When I scroll to a raddock from javascript the dock is collapsed and can't be expanded.
I tried all these functions (window.location.href, scroll(" "), $(" ").scroll())
but the problem resist only with Lightweight render.
The only solution is <a href="#Dock_ID" > but I really need it as javascript command because it's a general function not static ID's in <a> tags

GridTemplateColumn inside a CompositeControl

Hello, I am trying to follow this sample

http://www.telerik.com/help/aspnet-ajax/grid-programmatic-creation.html

to create a template grid column in a grid that in my case is contained inside a CompositeControl

First attempt, using the control OnInit event

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

EnsureChildControls();

…

if (!Page.IsPostBack)

{

    var boundColumn = new GridBoundColumn();

  grid.MasterTableView.Columns.Add(boundColumn);

    boundColumn.DataField = "MyColumn";

GridTemplateColumn templateColumn = new

GridTemplateColumn(); 

grid.MasterTableView.Columns.Add(templateColumn);

templateColumn.ItemTemplate = new MyTemplate(templateColumnName);

}

Result: the InstantiateIn method of the template is called only the first time, but in postbacks not.

Second attempt: subscribing to the page Init event

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

EnsureChildControls();

Page.Init += PageInit;

…

private void PageInit(object sender, EventArgs e)

{



var boundColumn = new GridBoundColumn();

  boundColumn.DataField = "MyColumn";

grid.MasterTableView.Columns.Add(boundColumn);

    GridTemplateColumn templateColumn = new GridTemplateColumn();

templateColumn.ItemTemplate = new

MyTemplate(templateColumnName);

grid.MasterTableView.Columns.Add(templateColumn);

Result: the template column is correctly created, but the bound one is duplicated on every postback

What's the correct way to programmatically create a template column in a composite control?
Thanks

multple static header grid column alignment in IE compatibilty mode

Hi Team,

I am using telerik version 2013.2.611.35 for asp.net ajax controls.

I am having problems with IE-compatibility mode for radgrid with multiple headers, static header.
I have attached 2 images. One in normal IE9 mode and the other in IE-compatibility mode. As seen in the images in IE-compatibility mode the header columns and data columns are mis-aligned.

I also tried meta tag "<meta http-equiv="X-UA-Compatible" content="IE=edge"/>", but no use.

Please provide a possible solution.

Show picture for selected item of a CustomFilter combobox

Hello,

I have a grid with a customfilter column that lets filter choosing in a combobox that shows images (I'm using sprites, and the image is set through cssclass).

Here is the Custom filter class:

Public Class SeleccionFilteringColumn

Inherits GridTemplateColumn

Protected Overrides Sub SetupFilterControls(ByVal cell As TableCell)

Dim rcBox As New RadComboBox()

rcBox.Width = 55

rcBox.ID = "DropDownListSeleccion"

AddHandler rcBox.ItemCreated, AddressOf rcBox_ItemCreated

rcBox.AutoPostBack = True

rcBox.Items.Add(New Telerik.Web.UI.RadComboBoxItem("", -1))

rcBox.Items.Add(New Telerik.Web.UI.RadComboBoxItem("", 0))

rcBox.Items.Add(New Telerik.Web.UI.RadComboBoxItem("", 1))

AddHandler rcBox.SelectedIndexChanged, AddressOf rcBox_SelectedIndexChanged

cell.Controls.Add(rcBox)

End Sub

Protected Overrides Sub SetCurrentFilterValueToControl(ByVal cell As TableCell)

If Not (Me.CurrentFilterValue = "") Then

Try

DirectCast(cell.Controls(0), RadComboBox).Items.FindItemByValue(Me.CurrentFilterValue).Selected = True

Catch ex As Exception

End Try

End If

End Sub

Public Overrides Property Visible As Boolean

Get

Return MyBase.Visible

End Get

Set(value As Boolean)

MyBase.Visible = value

End Set

End Property

Protected Overrides Function GetCurrentFilterValueFromControl(ByVal cell As TableCell) As String

Dim currentValue As String = DirectCast(cell.Controls(0), RadComboBox).SelectedItem.Value

Me.CurrentFilterFunction = If((currentValue <> ""), GridKnownFunction.EqualTo, GridKnownFunction.NoFilter)

If currentValue = "-1" Then Return Nothing

Return currentValue

End Function

Private Sub rcBox_SelectedIndexChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs)

DirectCast(DirectCast(sender, RadComboBox).Parent.Parent, GridFilteringItem).FireCommandEvent("Filter", New Pair())

Select Case e.Value

Case 0

CType(sender, RadComboBox).InputCssClass = "btnNoSeleccionado"

Case 1

CType(sender, RadComboBox).InputCssClass = "btnSeleccionado"

End Select

End Sub

Protected Sub rcBox_ItemCreated(o As Object, e As RadComboBoxItemEventArgs)

e.Item.Height = 34

Select Case e.Item.Value

Case 0

e.Item.CssClass = "btnNoSeleccionado"

Case 1

e.Item.CssClass = "btnSeleccionado"

End Select

End Sub

End Class

You can see the filter combobox open in the attached image. How can I do the selected picture to will be shown in the input combobox? I've tried to assign the InputCssClass in the SelectIndexChanged event but it didn't work.

Thank you

Roberto

Change Grid Font Size

OK, this seems like this should be a piece of cake. I want to change the font of the entire grid (headers, items, etc) to use a font size of ".8em;". I have changed the font size at the grid level and nothing changed. I am able to override individual columns with the item styles. Isn't there an easier way to do this?

Return text value of checked button

I have a toolbar that is dynamically created server side. Client side, I'm trying to determine which button is currently clicked and capturing the text value of the button. One of the buttons is definitely checked but I never return a value. What am I doing wrong?

function RowDblClick(sender, eventArgs) {

var toolBar = $find("<%=radtoolMonths.ClientID%>");

var intMonths = toolBar.get_items().get_count();

var datMonth='1/1/14'

for (var i = 0; i < intMonths; i++)

{

if (toolBar.get_items().getItem(i).get_checked == true) {

datMonth = toolBar.get_items().getItem(i).get_text;

}

                                    </telerik:RadComboBox>

and the second will be filled based on the selected value of first one. And here we are always getting cbo1.SelectedValue is empty.
but i am able to get the value here on the "OnClientBlur" event of cbo1.

function OnClientBlurAdd(sender, eventArgs)
    {
         myMultipleParametersHandlerAdd(sender, eventArgs);
    }

    function myMultipleParametersHandlerAdd(combo, eventArgs)
    {
        var item=combo.get_highlightedItem();
        if(item !=null)
        {
            combo.set_text(item.get_text());
            combo.set_value(item.get_value());     ///i am able to get the value here
        }
        else
        {
            combo.clearSelection();
            combo.set_emptyMessage("Select One");

        }
    }

what can be the issue?

Thank you,
Saranya.

Radtabstripe TabClickEvent

Hi,

I'm using a rad tab strip with an on TabClickEvent. I've ajaxified this process and that all works but the problem is when I select a new tab the page view doesn't change. The initial page view which is RadPageView1 is always visible regardless of the tab that is selected. I didn't have this problem before using the TabClick server event. Am I doing something wrong? Here's the code...

<telerik:RadTabStrip ID="radTabStrip1" runat="server" Skin="MetroTouch"

MultiPageID="RadMultiPage1" Width="832px" BorderStyle="None" SelectedIndex="0"
