GridDropDownColumn selectedIndexChanged event stop firing after applying RequiredFieldValidator

Hi, I hope I can explain my problem clearly.

I have RadGrid with two GridDropDownColumns and some other RadNumericTextBox columns.

One of the GridDropDownColumn is filtered based on the selected value from the other GridDropDownColumn.

I was able to fire SelectedIndexChange event at this point. The event stop firing after I applies RequiredFieldValidator on one of my RadNumericTextBox.

When the grid is in edit mode, everything is fine if I just select the combobox to filter the other one, However, once I try to update and it failed because of RequiredFiedValidator. The combobox' selectIndexChange event can not be fired anymore.

My code are following
ASCX

<Columns>

<telerik:GridDropDownColumn UniqueName="Combo1" DropDownControlType="RadComboBox" DataField="Combo1data" DataSourceID="odcCombo1" ListValueField="Description1" ListTextField="Description1" ColumnEditorID="edtCombo1" HeaderText="Main" HeaderStyle-Width="120px" ItemStyle-Width="120px"></telerik:GridDropDownColumn>

<telerik:GridDropDownColumn UniqueName="Combo2" DropDownControlType="RadComboBox" DataField="Combo2data" DataSourceID="odcCombo2" ListValueField="Description2" ListTextField="Description2" ColumnEditorID="edtCombo2" HeaderText="Depend" HeaderStyle-Width="100px" ItemStyle-Width="100px"></telerik:GridDropDownColumn>

<telerik:GridTemplateColumn UniqueName="NumData1" DataField="Data1" ItemStyle-ForeColor="Black" HeaderText="NumData" ItemStyle-Width="55px" HeaderStyle-Width="55px" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" >

<ItemTemplate>

<asp:Label runat="server" ID="lblData1" Text='<%# Eval("Data1", "{0:C}") %>'></asp:Label>

</ItemTemplate>

<EditItemTemplate>

<span><telerik:RadNumericTextBox runat="server" ID="tbData1" Width="55px" DbValue='<%# Bind("Data1") %>' MinValue="10000000" MaxValue="99999999" MaxLength="8"><NumberFormat DecimalDigits="0" GroupSeparator="" />

</telerik:RadNumericTextBox><span style="color: Red"><asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="tbData1" ErrorMessage="*" runat="server"></asp:RequiredFieldValidator>

</span>

</EditItemTemplate>

ASCX.CS

protected void grdTimeCard_ItemCreated(object sender, GridItemEventArgs e)

{

//create fire event when it's in edit mode

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

GridEditableItem editItem = (GridEditableItem)e.Item;

GridDropDownListColumnEditor editor = (GridDropDownListColumnEditor)editItem.EditManager.GetColumnEditor("Entry");

editor.ComboBoxControl.AutoPostBack = true;

editor.ComboBoxControl.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(list_SelectedIndexChanged);

}

private void list_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

}

protected void grdTimeCard_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

string defaultCombo1 = "";

GridDataItem dataItem = e.Item as GridDataItem;

GridEditableItem editItem = (GridEditableItem)e.Item;

//do nothing if it's insert itme

if (e.Item is GridDataInsertItem)

{

}

else

{

// if it's edit mode

defaultCombo1 = ((DataRowView)e.Item.DataItem)["Combo1"].ToString();

try

{

RequiredFieldValidator validator1 = (RequiredFieldValidator)editItem.FindControl("RequiredFieldValidator1");

if (defaultCombo1 == "Regular" )

validator1.Enabled = true;

else

validator1.Enabled = false;

Any suggestions?

Tab Strip/Multi Page is killing me... :(

I'm the first to admit I'm not as experienced as many but still, I can't believe it's so hard to get the tab strip / multi page setup working properly. Can anyone give me am "Idiot's Guide" to common mistakes? I have what should be simple enough: 3 tabs, 3 page views. Initially the problem was that when you first loaded the page, although the correct tab was selected, it showed the wrong page view until your first tab change which I assume fired a post back that got everything "sync'd up". I tried various settings for things like index and moved the tab hierarchy around. Now the correct tab and it's correct pageview show when the page is loaded but one tab will not show it's corresponding pageview at all. I've checked everything I can think of... all the page views are registered with their corresponding tabs, the tabs show and seem to select properly but one page view has "vanished".

Arghhhhhhhhhhhhhhhhhh....

How to disable/hide the navigation buttons after selecting SHOW ALL in RadGrid Paging

I've added the "ALL" option to the PageSizeComboBox in RadGrid.
Very similar to this option: http://www.telerik.com/community/forums/aspnet/grid/how-to-add-show-all-option-in-radgrid-paging.aspx#1697877

Everything works fine, but when I select 'ALL', the navigation buttons are there.
Unfortunately, when I click on them, they crash my website.

Is it possible to disable or hide the navigation button in RADGrid Paging when the 'ALL' option is selected?
How can I access the navigation buttons in the server side code.
I tried using this as somebody in some other thread had mentioned in Item_Created Event:
if (e.Item is GridPagerItem) Button prev = ((Button)e.Item.FindControl("Button1"))
But it doesnt work. Please help.
