Questions on UI for ASP.NET AJAX Forum

Hello techies,

We are using the RagGrid on a test page for performance testing.
We were surprised to notice that a simple page with 100 elements in the GRID takes on an average about 2 seconds. We are doing a load test on Win Server 2008 R2. We are not using a real database. We are using a STUB to generate the 100 odd elements.
The same STUB when used on ASP.net MVC page with simple HTML table rendering out performs the RadGrid Page. The MVC page takes about 0.37 seconds.

Test Environment : ASP.net 4.0 / RadControls for ASP.NET AJAX Q2 2011 SP1 / Windows Server 2008 R2 / IIS 7.5 / Application pool type “Integrated Pipeline”

Any ideas?

Advance thanks,
Clement

MarkFirstMatch is auto completing sentences in combobox

I have a Rad combo box that when you type it starts completing sentences instead of just marking the one that is most similar.

<telerik:RadComboBox ID="rcbSiteSearch" runat="server" Width="190px" Height="100px" EnableLoadOnDemand="True" ShowMoreResultsBox="true" MarkFirstMatch="true" AllowCustomText="true" EnableVirtualScrolling="true" OnItemsRequested="rcbSiteSearch_ItemsRequested" />

Protected Sub rcbSiteSearch_ItemsRequested(ByVal sender As Object, ByVal e As RadComboBoxItemsRequestedEventArgs)

Const ItemsPerRequest As Integer = 5

Dim data As DataTable = GetSiteName(e.Text)

Dim itemOffset As Integer = e.NumberOfItems

Dim endOffset As Integer = Math.Min(itemOffset + ItemsPerRequest, data.Rows.Count)

e.EndOfItems = endOffset = data.Rows.Count

For i As Integer = itemOffset To endOffset - 1

rcbSiteSearch.Items.Add(New RadComboBoxItem(data.Rows(i)("name").ToString(), data.Rows(i)("value").ToString()))

Next

e.Message = GetStatusMessage(endOffset, data.Rows.Count)

End Sub

Private Shared Function GetSiteName(ByVal text As String) As DataTable

Dim StateCode As String = "pa"

Dim connectionString As String = *Connection String*

Dim QueryStr As String = *QUERY*

Dim adapter As New SqlDataAdapter(QueryStr,connectionString)

Dim Data As New DataTable()

Try

adapter.Fill(Data)

Catch ex As Exception

Call MsgBox(String.Format("Unexpected Error: {0}", ex.ToString()), 0, "Unexpected Search Error")

End Try

Return Data

End Function

Private Shared Function GetStatusMessage(ByVal offset As Integer, ByVal total As Integer) As String

If total <= 0 Then

Return "No matches"

End If

Return [String].Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>", offset, total)

End Function

Grid forcing column width downward

I am using a grid control and when I enable the show group panel and enable that functionality, my columns are shrunk down to fit in the window. There is no overflow shown at all. This issue can be resolved by putting the browser (IE) in to IE8 compatibility Mode with and IE 8 Document Mode. The issue with this is when I make this change, the columns in my grid no longer line up with the header. This issue goes away completely if I remove static headers and scrolling but I need both of those things. This is the grid creation code from the code behind in C#:

protected virtual void SetupGridProperties(int pageSize)

{

_gridObj.Width = Unit.Percentage(97);

_gridObj.Height = Unit.Percentage(95);

_gridObj.ID = "gridRpt";

_gridObj.Skin = ConfigurationManager.AppSettings.Get("WebGridStyle");

_gridObj.AllowPaging = true;

_gridObj.PageSize = pageSize;

_gridObj.PagerStyle.Mode = GridPagerMode.NextPrevNumericAndAdvanced;

_gridObj.PagerStyle.Position = GridPagerPosition.Top;

_gridObj.PagerStyle.AlwaysVisible = false;

_gridObj.AllowSorting = true;

_gridObj.GridLines = GridLines.Both;

_gridObj.AllowMultiRowSelection = false;

_gridObj.ClientSettings.AllowColumnsReorder = true;

_gridObj.ClientSettings.ColumnsReorderMethod = GridClientSettings.GridColumnsReorderMethod.Reorder;

_gridObj.ClientSettings.Selecting.AllowRowSelect = true;

_gridObj.ClientSettings.Selecting.CellSelectionMode = GridCellSelectionMode.SingleCell;

_gridObj.ClientSettings.Selecting.CellSelectionMode = GridCellSelectionMode.MultiCell;

// _gridObj.ClientSettings.Selecting.AllowCellSelect = true;

