Insert and AddAt methods unexpected behavior

What is the expected behavior of the RadGrid.MasterTableView.Columns.Insert and RadGrid.MasterTableView.Columns.AddAt methods?

It seems to be replacing the column at the index position I specify, instead of inserting the column and shifting everything else in the collection across.

GridColumn employeeRateCol = RadGridSummary.MasterTableView.Columns.FindByUniqueName("EmployeeRate");

GridDropDownColumn rateType = new GridDropDownColumn();

int index = RadGridSummary.MasterTableView.Columns.IndexOf(employeeRateCol);

RadGridSummary.MasterTableView.Columns.Insert(index, rateType);

If i use the Add method, everything works as expected, but I don't want this dynmaically created column to appear as the last column

I am using the .NET 4 version of the Q1 2010 release

selected value always show empty

I
am simply trying to read the selected value of an item that is selected
in RadComboBox but I am unable to do so.  The SelectedValue value is
always empty.  This is a pretty simple usage case so I don't understand
why this should be difficult.  Does anyone know what is going on?



Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Dim cmd As New SqlCommand

Dim con As New SqlConnection

Dim da As New SqlDataAdapter

Dim ds As New DataSet

If (Not Page.IsPostBack) Then

cmd.Connection = con

con.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString

con.Open()

cmd.CommandText
= "select top 100 CustomerID, isnull(Title, '') as Title, FirstName,
LastName, FirstName + LastName as FullName from saleslt.customer"

da.SelectCommand = cmd

da.Fill(ds)

RadComboBox1.DataValueField = "CustomerID"

RadComboBox1.DataTextField = "FullName"

RadComboBox1.DataSource = ds

RadComboBox1.DataBind()

end if

End Sub

Protected
Sub RadComboBox1_SelectedIndexChanged(ByVal o As Object, ByVal e As
Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles
RadComboBox1.SelectedIndexChanged

Dim s As String

s = e.Value

s = RadComboBox1.SelectedValue

End Sub

2010 Q2 Ajax to auto-save Excel-like grid

My website users are report that they lose data when they forget to Save and such, and so I want to auto-save the data every minute using Ajax.

I have an excel-like grid that I want to auto-save using Ajax. Would you recommend the AjaxPanel or AjaxManager? And how can I hook up the timer to call Ajax?
Thanks!

Populate Radcombo in EditForm

Hi all,

I have two tables in an SQL database. One contains Customer details and the other contains Contact names. There is a one to many relationship between Customers and Contacts. I have a Radgrid for the Customers table and I'm using a pop-up EditForm for insert/update. On the EditForm there is a RadCombo to select a contact. I only want to populate this combo with the Contact Names for the selected Customer.

Below is my code. Currently it' not populating the Combo Box at all. What am I doing wrong?

Many thanks in advance,

Neil

select value from combox and set into other text box

Hi,

I have a RadGrid with 2 column (customer_number, and customer_name). When I click on the Add New Record, I would like to build 2 combox (google like), 1 for customer_number and 1 for customer_name, both has 2 columns customer_number and customer_name and when we select a value from either box, I would like to update the other box with its corresponding value. These comboxes are pulling data from MS Access while this RadGrid is from SQL.

Thanks

RadGrid inside a RadMultiPage flickers conitnuously

I am using RadGrid inside a RadMultiPage with 2 pages inside.
On each RadPageView I have a RadGrid inside. on RadPageView1, radGrid1 is rendering properly and this PageView is default.
When I click on RadTabpStrip for Second RadPageView , the RadGrid is rendering properly but continuously flickering / resizing.
but it is not posting back and no loading panel is displayed.

The same page is hosted on different machine is working fine.

The difference in between two machines is nothing. same IIS, same ASP.net runtime binding, same IIS settings ...
I see the view Source of pages that rendered in IE from both machines these are differences

from page that didnot flicker

... WebResource.axd?d=5HPxgnGtzes8WoxQ6S8BNQ2&t=634116954612965247 ...
... /ScriptResource.axd?d=Eyv-e9dZioIZivVSIFJbHHN7w0LqO85Y0LWEb-3RXt1DZu3iD0XkEMg8bjNKxxzP0feZZOXbG-KeiZh21zwtkxfBNaXSHhicEw_KYWmiH_o1&t=58e0df9d ...
...
like these ScriptResource.axd?d kind of differences only

from page that flicker

... /WebResource.axd?d=5HPxgnGtzes8WoxQ6S8BNQ2&t=634117900279042350 ...
... /ScriptResource.axd?d=Eyv-e9dZioIZivVSIFJbHHN7w0LqO85Y0LWEb-3RXt1DZu3iD0XkEMg8bjNKxxzPqWsK5IDTFG5EkTIMjnOtF7vgb17u6LAELlCfTgRVNLQ1&t=ffffffffe5251f5f" ...

In both machines I have Telerik.Web.UI.dll, version 2009.02.0826.20 is in GAC. no other Telerik.Web.UI.dll is not in GAC.

any help ???

GridDateTimeColumn with DateTimePicker popup not displaying

hi

i have a grid in a nested view template with a GridDateTimeColumn in it , but on insert/edit mode the datepicker does not show , it simply seems to go to the top of the screen when the picker button is clicked ,
the column is created as follows :-

    
                    private GridDateTimeColumn CreateDateGridColumn(XmlAttribute xAtt, XmlNode xControl, RadAjaxPanel PlaceHolder1)  
        
                    {  
        
                        System.Web.UI.Control Test = Builder.FindControl(PlaceHolder1.Controls, xAtt.Name + "Editor");  
        
                        if (Test.ID == null)  
        
                        {  
        
                            GridDateTimeColumnEditor DTE = new GridDateTimeColumnEditor();  
        
                            DTE.ID = xAtt.Name + "Editor";  
        
                            PlaceHolder1.Controls.Add(DTE);  
        
                        }  
        
                        GridDateTimeColumn DT = new GridDateTimeColumn();  
        
                        DT.UniqueName = xAtt.Name;  
        
                        DT.HeaderText = xControl.Attributes["Caption"].Value;  
        
                        DT.PickerType = GridDateTimeColumnPickerType.DatePicker;  
        
                        DT.DataFormatString = "{0:MM/dd/yyyy}";  
        
                        DT.ColumnEditorID = xAtt.Name + "Editor";  
        
                        DT.DataField = xAtt.Name;  
        
                        DT.SortExpression = xAtt.Name;  
        
                        DT.ItemStyle.Width = Unit.Pixel(120);  
        
                        DT.FilterControlWidth = Unit.Pixel(50);  
        
                        DT.DataType = System.DateTime;  
        
                        DT.EmptyDataText = " ";  
        
                        return DT;  
        
                    }

the grid is created in the Page_init function, i am also using the latest version of the telerik controls.

can anyone suggest a reason why the picker would not be popping up ?

Peter.
