IHello,

I am trying to insert a preslected set of values into a table (Activity)  trough the check box list. however I am getting nothing inserted. I have got 3 tables which are.     Job,      |        Activity,                |  ActivityDetails
                                            ========================================
                                                              |        JobId                   |
                                                              |       ActivityDetailIdI     |

the preselected values are coming from the ActivityDetails table (5 values).

I am folling the example from the demo." Control Insert with ToolTip"

Thanks I have done it

Hi everyone

First of all, I'm aware of another existing thread that has the almost same title; I've read it, and it didn't solve my problem; therefore I decided to write a new thread.

My problem goes as follows:

I have an UpdatePanel placed in a page, which is defined as follows:

I need the Label and the Label's type to invoke some JavaScript with the ScriptManager.RegisterStartupScript method, which we will see later; both the UpdatePanel and Label are only needed for this purpose, and the RadComboBox is not placed in there!

The following is the JavaScript method I need to invoke using the ScriptManager.RegisterStartupScript:

And the following is the RegisterStartupScript method I use in the code-behind file:

Everytime the JavaScript method gets invoked by the RegisterStartupScript method from the code-behind, I get the following error on the client-side:

Uncaught TypeError: Cannot call method 'get_text' of null

The RadComboBox can't be found on the client-side using $find in this special situation. If I try to access it from Chrome's JS Console using the $find method, I'll get the object, and the invocation of a method on it works perfectly. 

What am I doing wrong here? How can I fix this? It's a pretty annoying little problem, and I hope somebody can point me to the right direction.

Thanks very much in advance guys!

I have a RadGrid with the property UseStaticHeaders = true for freezing the header row while scrolling.
but when i set this property to true Width of Headers does not match the corresponding Column Header Width while setting that property to false keeps headers and columns width match. How can i have frozen headers matching columns width?

After being unable to resolve this issue with my own code, I tried running the demo site in IE7. To my surprise, it has the same issue.

Steps to Recreate

1. Go to: http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/filtering/defaultcs.aspx
2. Filter by shipped date: enter a date or use the date picker, click on the associated filter icon
3. View the results...

Hi,

We have a hyperlink in the radgrid and unfortunately the filtering doesn't work.
The following ASPX code have been used:

<telerik:GridHyperLinkColumn HeaderText = "Discussion Name" DataTextField="Discussion_Name"
ItemStyle-HorizontalAlign="Left" UniqueName="Discussion_Name"
DataNavigateUrlFields="Discussion_Id" SortExpression="Discussion_Name" ItemStyle-Width="320"
DataNavigateUrlFormatString="Observation.aspx?Id={0}">
</telerik:GridHyperLinkColumn>

Any ideas why is this?

Thanks!

I have a grid that if it is empty I want to open up an insert form on page load and fill in some default values.

Most of the code works except for this.


Now this works if there is already a record in the grid, but if the grid is empty then it doesn't work.

after this is supposed to fire I am wanting to use the grd.MasterTableView.GetInsertItem() to grab controls and set default values.

Any ideas?

Thanks,

Dustin

Is it possible?? . I trying but I dont get this. Can you help me please.
It is a feature very important for my project.   :(

thank you.

I am trying to set up a RadGrid with multiple dropdownlist filters but I get an ArgumentOutOfRangeException on the MyCustomFilteringColumn 

Here is code from the MyCustomFilteringColumn  
 :
       Protected Overloads Overrides Sub SetupFilterControls(ByVal cell As TableCell)
            MyBase.SetupFilterControls(cell)
            cell.Controls.RemoveAt(0)
            Dim list As New DropDownList()
            list.ID = "list" + Me.DataField
            list.AutoPostBack = True
            AddHandler list.SelectedIndexChanged, AddressOf list_SelectedIndexChanged
            cell.Controls.AddAt(0, list)
            cell.Controls.RemoveAt(1)
            list.DataTextField = Me.DataField
            list.DataValueField = Me.DataField
            list.DataSource = _listDataSource
            list.DataBind()
        End Sub

My RadGrid columns are setup like the below (here is one of the many that I have): 

         <custom:MyCustomFilteringColumn DataField="AssessmentID" FilterControlAltText="Filter AssessmentID column"
             FilterControlWidth="80px" HeaderStyle-Width="80px" ItemStyle-Width="80px" ItemStyle-ForeColor="Black"
                                                HeaderStyle-Wrap="true" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains"
                                                ShowFilterIcon="false" HeaderText="Assessment ID" SortExpression="AssessmentID"
                                                UniqueName="AssessmentID" />


Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        For Each column As GridBoundColumn In RadGrid1.MasterTableView.Columns
            If TypeOf column Is MyStuff.MyCustomFilteringColumn Then
                CType(column, MyStuff.MyCustomFilteringColumn).ListDataSource = GetFilterTable(column.DataField)
            End If
        Next
end sub

    Private Function GetFilterTable(ByVal Field As String) As DataTable
        Dim strConnection As String = ConfigurationManager.ConnectionStrings("PKLConnectionString").ConnectionString
        Dim objConnection As New SqlConnection(strConnection)
        Dim SQLCmd As New SqlCommand() 'The SQL Command
        objConnection.ConnectionString = strConnection     'Set the Connection String
        objConnection.Open() 'Open the connection
        SQLCmd.Connection = objConnection 'Sets the Connection to use with the SQL Command
        Dim dt As New DataTable
        Dim adapter As SqlDataAdapter
        adapter = New SqlDataAdapter("SELECT distinct [" + Field + "] FROM tblAssessment", objConnection)
        objConnection.Open()
        Try
            adapter.Fill(dt)
        Finally
            objConnection.Close()
        End Try
        Return dt
    End Function
