What does this code do (it was in the samples)

My program seems to work fine without it but I am nervous about removing it.

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            if (!e.Item.OwnerTableView.IsItemInserted)
            {
                GridEditableItem item = e.Item as GridEditableItem;

                GridEditManager manager = item.EditManager;

                GridTextBoxColumnEditor editor = manager.GetColumnEditor("CustomerID") as GridTextBoxColumnEditor;

                editor.TextBoxControl.Enabled = false;
            }

        }
    }

DateTimePicker

I am using version 2009.3.1314.35 of the Telerik controls.

When I place a datetimepicker control on an empty form, I am expecting to see a control.SelectedTime property. However, I don't see it.

<

telerik:RadTimePicker ID="RadTimePicker1" runat="server">

</telerik:RadTimePicker>

Inside my designer file, I have the following:

/// <summary>

/// RadTimePicker1 control.

/// </summary>

/// <remarks>

/// Auto-generated field.

/// To modify move field declaration from designer file to code-behind file.

/// </remarks>

protected global::Telerik.Web.UI.RadTimePicker RadTimePicker1;

How can I get this property value to appear in the code behind?

How to handle Enter key in Popup Edit form

In RADGrid, how to make 'Enter' key to accept the change in a popup edit form and return to parent grid control?

What it does now is when I press 'Enter' in a popup edit form, it pops up another edit form for another grid control in the same window. How could that happen?

Go back to top of page after changing selected tab / pageview

I have a page using a master page. The content page includes a tabstrip and multipage combo. I have created a wizard (based on the sample) where the user fills out part of a form and then clicks on a "Next" button to progress to the next pageview. The user can not navigate via the tabstrip and serves only as an indicator of the user's progress towards completing the form.

The tabstrip and multipage are contained in a RadAjaxPanel.

Unfortunately some of the forms in each of the views can be pretty lengthy. When the user clicks on the next button, the pageview changes as desired but it remains scrolled down to the point where the button appeared. How can I make the page scroll back to the top each time the active pageview changes?

Thanks!!!

Radlistbox fires both OnClientItemChecked and OnClientSelectedIndexChanged when an item is checked except in Chrome

Radlistbox fires both OnClientItemChecked and OnClientSelectedIndexChanged when an item is checked in Firefox and IE but not in Chrome.
Chrome seems to have the proper behavior. Is there a reason for this? Can I make IE and Firefox behave accordingly as well?

<telerik:RadListBox ID="radListBox0" runat="server" Height="400" Width="275"

SelectionMode="Single" CheckBoxes="true" Visible="true"

CssClass="RadListBox_SlidingPanel" EnableEmbeddedSkins="False"

EnableEmbeddedBaseStylesheet="False"

OnClientItemChecked="ListBoxIndexCheckToggled"

OnClientSelectedIndexChanged="ListBoxIndexChanged" />

custom number format with ExcelML export

Hi.

I'm trying to get a 1 digit decimal format (ex: 102.4 or 6.0) instead of getting 2 digits (102.41 or 6.02).

protected void gridReport_ExcelMLExportStylesCreated(object source, GridExportExcelMLStyleCreatedArgs e)

{

StyleElement oneDecimalStyle = new StyleElement("oneDecimalStyle");

oneDecimalStyle.NumberFormat.FormatType = NumberFormatType.Fixed;

oneDecimalStyle.NumberFormat.Attributes["ss:Format"] = "0/.0";

e.Styles.Add(oneDecimalStyle);

}

protected void gridReport_ExcelMLExportRowCreated(object source, GridExportExcelMLRowCreatedArgs e)

{

if (e.RowType == GridExportExcelMLRowType.DataRow)

{

CellElement cell = e.Row.Cells.GetCellByName("airDuration");

cell.StyleValue = "oneDecimalStyle";

}

What's wrong in my code?

Right-align, separators and a border

I'm trying to tweak my menu. I have it built and have a sample of what it looks like here:
http://www.crhcf.org/images/menu-sample.jpg

1. Right now the children are left-aligned and I need them right aligned. I'm using images for the 3 child items.

2. How do I define a separator between the child menu items? For instance I'd like to have two small white lines between the 3 child items like this: http://www.crhcf.org/images/menu-sample-2.jpg
Right now it has 3 separators from the body gradient which is not what I want. I don't want a separator under the last item.

