Is it possible to ajax the radformdecorator?

I use the code below for my aspx page.

    
            <telerik:RadScriptManager ID="RadScriptManager1" runat="server">  
        
                </telerik:RadScriptManager> 
        
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                </telerik:RadAjaxManager> 
        
                <telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" /> 
        
                skins:<br /> 
        
                <telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="true">  
        
                    <Items> 
        
                        <telerik:RadComboBoxItem Selected="true" Text="Vista" Value="Vista" /> 
        
                        <telerik:RadComboBoxItem Text="Black" Value="Black" /> 
        
                        <telerik:RadComboBoxItem Text="Telerik" Value="Telerik" /> 
        
                    </Items> 
        
                </telerik:RadComboBox> 
        
                <br /> 
        
                <asp:Panel ID="Panel1" runat="server">  
        
                    <asp:Button ID="Button1" runat="server" Text="Button" /><br /> 
        
                    <asp:Button ID="Button2" runat="server" Text="Button" /><br /> 
        
                    <asp:CheckBox ID="CheckBox1" runat="server" /><br /> 
        
                    <asp:RadioButton ID="RadioButton1" runat="server" /><br /> 
        
                    <asp:LinkButton ID="LinkButton1" runat="server">LinkButton</asp:LinkButton><br /> 
        
                </asp:Panel>

and in the code behind I use the code below.

    
            Protected Sub RadComboBox1_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles RadComboBox1.SelectedIndexChanged  
        
                    RadFormDecorator1.Skin = e.Value  
        
                    RadComboBox1.Skin = e.Value  
        
                End Sub  
        
                Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        
                    RadAjaxManager1.AjaxSettings.AddAjaxSetting(RadComboBox1, RadFormDecorator1)  
        
                End Sub

When the user selects a skin from the combobox none of the controls update with its new skin.

I am able to get it to work without using ajax, but then the whole page refreshes. Is it possible to update the controls with the new skin using ajax?

hide command buttons/links issue

I managed it to hides Add New Record button but only the one at the top. The other one at the bottom remains visible :(

    
            if (e.Item is GridCommandItem) 
        
                                { 
        
                                    GridCommandItem cmdItem = (GridCommandItem)RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem)[0]; 
        
                                    ((LinkButton)cmdItem.FindControl("InitInsertButton")).Visible = false; 
        
                                }

Also how do i hide the delete button? I tried the next but it didn't work properly.

    
            if (e.Item is GridDataItem) 
        
                                { 
        
                                    GridDataItem item = (GridDataItem)e.Item; 
        
                                    LinkButton editButton = (LinkButton)item.FindControl("EditButton"); 
        
                                    editButton.Visible = false; 
        
                                    //LinkButton deleteButton = (LinkButton)item.FindControl("DeleteButton"); 
        
                                    //deleteButton.Visible = false; 
        
                                }

the Edit button gets hidden but the delete throws an exception "Object reference not set to an instance of an object".

RadWindow with ContentTemplate inside RadUpdatePanel

Hi everyone...

Consider my code below:

<telerik:RadWindow ID="radwdwAddressDetails" runat="server" Modal="true" Behaviors="None"

OpenerElementID="<%# btnShowAddressDetails.ClientID %>" Width="350px" DestroyOnClose="false">

<asp:Panel ID="pnlAddressDetails" runat="server" CssClass="popup-outer">

<uc:AddressDetails ID="ucAddressDetails" runat="server" />

<asp:Button ID="btnOKAddressDetails" runat="server" Text="+ Add" CssClass="button green"

CausesValidation="true" OnClick="btnOKAddressDetails_Click" />

<asp:Button ID="btnCancelAddressDetails" runat="server" Text="Cancel" CssClass="button red"

CausesValidation="false" />

</div>

</asp:Panel>

</ContentTemplate>

</telerik:RadWindow>

This code is part of another user control. The form hosting these controls wraps them in a RadUpdatePanel.

Currently, clicking on btnOKAddressDetails causes a full post pack refreshing the entire page which is not desirable (as it is inside the update panel). I would like it to do an asynchronous post back in this regard.

Any ideas?

cancel all current requests

I am using xmlhttppanel with a grid and mouseover events. if the user quickly mouses over a bunch of items, it queues up the requests, and performs them one at a time. I'd like to be able to cancel all current requests, that have already been made through panel.set_value

SelectedIndexChanged Event on dropdown results in closing Edit mode

I need to hide some input cols when the value changes in a a dropdownlist in edit mode. I added a SelectedIndexChanged event in the Item_Created for the dropdownlist. The event fires when I change the dropdown but then it leaves edit mode. I think the issue is I have to set the autopostBack to true on the list, but if I don't set it to true it won't fire when I change the value in the list.

Is there another way to implement this?

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode && e.Item.OwnerTableView.Name == "DeviceDetail")

{

//the dropdown list will be the first control in the Controls collection of the corresponding cell

DropDownList list = (e.Item as GridEditableItem)["DeviceTypeDropDown"].Controls[0] as DropDownList;

list.AutoPostBack =

true;

list.SelectedIndexChanged +=

new EventHandler(DeviceTypeIndex_Changed);

}

void

DeviceTypeIndex_Changed(Object sender, EventArgs e)

{

DropDownList list = sender as DropDownList;

GridEditableItem editedItem = (sender as DropDownList).NamingContainer as GridEditableItem;

if (((DropDownList)sender).SelectedItem.Text == "Device1")

{

editedItem[

"isDeviceAdjacent"].Controls[0].Visible = true;

}

else

{

editedItem[

"isDeviceAdjacent"].Controls[0].Visible = false;

}
