I have a grid that has a hidden column (the Id) 

 

<telerik:GridBoundColumn DataField="Id" Display="False" Visible="false" 

           FilterControlAltText="Filter column column" UniqueName="column" >

       </telerik:GridBoundColumn>

This works fine for the grid, however when I edit or add a new record (in a popup) the Id shows up.  I can set ReadOnly="true"  which works fine for inserting a new record, this however does not work for editing an existing record.  When ReadOnly is set to true I am unable to get the Id of the record for an update. 

What am I missing here?

Thanks

Hi,

I am using RadEditor inside RadDock. In my application (Sharepoint webparts) the radDocks are dynamically created using an hidden updatepanel. In each raddock I have an UpdatePanel in order to update dynamically its content.

The first time I open a raddock with an editor inside, the editor is not editable in chrome, internet explorer and firefox. The tools are not rendered  in internet explorer. If I refresh the page with full postback, the editor starts to work correctly in all browsers.

I tried to place an hidden radeditor  (style="display: none") in my page in order to load javascript files the first time page is rendered but it does not solved my problem.

Any ideas?

We have implemented telerik TABs Load On Demand method.  We have added RadTabStrip in main usercontrol ( TopTab.ascx ).  For each pageview of tab strip, we have added separate usercontrols and set RadAjaxManager property EnabledAjax="true"

 

We are facing problem as javascript functions and validations written on usercontrols of child tabs are not getting rendered.

Below is our page structure

 

Master Page >  Client.aspx > TopTab.ascx ( user control ) > RadTabStrip ( RadTabStrip contains multiple tabs)

 

Out Of these multiple tabs we have sub tabs in 2 Tabs. For each of these sub tabs including main tabs, we have usercontrols.

 

Please suggest for rendering javascripts which are part of child / sub tabs used in our scenario.

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)

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.

Mike
