How to dynamically set child tab as selected

Hi -- We have a RadTabStrip control with few tabs. Under most tabs there are sub-tabs. We want to dynamically select a tab when the page loads. Based on this selected tab, the sub-tab should be selected. I know how to set the tab as selected on the main tab but not having much luck with setting the child tab.

So, for our example, I am setting the third tab on main tab strip as selected when the page loads. This part works.
Now I want to set the 5th child tab of this selected tab as highlighted. Can't figure out how to do it.

What's happening is that the third tab on main shows up as highlighted. However it is showing the child tabs of first tab below it.

Can someone please help?

Thanks

Hooking up CheckBox in GridTemplateColumn to AsyncPostBackTrigger

I've been scouring the threads for an example like mine and I've found bits and pieces, but haven't been able to put everything together to get what I want to work. What I have is a grid with a checkbox in the first column that I want to perform an action on check changed. I also have a button in the last column that puts the grid into edit mode. Around everything I have an UpdatePanel.

My problem is setting my triggers for only the checkbox on checkchanged. I can set children as triggers, but that will cause the other button to trigger which I don't want. I tried trying to programaitcally add the trigger in the ItemCreated event, but to no avail.

Relevant code as followed.

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<ContentTemplate>

<rad:RadGrid ID="rg" OnUpdateCommand="Update" OnNeedDataSource="BindItems" OnItemDataBound="rg_ItemDataBound" OnPreRender="rg_PreRender" runat="server" >

<PagerStyle Position="Top" />

<MasterTableView DataKeyNames="ID" CommandItemDisplay="None">

<CommandItemTemplate>

<asp:ImageButton ID="ImageButton1" ImageUrl="/admin/images/add-record.jpg" CommandName="InitInsert" runat="server" /> Add New

</CommandItemTemplate>

<Columns>

<rad:GridTemplateColumn HeaderStyle-Width="40px" HeaderText="Email">

<ItemTemplate>

<asp:CheckBox id="cbEmail" AutoPostBack="true" OnCheckedChanged="AddToEmailList" runat="server" />

</ItemTemplate>

</rad:GridTemplateColumn

>

                                          // a handful of other columns

<rad:GridEditCommandColumn EditText="More" HeaderStyle-Width="30" />

</Columns>

</MasterTableView>

</rad:RadGrid>

</ContentTemplate>

</asp:UpdatePanel>

Again, I want to only asynchronously postback when that checkbox is checked. Thanks for any help in advance.

Combobox with checkbox, oncheckbox selected combo text is not updated in Chrome

Hi,

I am using combobox with checkbox for multiple selection. I am showing the selected text on checkbox selection and saving the selections next time that will be auto select. this is working fine in IE7,IE8 and mozila. But not working in Chrome. It showing error that "Uncaught TypeError: Cannot call method 'set_text' of null".

The code is as below when i am showing the selected text on the basis of previous selection

javascript:setTimeout("$(document).ready(function() { SetHeaderComboText('ucSearchBuilder_grdFilter_ctl00_ctl06_ddlFilterHeaderwithTreeView','Conflict Resolution');});",100);

comboIds is redcombobox id and values are text to be display in radcomdobox

function SetHeaderComboText(comboIds, values) {

    var arrcomboId = comboIds.toString().split('<');

    var arrvalue = values.toString().split('<');

    for (var j = 0; j < arrcomboId.length; j++) {

        var comboId = arrcomboId[j];

        var text = arrvalue[j];

        var comboBox = $find(comboId);

        //set the text of combobox

        if (text.length > 0) {

            //set the text of the combobox

comboBox.set_text(text);

}

        else {

            //all checkboxes are unchecked so reset the controls

            comboBox.set_text("");

Sorting a RadGrid with IEnumerable<T> and yield keyword

Why doesn't sorting work when you bind an IEnumerable<T> collection that uses the yield keyword? Do I have to implement a custom paging solution? I am using 2012 Q1 SP1 controls.

<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource">

<MasterTableView AllowSorting="true" AllowPaging="true" PageSize="20" AllowFilteringByColumn="true" />

</telerik:RadGrid>

using System;

using System.Collections.Generic;

using System.Configuration;

using System.Data;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.HtmlControls;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Data.Linq;

using System.Linq;

using Telerik.Web.UI;

public class Class1

{

public Class1(int i)

{

this.Column1 = i.ToString();

this.Column2 = (200 - i).ToString();

this.Column3 = System.Text.Encoding.Default.GetString(new[] { System.Convert.ToByte(65 + (i % 26)) });

}

public string Column1 { get; set; }

public string Column2 { get; set; }

public string Column3 { get; set; }

public static IEnumerable<Class1> GetData()

{

List<Class1> data = new List<Class1>();

for (int i = 0; i < 200; i++)

{

yield return new Class1(i);

}

public partial class Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

//RadGrid1.DataSource = Class1.GetData().ToArray(); //works

RadGrid1.DataSource = Class1.GetData(); //doesn't work

}

"Not a registered script control" error when using RadMenu inside RadComboBox and setting MinFilterLength

Hello,

I am trying to embed a RadMenu inside a RadComboBox. Everything works fine until I try to configure the combobox to request items only after at least three characters have been entered into the filter. Once I set the EnableAutomaticLoadOnDemand to "true" I get the error attached.

My code is below. Please advise on possible steps to resolve this issue.

<telerik:RadComboBox ID="RadComboBox4" runat="server" Width="590px" Height="140px"

Filter="Contains" ShowToggleImage="False" EmptyMessage="Fund..." MinFilterLength="3" EnableAutomaticLoadOnDemand="True"

DataSourceID="SqlDataSource1" DataTextField="Name" DataValueField="FundID"

OnItemDataBound="RadComboBox4_ItemDataBound" >

<ItemTemplate>

<div style="float: left">

<asp:Label ID="Label1" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Name") %>'></asp:Label>

</div>

<div style="float: right">

<telerik:RadMenu ID="RadMenu1" runat="server" EnableRoundedCorners="true" EnableShadows="true" >

<Items>

Icon Issue on Hierarchy Grid

I copied your demo "Grid /Update/Insert/Delete In Hierarchy" aspx and vb code into a solution I created for using a custom skin. I have an aspx page with a number of your controls so I can see how they will look with my custom skin DLL. What I am seeing with this multi-level grid is the icons don't always show up. Sometimes all I get is the empty box with an "X" and the text default for the icon. This not only happens with my custom skin but with the canned skins from Telerik. I may have to do several screen refreshes to get the icons to show. I can't figure out what is causing this to happen. If you want my solution, let me know and I will open a support ticket so I can send you a zip file.