// _gridObj.ClientSettings.Selecting.AllowMultiCellSelect = true;

_gridObj.ClientSettings.ClientEvents.OnGridCreated = "gridRpt_GridCreated";

//_gridObj.ClientSettings.ClientEvents.OnRowMouseOver = "_gridObj_RowMouseOver";

_gridObj.ClientSettings.ClientEvents.OnRowSelecting = "gridRpt_OnRowSelecting";

_gridObj.ClientSettings.ClientEvents.OnRowDeselecting = "gridRpt_OnRowDeSelecting";

_gridObj.ClientSettings.ClientEvents.OnRowClick = "gridRpt_OnRowClick";

//_gridObj.ClientSettings.Resizing.AllowRowResize = true;

_gridObj.ClientSettings.Scrolling.AllowScroll = true;

_gridObj.ClientSettings.Scrolling.UseStaticHeaders = true;

_gridObj.GroupPanel.Visible = false;

_gridObj.ClientSettings.AllowDragToGroup = true;

_gridObj.GroupingEnabled = true;

_gridObj.ShowGroupPanel = true;

_gridObj.GroupPanel.Enabled = true;

_gridObj.MasterTableView.TableLayout = GridTableLayout.Auto;

_gridObj.ItemStyle.VerticalAlign = VerticalAlign.Middle;

//this._gridObj.ExportSettings.IgnorePaging = true;

//this._gridObj.ExportSettings.OpenInNewWindow = true;

//this._gridObj.ExportSettings.IgnorePaging = true;

_gridObj.MasterTableView.SortExpressions.AllowNaturalSort = false;

_gridObj.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerBind;

_gridObj.AutoGenerateColumns = false;

_gridObj.MasterTableView.AutoGenerateColumns = false;

}

This is a link to what I am seeing: BROKEN GRID . This only happens when I drag a column to group by.

$find(AjaxManager) returns null after second request

I have a very simple test page that contains the following:
RadAjaxManager
RadScriptManager
RadUpload
RadWindowManager
input type="button" x 2

The input buttons fire client-side events that cause an ajaxRequest.
This only works with the first ajaxRequest. Thereafter the $find("<%= RadAjaxManager1.ClientID %>"); does not find the RadAjaxManager

    
            <head runat="server"> 
        
                <title></title>

I have tried the setTimeout("InitiateAjaxRequest(FileString);", 0); trick but it does not make a difference.

MenuItem onclick not firing

I have a page where the user can change an address, and when they click Update, I need to run some javascript on the page to ask if they want to change some related addresses, THEN run the code on the server.

So on the .aspx page I have a javascript function:

function confirmAddressChange()

{

if (document.forms[0].hfAddressChange.value =="")

{

var res = (confirm('Update Contact Addresses to Match?')==true);

document.forms[0].hfAddressChange.value = res;

}

return true;

}

and on the RadMenuItem I have: BTW, I've tried onClick, onItemClick, onclick and the one in the code now.

<rad:RadMenuItem ID="rmitmUpdateInfo" runat="server" ImageUrl="~/Images_ABL_Std/Grid/Update.gif"

Text="Update" Value="update" ToolTip="Accept changes" OnClientItemClicking ="confirmAddressChange()">

</rad:RadMenuItem>

What I need to happen is to have the page run the javascript, where I set the value of a hidden field, then run the server code. At this point it skips the javascript and goes directly to the server code.

Anyone have a suggestion or answer?

Thanks.

Issue in using an external javascript file in RadCodeBlock

Hi All,

I have a problem regarding javascript. When I am using external javascript(for validation purpose) in aspx page, its working fine. But when i am using external javascript to validate telerik controls, it is showing some errors. So kindly guide me how I can solve my issue.

// This following code works fine.
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
        <script language="javascript" type="text/javascript">
            function Delete_Confirm(sender, args) {
                var selRowCount = -1;
                selRowCount = $find("<%=rgDocument.ClientID %>").get_masterTableView().get_selectedItems().length;

                if (selRowCount > 0) {
                    radconfirm('Sure to delete?', deleteConfirmCallbackFn, 330, 100, null, 'Example', null);
                }
            }

            function deleteConfirmCallbackFn(args) {
                if (args) {
                    __doPostBack('toolBar', 'Delete');
                }
            }
        </script>
    </telerik:RadCodeBlock>

Now i have written the above script in "CommonJS.js" and included it in to "RadCodeBlock". But I am getting the error "function not defined.".

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
       <script type="text/javascript" src="js/CommonJS.js"></script>

        </script>
    </telerik:RadCodeBlock>

Thanks and Regards
