Radgrid EditFormSettings WebUserControl controls null

I have a telerik:RadGrid with inline editing using a user control. The problem is that the user control when examined from inside the OnEditCommand event is always null; although a trace of the asp.net page shows that the controls are rendered.

My Radgrid definition:

<telerik:RadGrid runat="server" AllowPaging="True" ID="grdSPFilters" OnNeedDataSource="grdSPFilters_NeedDataSource"

Width="350px" OnRowDrop="grdSPFilters_RowDrop" AllowMultiRowSelection="false"

OnEditCommand="grdSPFilters_EditCommand" AutoGenerateColumns="false">

My Radgrid edit area definition:

<EditFormSettings UserControlName="FilterMatchRuleBuilder.ascx" EditFormType="WebUserControl">

<EditColumn UniqueName="FilterMatchRuleBuilder01">

</EditColumn>

</EditFormSettings>

My event:

public void grdSPFilters_EditCommand(object sender, GridCommandEventArgs e)

{

// snip...

    GridDataItem item = (GridDataItem)e.Item;

FilterMatchRuleBuilder frb = item.FindControl("FilterMatchRuleBuilder01") as FilterMatchRuleBuilder;

the problem is here - the item.Findcontrol never finds my user control. I've tried enumerating through the entire item.Controls collection and no user controls exist. Although a trace of the asp.NET page shows the user control has been rendered. What is happening here? All the Telerik articles I've seen demonstrate that you simply use an item.Findcontrol; however that simply does not work.

Another thing that doesn't make sense. Inside my grdSPFilters_EditCommand method e.Item.IsInEditMode is always equal to false.

[Solved] How to return a method value as list for RadHtmlChart ?

I'm using a RadHtmlChart based on HTML5 from telerik. I'm using a Pie Chart, and I want to display the method's values. How should I save the values -- maybe as a list? It shouldn't have a big impact on the method itself, because I need this method for some report stuff.

public double GetBookedVacation(int year)
{
    int counter = 0;
    if (this.AnnualVacations.Any())
    {
        foreach (HtVacationDay vacationDay in HtVacationDays)
        {
            foreach (DateTime vacationDayDate in vacationDay.GetDates())
            {
                if (vacationDayDate.Year == year)
                {
                    counter++;
                }
            }
        }
    }
    return counter;
}

Thanks for help and fast answer.

Inconsistent behavior of RadTextbox css class?

I have a RadTextBox on the screen and I am trying to customize the label as illustrated in .http://www.telerik.com/help/aspnet-ajax/input-adding-labels.html. I'm not sure I understand what I'm seeing.

It looks to me like some but not all aspects of the css class are being implemented in the box label. I can set colors but so far I have been unable to set the font size or boldness.

Suggestions?

Adding custom HeaderContextMenuI item

Hi,

I am trying to add a custom HeaderContextMenu item and handle the ItemClick.

Here is my code:

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

GridCGSI_UpdateDefaults(RadGrid1)

AddHandler RadGrid1.HeaderContextMenu.PreRender, AddressOf HeaderContextMenu_PreRender

AddHandler RadGrid1.HeaderContextMenu.ItemClick, AddressOf HeaderContextMenu_ItemClick

End Sub

Protected Sub HeaderContextMenu_PreRender(ByVal sender As Object, ByVal e As System.EventArgs)

Dim menu As RadContextMenu = RadGrid1.HeaderContextMenu

Dim separator As New RadMenuItem()

Dim item As New RadMenuItem()

separator.IsSeparator = True

menu.Items.Add(separator)

item.Text = "Save settings"

item.Value = "SaveSettings"

item.PostBack = True

menu.Items.Add(item)

End Sub

Protected Sub HeaderContextMenu_ItemClick(ByVal sender As Object, ByVal e As RadMenuEventArgs)

End Sub

Public Sub GridCGSI_UpdateDefaults(ByVal tmpGrid As RadGrid)

tmpGrid.CellSpacing = "0"

tmpGrid.AutoGenerateColumns = False

tmpGrid.AllowPaging = True

tmpGrid.PageSize = 40

tmpGrid.AllowSorting = True

tmpGrid.GridLines = GridLines.None

tmpGrid.AllowFilteringByColumn = True

tmpGrid.EnableHeaderContextMenu = True

tmpGrid.ShowStatusBar = True

tmpGrid.HeaderContextMenu.Enabled = True

tmpGrid.MasterTableView.SortExpressions.AllowNaturalSort = False

tmpGrid.AllowMultiRowEdit = False

End Sub

My problem is when I click on my custom item "Save settings" it shows me an asp error of a NullReferenceException:

[NullReferenceException: La référence d'objet n'est pas définie à une instance d'un objet.]
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +147

   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +175
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

Why this is happening?

Thanks.

Silent Install Custom Folder

Hi,

I am trying to deploy VS 2012 Pro and Telerik Dev UI using SCCM 2012.

Is there a commandline syntax for custom install dir. I want to install it to D: instead of normal c:\Program FilesXXXX.

Also will it work for other Dev UI Tools?

Regards

GridNumericColumn in Edit Mode don´t use current culture

    I have a RadGrid with GridNumericColumn. The culture of page is "es-ES" and collate of SQL Server Database is "Modern_Spanish_CI_AI".

    In Spain decimal separator is "," and group separator is ".". RadGrid use culture "es-ES" in ViewMode, but in edit mode I belive that it use default culture.

    For example, in database i have stored the value "0,22" (this value is < 1 and >0, zero comma twenty two) (Sql server datatype => float, equivalent to double in .NET framework). Now:

In ViewMode: appear "0,22" (zero comma twenty two), but
In EditMode: appear "22" (twenty two)

Note: RadGrid use a SqlDataSource standard.
