Hi Telerik,

When i add a control on my page I am getting sys.argumentundefinedexception value cannot be undefined. I have not written any code just added a control on my page and its showing above javascript exception. I am using 2010.3.1317.35 telerik.Web.UI dll.

Hi,

 I am opening a Radwindow (say mainwindow) which has usercontrol in it. The user control contains some buttons and a radgrid. I am trying to open one more child radwindow by clicking on one of the buttons 2nd radwindow opens.

The issue is when if place radgrid  in usercontrol then 2nd radwindow does not open, but if I remove radgrid then 2nd radwindow opens.

Can anyone tell me what might be the issue.

from MainPage---> opens Radwindow(usercontrol with button & radgrid)------->button click opens-------->radwindow (if radgrid on usercontrol doesnot exists)

Regards,
Shobha

Hi,
I am creating  a  dynamic nested  grid  to replicate grid displayed in following site.
 http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx

When I expand  an item in child grid to display grandChild grid, the nestedview template on top level  is empty and  I lose all controls. How can I persist nested grids  on post back.


Here is my code to create root grid, child grid is also created with same logic.

1.
  protected void Page_Init(object source, System.EventArgs e)
        {
            try
            {      
                RadGrid rootGrid = CreateDynamicGrid("Ticket");
                NGridPlaceHolder.Controls.Add(rootGrid);
            }
            catch(Exception ex)
            {
                WIMProject.ShowMessageBox(ex.ToString());
            }
        }


2.
 public RadGrid CreateDynamicGrid(string tableName)
        {
            RadGrid radGrid = new RadGrid();
            try
            {
                radGrid.ID = tableName + "_RootGrid";
                radGrid.AutoGenerateColumns = true;
                radGrid.PageSize = 20;
                radGrid.MasterTableView.AllowPaging = true;
                radGrid.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric;
                radGrid.MasterTableView.DataKeyNames = new string[] {"ID" };
                radGrid.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerOnDemand;
                radGrid.MasterTableView.TableLayout = GridTableLayout.Auto;
                radGrid.MasterTableView.NestedViewTemplate = new NestedGridTemplate();
                radGrid.ItemCommand += new GridCommandEventHandler(radGrid_ItemCommand);
                radGrid.ItemDataBound += new GridItemEventHandler(radGrid_ItemDataBound);

              radGrid.NeedDataSource += new GridNeedDataSourceEventHandler(radGrid_NeedDataSource);

        .........}


3.
        void radGrid_ItemDataBound(object sender, GridItemEventArgs e)
        {
                  string gridID = e.Item.OwnerID;
                  string tableName = gridID.Replace("_RootGrid", "");

                  if (e.Item.GetType() == typeof(GridDataItem) && e.Item.Expanded)
                      {
                          GridDataItem currentDataItem = (e.Item as GridDataItem);
                          string selectedRowID = currentDataItem.GetDataKeyValue("ID").ToString();

                          Panel currentPanel = new Panel();
                          currentPanel.CssClass = "GridWrapperPanel";

                          NestedGridTemplate nestedGridTemplate = new NestedGridTemplate();
                          nestedGridTemplate.CreateTabStrip(tableName, currentPanel, selectedRowID);

                         (currentDataItem as GridDataItem).ChildItem.NestedViewCell.Controls.Add(currentPanel);
                      }
           
        }

I am experiencing an issue with RadCompression. It does improve my intranet web application performance however I just found an issue, a web page will lose its viewstate if we leave it for around 10 minutes. It has never happened before we use RadCompression since we never let our session timeout. Does anyone know how to solve this problem?

