RadTextbox loses focus on AutoPostback in a usercontrol

I have a user control with some RadTextboxes, RadNumericTextboxes, RadComboBoxes. I have this usercontrol on an aspx page which has the RadAjaxManager. I have a requirement to maintain if the controls in the usercontrol have changes, so, I have set the AutoPostBack property to true and on postback, I set ViewState["NameIsDirty"]=true; But my problem is, when the user updates the Name and clicks on tab, the cursor goes to the next control and immediately disappears! Seems like it is getting focussed on the first control on the page. If I dont have the AutoPostBack property set to true, the focus is on the next control and everything is fine. How do I make the focus stay on the control on which it is supposed to be. I searched the forums and tried a few solutions, but they did not work.
I have tried this and it doesnt work:

protected void rdtCCno_TextChanged(object sender, EventArgs e)

{

ViewState["NumberIsDirty"] = true;

string script =string.Format(@"window.setTimeOut(function(){{$find('{0}').Focus();}},10);",rdtCvv2.ClientID);

ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), "mykey", script,true);

}

protected void rdcExpMonth_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)

{

ViewState["ExpMonthIsDirty"] = true;

var rdAjaxManager = RadAjaxManager.GetCurrent(this.Page);

if (rdAjaxManager != null)

{

rdAjaxManager.FocusControl(rdtAddr1);

}

RadListView databinding with entity framework - insert/update/delete

I am trying to create an ASP.NET page to allow basic CRUD operations using Entity Framework. Using Telerik's RadListView, I have the following HTML:

<telerik:RadListView ID="RadListView1" runat="server" OnNeedDataSource="RadListView1_NeedDataSource">

<ItemTemplate>

<table>

<tr>

<td>First Name:

<%#Eval("FirstName")%>

</td>

</tr>

<tr>

<td>

<asp:Button ID="btnEdit" runat="server" Text="Edit" CommandName="Edit" Width="70px"></asp:Button>

</td>

</tr>

</table>

</ItemTemplate>

<EditItemTemplate>

<table>

<tr>

<td>First Name:

<asp:TextBox ID="txtFirstName" runat="server" Text='<%#Bind("FirstName")%>'></asp:TextBox>

</td>

</tr>

<tr>

<td>

<asp:Button ID="btnUpdate" runat="server" Text="Update" CommandName="Update" Width="70px"></asp:Button>

</td>

</tr>

</table>

</EditItemTemplate>

And here is the code behind:

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

         RadListView1.DataSource = GetData();

}

protected void RadListView1_NeedDataSource(object sender, Telerik.Web.UI.RadListViewNeedDataSourceEventArgs e)

{

RadListView1.DataSource = GetData();

}

private List<Person> GetData()

{

using (BuildingAccessEntities ctx = new BuildingAccessEntities())

{

var query = from a in ctx.People

orderby a.FirstName

select a;

return query.ToList();

}

So far, this code properly displays the populated RadListView. When I click the Edit button, the RadListView switches to Edit mode and allows me to Edit the selected record; however, when I click the Update button to save the record, the changes are not saved.

I have not yet tried to see if inserts and deletes behave this same way.

I'm sure 2-way binding should be something very simple with the RadListView, but I am new to this and have not been able to find many examples to make this work other than by using data source controls (SqlDataSource, EntityDataSource, etc.).

Any assistance will be greatly appreciated!

Hierarchy RadGrid - clientside reordering columns, reorder detail table reorders mastertable

Hi there,

I'm having a problem with my hierarchical radgrid. When I expand the details table and try to reorder the table with ReorderColumnsOnClient = "True", the masterTable gets reordered as well. For example, if I have move the column in position 1 and switch it with column 2 on the details table, column 1 and column 2 are switch on the master table as well. This also happens for a 3 level hierarchy except it does not affect the first details table if the second detail table has been reordered, only the master table (i.e. switching column 1 and column 2 on the 2nd detail table (innermost) ONLY switches column 1 and 2 on the master table, NOT the first (outer) detail table).

Any ideas?

Thank you,

Tom

Auto or Lightweight Rendering mode breaks RadComboBox Drobdowns

Switching from Classic to Auto or Lightweight render mode (e.g. "Telerik.Web.UI.RenderMode" value="Classic" --> "Telerik.Web.UI.RenderMode" value="Auto") seems to cause a break in most places where RadCombo box is used.
What about Lightweight/Auto rendering could be causing this?

Please refer to screenshots.

Any and all theories and/or suggestions will be greatly appreciated.

Google and Multi-Select Filtering

I have implemented the "Google-Like" filtering in my RadGrid. I have read about including checkboxes in the radcombobox drop down list for filtering purposes. Is it possible to also have the "multi-select" filtering functionality as well, and how would this be implemented?

Thanks,
Mark
