik.WebControls.RadPanelItem = e.Item

End Select

Response.Write("Server event raised -- you clicked: " + CStr(ItemClicked.Value))

End Sub

Ajax Panels Updating other child Ajax Panels

Hi All,

I'm trying to get one ajax panel to cause another ajax panel to update its content when both ajax panels are children of a user control in two different ajax panels on that control.

It seems to work fine in the code behind and no errors are displayed. But on the page nothing updates.

Then if you interact with the ajax panel control that is meant to change and cause a postback it then shows the changes that were meant to be there.

Is it possible for two child ajax panels to interact with each other?

cheers
Adam.

RadTextBox Growing

Is there a way to set the width on a RadTextBox and not have it grow if the entered text is longer than that width?

I am using a RadTextBox in a RadGrid. I have set the width to 200px for the textbox itself. However, if the user enters a bood bit of text, the textbox will grow out to the right thus making the entire grid grow to the right - and off the edge of the screen.

Thanks,
David Martin

[Solved] Bug? Can only dynamically add one item at a time to a RadDockZone?

I took the sample code on the website and modified it to add an array of items. Basically I have an array of strings and for each stirng in that array add a new RadDock control to the RadDockZone and have the RadDock's text property = the string value in the array.
From the originial code I have only modified the code below.
This sounds simple enough but for some reason only the first item in the array is being added to the RadDockZone.
So I'm guessing it has to do something with the order of precedence?

    
            private void AddDocks(string text)  
        
                    {  
        
                        RadDock dock = CreateRadDock(text);  
        
                        //In order to optimize the execution speed we are adding the dock to a   
        
                        // hidden update panel and then register a script which will move it  
        
                        // to RadDockZone1 after the AJAX request completes. If you want to   
        
                        // dock the control in other zone, modify the script according your needs.  
        
                        UpdatePanel1.ContentTemplateContainer.Controls.Add(dock);  
        
                        ScriptManager.RegisterStartupScript(  
        
                        dock,  
        
                        this.GetType(),  
        
                        "AddDock",  
        
                        string.Format(@"function _addDock() {{ 
        
                Sys.Application.remove_load(_addDock); 
        
                $find('{1}').dock($find('{0}'));

                        // later, the DockZoneID will be empty. To workaround this problem we will   
        
                        // set the AutoPostBack property of the RadDock control to true and will   
        
                        // attach an AsyncPostBackTrigger for the DockPositionChanged client-side

Able to drag RadDock off-screen

Hi,

We have a situation where our testers have found that, if they undock a window so it's floating, they can then grab the window and fling it off-screen. As the position of the dock is saved in viewstate, the dock remains off-screen and you can't get it back.

Is there any way of preventing a user from dragging beyond the screen bounds without us have to develop custom code to do this?

Thanks,

.s

Does current futures build support LINQ datasources ?

I come accross a bug (or at least i think it is)

First I need to ask -does the latest RagGrid 2008 Q1 'futures build' support LINQ datasources -or code linq generated queries from codebehind?

If not then when binding a RadGrid to LINQ datasource -an error occurs when paging...

Executing server-side code onSelectedIndexChanged??

I've been working on this for a couple days now and I'm stumped. I have a RadGrid on my page and I've set the OnSelectedIndexChanged event to a method that I've created. But when I select a row it just refreshes the page. If I run in debug mode it doesn't execute the method I've defined. If I look at the SelectedValue it's null, the SelectedIndexes.Count = 0, the SelectedItems.Count = 0. What am I missing here? This is fairly trivial to do with GridView, so I'm shocked it's causing me such a headache in RadGrid... I'd really like to be able to just select a row, not a Select checkbox or button or link. What I want to do is redirect to a detail page, based on the SelectedValue.

One more related item - is there a way to highlight rows onmouseover? Again, this is fairly simple to implement in GridView by adding an attribute in the RowDataBound method. But I've tried the same thing in RadGrid and nothing I try works. I know there's a "EnableRowHoverStyle" option, but it was left out of the build that I have for some reason, so I need a workaround.

Thanks for the help!
Eddie

Radwindow 2008 Q1 - Missing Title Background

Hello all,
When I use the RadWindow I am having problems with the popup window showing the background of the title bar.
The spacing is correct, and the icons are usually there and function (though they look strange with the Default skin but they work).

In 2007 Q3, I could choose the Monochrome skin and the title bar was right, but the default skin also had the same problem in Q3.

I have read a refernce to using it in an update panel, but I am not using an update panel at all on the page.

The page contains a gridview, and is a content page with a master page, but nothing revolutionary there.

The window seems to popup fine and all functions work, I just cannot get the title bar background to show properly.

Thanks in advance!
Heath

Column Sorting Problem

I have a Radgrid on my page:

<

telerik:RadGrid ID="RadGrid1" OnColumnCreated="RadGrid1_ColumnCreated" runat="server" style="text-align: left" AutoGenerateColumns="False" GridLines="None">

</RowIndicatorColumn>

</ExpandCollapseColumn>

</EditFormSettings>

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

UniqueName="gcolumn1" >

</telerik:GridBoundColumn>

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

UniqueName="gcolumn2" >

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Orig Qty" HeaderText="Orig Qty"

UniqueName="gcolumn3" >

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Shiped Qty" HeaderText="Shiped Qty"

UniqueName="gcolumn4" >

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

I want to allow sorting for just my first column. but code is not working.

Protected Sub RadGrid1_ColumnCreated(ByVal sender As Object, ByVal e As GridColumnCreatedEventArgs) Handles RadGrid1.ColumnCreated

If TypeOf e.Column Is GridHyperLinkColumn Then

Dim col As GridHyperLinkColumn = DirectCast(e.Column, GridHyperLinkColumn)

If col.UniqueName = "gcolumn1" Then

col.SortExpression =

True

End If

End Sub

update/insert data for the child/details Table of the hierarchical grid.

Hi I am trying to update/insert/delete data in the a heirarchical grid from code behind.

I am checking for the dataMember currently to update/insert/delete respectively from master/detail grid.

protected

void myGrid_DeleteCommand(object source, GridCommandEventArgs e)
{

if

(e.Item.OwnerTableView.DataMember == "Orders")
{

DataRow[] deleteRow = AssignmentRailItemDS.Tables["Orders"].Select("OrderID = " + e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["OrderID"]);
deleteRow[0].Delete();

}

else if (e.Item.OwnerTableView.DataMember == "Products")
{

DataRow[] deleteChildRow = AssignmentRailItemDS.Tables["Products"].Select("ProductID = " + e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ProductID"]);
deleteChildRow[0].Delete();

}

Is this the right approach?
Can I have a working example of the insert/delete operations?
