I have a RadGrid in which I am using GridClientSelectColumn. This column always appears as checkbox no matter what I set in its ButtonType property. How can I change the look of the column to PushButton or LinkButton. I am using 2009 Q1 controls for ASPNET AJAX.

Hi there,

Is there a way to access a particular cell (TD) in radGrid throught javascript?
I need to access the cell, not the content of the cell. I.e I want to change the cell background css etc.
I used to access a normal TD in a table using document.getElementById.
But I noticed radGrid doesn't generate the ID for each cell (TD).
Or maybe I missed something, is there a away to display the ClientID of the Cell / Column for radGrid?

Thanks,

Sxin

Hi All,

I have this problem with the grid on IE8 when UseStaticHeaders, AllowScroll and AllowFilteringByColumn are set to true. It causes the filter fields to be offset to the right when using the Internal Build 1129.35. I don't know if its occurring in earlier builds. It does not occur under IE8 compatibility mode.

I'm using custom variables in my links (as #NAME#, #EMAIL#, #ZIP#, etc.), but the last # is not included (snap01.png). I fix this using Hyperlink Manager Dialog, but when return to editor, and change to HTML view, the symbol # dissapear again.

Thanks for your help.

Hello,

I am having problems with the RadScheduler!  I can drag appointments around and they are saved properly to the database, I am using code behind to a sql table adapter for the update.  I can drag items from a grid onto the scheduler with no problems.  However when I try to edit an appointment I get the following error:

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occured while processing the request on the server. The status code returned from the server was: 500

Once the edit window comes up I can not update or cancel without getting this error.  I thought it was my database parameters so I tried to trap the call to the sql adapter using my own adapter, but it never even hits the adapter.  I tried profiling sql but it never calls into the database.  I tried the AppointmentCommand, AppointmentUpdate, and AppointmentCanceling triggers, but they don't seem to fire.

Can anyone give me an idea as to where to start looking for the problem?

Here is the code for my scheduler



Thanks,

Hi I have this radgrid showing 10 items per page where I want to have a column with checkboxes.
When I check some checkboxes on page 1, I want to go to page 4 and select some more checkboxes.
And then go back to page 1 and the selected checkboxes should still be selected.
I have this working.

Now I want a select all checkbox which selects, well.... All records... I got it so far so it will select all records on the current page, but not on the other pages.

I've set it up like this:

<telerik:radgrid id="RadUsers" allowmultirowselection="true" showfooter="True" runat="server" showstatusbar="True" onneeddatasource="RadUsers_NeedDataSource" gridlines="None" allowpaging="True" pagesize="10" skin="Vista" allowfilteringbycolumn="True" autogeneratecolumns="False" >
    <mastertableview showfooter="True" datakeynames="UserID"  >
        <columns>
            <telerik:gridtemplatecolumn allowfiltering="false">
                <headertemplate>
                    <asp:checkbox id="headerChkbox" oncheckedchanged="ToggleSelectedState" autopostback="True" runat="server"></asp:checkbox>
                </headertemplate>
                <itemtemplate>
                    <asp:checkbox id="cbChecked" runat="server" autopostback="true" oncheckedchanged="OnCheckedChangedEvent" />
                </itemtemplate>
            </telerik:gridtemplatecolumn>
...

And:

        Private ReadOnly Property UsersChecked() As Hashtable
            Get
                Dim res As Object = ViewState("_cc")
                If (res Is Nothing) Then
                    res = New Hashtable
                    ViewState("_cc") = res
                End If
                Return CType(res, Hashtable)
            End Get
        End Property

....

        Protected Sub RadUsers_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadUsers.ItemDataBound
            If TypeOf e.Item Is GridDataItem Then
                Dim item As GridDataItem = CType(e.Item, GridDataItem)
                Dim box As CheckBox = CType(item.FindControl("cbChecked"), CheckBox)
                Dim isChecked As Object = Nothing

                isChecked = UsersChecked(item("UserID").Text)

                If Not (isChecked Is Nothing) Then
                    box.Checked = CType(isChecked, Boolean) = True
                End If
            End If
        End Sub


        Protected Sub ToggleSelectedState(ByVal sender As Object, ByVal e As EventArgs)
            Dim target As Hashtable = Nothing
            target = UsersChecked

            If (CType(sender, CheckBox)).Checked Then
                For Each dataItem As GridDataItem In RadUsers.MasterTableView.Items
                    CType(dataItem.FindControl("cbChecked"), CheckBox).Checked = True
                    'dataItem.Selected = True
                    target(dataItem("UserID").Text) = True
                Next
            Else
                For Each dataItem As GridDataItem In RadUsers.MasterTableView.Items
                    CType(dataItem.FindControl("cbChecked"), CheckBox).Checked = False
                    'dataItem.Selected = False
                    target(dataItem("UserID").Text) = Nothing
                Next
            End If
        End Sub


        Sub OnCheckedChangedEvent(ByVal sender As Object, ByVal e As System.EventArgs)
            Dim box As CheckBox = CType(sender, CheckBox)
            Dim item As GridDataItem = CType(box.NamingContainer, GridDataItem)
            Dim target As Hashtable = Nothing

            target = UsersChecked

            If box.Checked Then
                target(item("UserID").Text) = True
            Else
                target(item("UserID").Text) = Nothing
            End If
        End Sub

I have a grid that has a nested view.  When the parent is expanded depending on the user type I want to hide a column.  I know how to do this for the master table.


but RadGrid2 is a NestedViewTemplate.  When ever I attempt to reference RadGrid2 it tells me it does not exist in current context.  I am assuming I still need to do this in the RadGrid2_PreRender event.

I have a two date pickers on a page. They allow the user to select a from and to date. My page then queries a database and returns all entries within that date range. The page is working fine when you select the date for the first time. However if you change anything and try to submit again the date stays the same as the first time that you picked. Does anyone have any idea why. You can see it here alpha.clickablecommunity.com/printSelect.aspx

Hi,

I have created a web part (which is in fact a smart part where the webpart will load a user control) for a sharepoint site. Inside the user control i have a RadGRid (Rad controls version 2009.1.527.20). Now my problem is that i am constantly getting the exception 'Script control 'RadGrid1' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl' at the following line of code 

_control.RenderControl(writer); Here _control is the user control.

Please let me know how to get around this exception. Also do let me know in case u require anyother info or if i am missing something.

Thanks
Kripa
