[Solved] How to set loading panel next to ajax initiator in master page scenario

How can we make this article: http://www.telerik.com/help/aspnet-ajax/ajxshowloadingpanelnexttoajaxinitiator.html work when using master pages. I placed the code in the linked document in my master page. I surrounded the javascript with radcodeblock markup and changed the 1st line of the javascript to get the client id since i would be calling from a page using a masterpage.

var divElementStyle = document.getElementById('<%= RadAjaxLoadingPanel1.ClientID %>').style;

divElementStyle is populated correctly and i can see all of the styles applied to the loading panel.

When the function gets to:

divElementStyle.left = eventArgs.get_eventTargetElement().offsetLeft + "px";

the get_eventTargetElement failes with the exception "Object Required". I searched the support site for get_eventTargetElement and could not find any additional information. Can anyone provide a workaround?

autopostback onclick

i want to be able to use the itemcommand onclick but i can't do it. here is the scenario. i have a grid declared like this in the default.aspx

<

telerik:RadGrid ID="RadGrid1" runat="server" Width="150"

PageSize="20" AllowSorting="True" AllowMultiRowSelection="False" Skin="Default"

AllowPaging="True" ShowGroupPanel="True" AutoGenerateColumns="false" GridLines="none" OnItemCommand="RadGrid1_ItemCommand">

</telerik:RadGrid>

then in the default.aspx.vb i have a pageload to load the data and column.

RadGrid1.DataSource = "sqlsource1"

Dim boundcolumn As GridBoundColumn

boundcolumn =

New GridBoundColumn

boundcolumn.DataField =

"Department"

boundcolumn.HeaderText =

"Department"

RadGrid1.MasterTableView.Columns.Add(boundcolumn)

RadGrid1.DataBind()

now i want to be able to detect a click on the row click and then open something with the column value like the Auto postback on row click example that you guys have on the web. i could detect the click but it keeps giving me error of "Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"
here is my onclick itemcommand code

Protected

Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand

Thread.Sleep(2000)

If (e.CommandName = "RowClick" AndAlso TypeOf e.Item Is GridDataItem) Then

e.Item.Selected =

True

Dim text As String = "Selected mail ID is: " & e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("MailID")

RadGrid1.Controls.Add(

New LiteralControl(String.Format("<span style='color:red'>{0}</span>", text)))

End If

End Sub

RadDock Code-behind Oddities

Hey all,

Anyone else find it really strange how RadDock's behave when ti comes time for the Post-Back? I followed the example with savelayout, loadlayout to/from the session but after a day of work-around's had to give up... the code was becoming spahgetti and confusing even to me.

I am wondering how everyone else handles post-back's and dock states? I am going to modify my button to do an onclick, then record state with javascript and re-create state server-side in my code-behind.

One serious problem I noticed is that when I start my page, all my RadDocks are in 1 zone to the right, they then are drug onto various zones on left to layout a 'page'. When you save state, all of the zones still think they are in the zone on the right.

Anyone have any advice or clear examples of how to use RadDocks?

Thanks,
Rob

Set Calendar to different month after postback

Hello,

I would like to reset the calendar of the RadCalendar to a different month after page postback. Is it possible to do? By default the RadCalendar reset the Calendar to the current calendar month.

I tried setting the CurrentViewBeginDate and CurrentViewEndDate properties. But it didn't work and i always see the RadCalendar reset to current calendar month.

RadCalendar1.CalendarView.CurrentViewBeginDate = (

DateTime)ViewState["RadCStartDate"];

if(ViewState["RadCEndDate"] != null)

RadCalendar1.CalendarView.CurrentViewEndDate = (

DateTime)ViewState["RadCEndDate"];

Any feedback will be appreciated.

Thanks
Padma

AllowCustomText in ComboBox In Grid

Hello - I have a RadGrid with a GridTemplateColumn, as my code shows below. In this column is a ComboBox, which I want to give users the choice to either choose an existing item or type in a new item. This works if they choose an existing item, but if they type in a new item, when it goes to insert the new row, it loses the value of the custom text. You can see where I am testing it below. What am I missing?

<

telerik:GridTemplateColumn UniqueName="CompanyName" HeaderText="Company Name" DataField="CompanyName">
    <ItemTemplate>
            <asp:Label ID="lblVendorID" runat="server" Text='<%# Eval("CompanyName")%>'></asp:Label>
    </ItemTemplate>
    <EditItemTemplate>
        <telerik:RadComboBox ID="ddlCompanyName" runat="server" DataTextField="CompanyName" DataValueField="CompanyName" MarkFirstMatch="true" SelectedValue='<%# Bind("CompanyName") %>'  DataSourceID="SDSVendorCompany" AppendDataBoundItems="true" AllowCustomText="true">
                <Items><telerik:RadComboBoxItem Text="- Select One -" Value="" /></Items>
        </telerik:RadComboBox>
    </EditItemTemplate>
    <ItemStyle HorizontalAlign="Left" VerticalAlign="Top" /> </telerik:GridTemplateColumn>

I"m testing it here, and if I type in a new value, the value of test is always 'Nothing'. If I choose an existing value, it works great.

Protected Sub SDSVendors_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles SDSVendors.Inserting

Dim test As String = e.Command.Parameters("@CompanyName").Value
