popup panel

I have radgrid1 for the inline editing and I have Edit, Add New Record, Delete links but also I added extra gridboundbutton called " search" and I wan to put a pop up panel for that in ItemCommand.. but my panel is not showing up.. I have searched that it says if I would have want to do my edit pop up panel I could have add EditMode = popup on the aspx page but I am not sure how to do that for the Search link, because I dont want to add pop up to Edit, Add new record , Delete functionalities.. just for Search .

<radG:GridButtonColumn ButtonType="LinkButton"
CommandName="Search" UniqueName="Search" >
<HeaderStyle />
<ItemStyle HorizontalAlign="Center" />
</radG:GridButtonColumn>

Linq - Entity Framework as datasource

Hi,

Can you please point me to an example that uses linq data as a source for the grid in the scenario something like below:

protected void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

RadGrid1.DataSource =

this.GridSource2;

}

private object GridSource2

{

get

{

Object obj = this.ViewState["_gds"];

if (obj != null)

{

return obj;

}

else

{

string s;

object ss = from i in EntityConnection.INVENTORY select new { i.INV_DEVICENAME, i.INV_DEVICETYPE };

this.ViewState["_gds"] = ss;

return ss;

}

Simple Sorting not working properly

I have a simple grid where I allow sorting. the datasource is filled with the needdatasource event. This funtion puts an IEnumerable<Canidate> into the datasource.
When I click the header of a column for the first time, everything works wel. When I click the header of the column next to the previous column, the column to right of the column I clicked is then sorted. also the sortmode is not changing when click multiple times on the same header. I have also tested this with auto generate columns, but this produces the same error.

Does anyone has an idea what is going on?

here is my code behind:

    
              protected void CandidateListGrid_NeedDataSource(object source, GridNeedDataSourceEventArgs e) 
        
                    { 
        
                        RadComboBox lastNameInput = (RadComboBox)FilterData.FindControl("LastNameInput"); 
        
                        RadComboBox firstNameInput = (RadComboBox)FilterData.FindControl("FirstNameInput"); 
        
                        RadDatePicker dateLastContractFromInput = (RadDatePicker)FilterData.FindControl("DateLastContractFromInput"); 
        
                        RadDatePicker dateLastContractUntilInput = (RadDatePicker)FilterData.FindControl("DateLastContractUntilInput"); 
        
                        RadComboBox StatusComboBox = (RadComboBox)FilterData.FindControl("StatusComboBox"); 
        
                        var statusItems = from itm in StatusComboBox.Items 
        
                                          where ((CheckBox)itm.FindControl("CheckBox")).Checked 
        
                                          select itm.Value; 
        
                        CandidateListGrid.DataSource = this.presenter.ListCandidates( 
        
                            ((lastNameInput != null) ? lastNameInput.Text : "") 
        
                            , ((firstNameInput != null) ? firstNameInput.Text : "") 
        
                            , statusItems 
        
                            , ((dateLastContractFromInput != null) ? dateLastContractFromInput.SelectedDate : DateTime.MinValue) 
        
                            , ((dateLastContractUntilInput != null) ? dateLastContractUntilInput.SelectedDate : DateTime.MinValue) 
        
                            ); 
        
                    }

here is my ascx

                    public string FirstName { get; set; } 
        
                    public string LastName { get; set; } 
        
                    public DateTime LastContractDate { get; set; } 
        
                    public string ContractState { get; set; }

To get it follow repro steps below.

Using Telerik.Web.UI.dll 2010.1.429.20 version.
Repro steps:
1) Create a Web Form
2) Use this code as the form source:

    
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

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

                <form id="form1" runat="server"> 
        
                <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> 
        
                <div> 
        
                <telerik:RadAjaxManager runat="server" ID="ajaxManager"> 
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="radWindow"> 
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="radWindow" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager> 
        
                <telerik:RadWindow runat="server" ID="radWindow" VisibleOnPageLoad="true"> 
        
                    <ContentTemplate> 
        
                        <telerik:RadDatePicker AutoPostBack="true" runat="server" ID="radDatePicker"></telerik:RadDatePicker> 
        
                    </ContentTemplate> 
        
                </telerik:RadWindow> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

3) Open the form in a browser
4) Pick up a date
5)Observe javascript exception "Sys.InvalidOperationException: Two components with the same id 'radWindow_C_radDatePicker' can't be added to the application."
Please provide a workaround as soon as possible.