Hi, 
I am getting the error 'ChartSeriesType' is ambiguous in the namespace 'Telerik.Charting'. I have Telerik.Web.UI dll in my bin folder. 
Here is the code

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<%@ Register TagPrefix="telerik" Namespace="Telerik.Charting" Assembly="Telerik.Web.UI" %>

<asp:Content ID="Content1" ContentPlaceHolderID="phCon1" Runat="Server">
<table><tr><td><asp:Label ID="lblMessage" Visible="false" runat="server" /></td></tr></table>
    <table>
        <tr>
        <td>From :
        <telerik:RadDatePicker ID="DateTextCalendar1" runat="server"></telerik:RadDatePicker></td>
        <td>To :<telerik:RadDatePicker ID="DateTextCalendar2" runat="server"></telerik:RadDatePicker>
</td>
        <td><asp:Button runat="server" ID="btnSubmit" Text="Apply" /></td>
    </tr>
    </table>
  <asp:PlaceHolder ID="phTestDash" Visible="true" runat="server">
        
      <telerik:RadChart ID="RadChart1" DataSourceID="SqlDataSource1" runat="server" Skin="Vista"
                        Width="465px" Height="260px" DefaultType="Line" 
                        AutoLayout="true" AutoTextWrap="true" CreateImageMap="false"  >
                        <ChartTitle>
                            <TextBlock Text="Test">
                            </TextBlock>
                          </ChartTitle>
                        <Series>
                            <telerik:ChartSeries Name="Actions" Type="Line" DataYColumn="iActions">
                                <Appearance LegendDisplayMode="ItemLabels">
                                </Appearance>
                            </telerik:ChartSeries>
                        </Series>
                        </telerik:RadChart>
  </asp:PlaceHolder>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:Test %>" ProviderName="System.Data.SqlClient" 
        SelectCommandType="StoredProcedure" SelectCommand="Test_GET">
        <SelectParameters>
            <asp:Parameter Name="TestID" DbType="Guid" />
            <asp:Parameter Name="iTestStartDateID" Type="Int32" />
            <asp:Parameter Name="iTestEndDateID" Type="Int32" />
        </SelectParameters>
    </asp:SqlDataSource>
</asp:content>

And the code behind is

Imports Telerik.Web.UI
Protected Sub LoadGraph()
             Try
                    dt = function(test)

                If dt Is Nothing Or dt.Rows.Count <= 0 Then
                    ShowMessage("No Data Available", False)
                    phTestDash.Visible = False
                    Exit Sub
                End If

            Catch ex As Exception
                ShowMessage(ex.Message, True)
            End Try
        End Sub


I went thru the forum and removed the reference from the corresponding dll. We are your customer and we need a solution for it to go forward.

Hi

I am trying to prevent empty rows with “No Child records to display” from showing the expand/colapse image. Using the code from here: http://www.telerik.com/help/aspnet-ajax/grid-hide-expand-collapse-images-when-no-records.html removed ALL of the images, even rows that did have child records to display. Could you please look at my code and see if I am missing something.

Files are attached.



Thank you.

Hi

I am using Telerik Web UI version 2010.2.1029.35. The grid has Title column as GridHyperLinkColumn with width set to 35% and no wrap.
When the Title text is too long it displays text with ... at the end of the column in IE8 which is correct. But in IE9, it does not show complete text until 35%, and after 25 chars it displays continuation text as ... even though the column width is still available. I have attached the screen snap.   

I have also tried using DataTextFormatString="<nobr>{0}</nobr>", but it didnt help. Can you pls suggest how to get the text until the end of the column? Thanks.

Hi is it possible to have the Initiator a particular Tab in a Tab Strip and its respective PageView as target Updated Control?
In the Configurator, I only see an index type name like i0, i1, i2 under my TabStrip Control... So I tried to select it as I though ti twould but got the following error

I've tried different combination without success:
1. Actual Index of the Tab  as initiator and pvSearch, pvRegister , pv Result as Updated Controls
2. tsCRMPPSA as Initiator and pvSearch, pvRegister , pv Result as Updated Controls

The only combination that works is I used the top level
tsCRMPPSA to update mpCRMPPSA .... so the whole multiplage is transferred as opposed to controls of the individual tab selcted.


Also there is a bug in the COnfigurator... When you select the indexed ta b i0, i2, i3... closed it and you try to open the configurator again to do another change, the Ajax Settings are duplicated...

Hello,
I'd like to return to the question that was sent to you 3 years ago:
http://www.telerik.com/community/forums/aspnet/chart/show-y-axis-in-reverse-order.aspx
Is there any advance in this direction? It seems to be that the answer is no. Why is it such problem to add this feature to your really good product? I used this feature in TeeChart of Steema many years ago. I attach an example to this letter.