3. I would also like to define a border around the entire child menu and make it the same width as the dark green portion of its parent.

How do I do these things? Thanks.

ExportToCSV from HeadreContextMenu

I have been able to export to csv by adding a button to the CommandItemTemplate, then in server side findong the control and setting registerPostBackControl,

Protected Sub RadGrid1_ItemCreated1(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated

....

Dim btn_excel As LinkButton = TryCast(item.FindControl("btn_excel"), LinkButton)

ScriptManager.GetCurrent(Page).RegisterPostBackControl(btn_excel)

....

End Sub

When fired this calls the export and fires correctly prompting the user to view or download.

However I have changed this to now appear as an item in the headerContextMenu, when the user clicks on the export option, the same code fires in the same order, however instead of exporting it just rebinds the data to the grid, the function i use is below,

Sub buildExport(ByVal type As String)

RadGrid1.MasterTableView.Columns.Clear()

Dim boundColumn As GridBoundColumn

For Each column As DataColumn In Datasource.Columns

If GridDataKeyNames <> "" Then

If Not GridDataKeyNames.Contains(column.ColumnName.ToString()) Then

If column.ColumnName.ToString().ToLower().IndexOf("_hidden") < 0 And column.ColumnName.ToString().ToLower().IndexOf("rowclick") < 0 Then

boundColumn = New GridBoundColumn

RadGrid1.MasterTableView.Columns.Add(boundColumn)

boundColumn.DataField = column.ColumnName

boundColumn.HeaderText = column.ColumnName.Replace("_", " ")

Else

boundColumn = New GridBoundColumn

RadGrid1.MasterTableView.Columns.Add(boundColumn)

boundColumn.DataField = column.ColumnName

boundColumn.HeaderText = column.ColumnName

boundColumn.Visible = False

End If

Else

End If

Else

If column.ColumnName.ToString().ToLower().IndexOf("_hidden") < 0 And column.ColumnName.ToString().ToLower().IndexOf("rowclick") < 0 Then

boundColumn = New GridBoundColumn

RadGrid1.MasterTableView.Columns.Add(boundColumn)

boundColumn.DataField = column.ColumnName

boundColumn.HeaderText = column.ColumnName.Replace("_", " ").ToLower()

Else

boundColumn = New GridBoundColumn

RadGrid1.MasterTableView.Columns.Add(boundColumn)

boundColumn.DataField = column.ColumnName

boundColumn.HeaderText = column.ColumnName.ToLower()

boundColumn.Visible = False

End If

Next

RadGrid1.DataSource = Datasource

RadGrid1.DataBind()

RadGrid1.PageSize = Datasource.Rows.Count()

RadGrid1.ExportSettings.IgnorePaging = True

Select Case type

Case "excel"

RadGrid1.ExportSettings.ExportOnlyData = True

RadGrid1.MasterTableView.ExportToCSV()

Case "pdf"

RadGrid1.ExportSettings.OpenInNewWindow = True

RadGrid1.MasterTableView.ExportToPdf()

End Select

End Sub

Like i said boths methods in exporting call the same function, but only the contextItem will work. I am databinding the grid again as the user may have hidden some columns, so this way all coulmns are provided, also needed to remove the boundColumn.DataFormatString = "<nobr>{0:N}</nobr>"
which is created when the grid is loaded to prevent word wrap.

I create the headerMenuItems in the following way

Private Sub addMenuItem(ByVal sender As Object, ByVal e As System.EventArgs)

Dim menu As RadContextMenu = RadGrid1.HeaderContextMenu

Dim item As New RadMenuItem

item.Text = "Save Layout"

item.Value = "save"

item.Attributes("ColumnName") = String.Empty

item.Attributes("TableID") = String.Empty

menu.Items.Add(item)

item = New RadMenuItem

item.Attributes("ColumnName") = String.Empty

item.Attributes("TableID") = String.Empty

item.Text = "Export to CSV"
