Readonly node

Hi Telerik

I'm trying to get at node i a treeview to behave as normal, but the user must not be able to change the nodes checked state.
Is it posible to make a node "ReadOnly" but behave as normal?

I've made a small test project to show that i'm looking for.

Hope you understand my problem.

RadScheduler Update problem with master page.

I have an application with master page, I placed rad-scheduler under RadAjaxPanel on my content page with ScriptManager/RadScriptManager. When I insert any appointment it works fine but when i update any appointment it does not work, it fails to update.
Similarly when I do the same work in my simple ASPX page without any master page it works fine for me.
In both case i use SQLDataSource wizard to select,insert,update and delete from RadScheduler.

Please help me out I am stuck.
Urgent response is appreciated

Regards,

Problem with VSB and IE8

Hi all!
Hope this is the right section of the forum for my question.
I'm trying to build a custom skin using the Visual Style Builder. It's the first time I use custom skins so forgive me if that's a dumb question but I'm going nutty.
The problem is that when viewed in Firefox everything works almost fine (I still have to change something that can't be changed using this awesome tool so I have to edit the default sprite), instead everything gets screwed up when viewed in IE8. You can find attached herewith two screenshots: one showing the skin rendered in IE 8, the other showing the screen rendered in Firefox 4.
I can't find out why.

Thanks in advance,
Daniele Salatti

RADGrid with User Control Edit Form and SQLDataSource

Hi,
I'm searching the web for several days but couldn't find a solution yet.
What I want to do is to use the RADGrid with User Control Edit Form for insert and update. And I want to use SQLDatasource to reduce the code for insert/update operations. Displaying the data from the grids selected item in the user control works fine. But I have problems to insert and update records using the SQLDatasource with parameters. Seems that the insert/update events are not fired.

Is it possible to use SQLDataSource for update/insert when using a user control in RADGrid? Are there any samples for that available?

Thanks for your help.

Read RadGrid CheckBox if checked or not and other values from RadGrid

ok I have RadGrid implemented, it works great and I can see my data
I implemented a checkbox control on that grid

<telerik:GridTemplateColumn HeaderText="Select" UniqueName="AssetId">

<ItemTemplate>

<asp:CheckBox ID="CheckBox1" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>

Now I have a button on the page, under its click event I want to read all the rows which are checked
I am doing something similar but its not working.
I am unable to check the checkbox is checked or not.

protected void UpdateButton_Click(object sender, EventArgs e)

{

for (int i = 0; i < RadGrid1.MasterTableView.Items.Count; i++)

{

bool isChecked = ((CheckBox)RadGrid1.MasterTableView.FindControl("CheckBox1")).Checked;

if (isChecked)

{

Label lbl = ((Label)RadGrid1.FindControl("lblRadItemId")) as Label;

LabelValue = ((Label)RadGrid1.Rows[i].Cells[8].FindControl("lblRadItemId")).Text;

}

Selected Item Disappears

Hello,

For a ComboBox like this:

<telerik:RadComboBox ID="Persons" runat="server" DataTextField="Name" DataValueField="Id" MarkFirstMatch="true" AppendDataBoundItems="true">

<Items>

<telerik:RadComboBoxItem runat="server" Value="0" Text="" />

</Items>

</telerik:RadComboBox>

When I select an item then click somewhere else, the combobox seems to reset or clear the selection. This is happening with various comboboxes on my page.

How can I get the selected item to stay where it should? There is no postback or anything. This happens on the client side and the control binds with data with no issue.

Telerik radgrid attaching oncommand client event messes up paging

I have a telerik radgrid with paging enabled and attaching the oncommand client event messes up paging.
Without the oncommand event, I am able to click on page numbers on the pager and it properly shows the selected page number text in bold.
But if I attach a oncommand event, it does not highlight the selected page number at all. And all the page numbers remain as hyperlinks including the selected page. Here is the sample code to reproduce this issue. Can some one please let me know if there is a fix ? I need to be able to trap the commands and cancel them if possible before postback happens to the server. And pagination is very critical for me as well. I tried to attach the oncommand event handler in the server side code(on page load event) but it doesnt help.

<telerik:RadCodeBlock ID="RadCodeBlock2" runat="server">

<script type="text/javascript">

function onInqGridCmd(sender, eventArgs) {

}

</script>

</telerik:RadCodeBlock>

<telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" EnableEmbeddedSkins="true" Skin="Gray" AllowSorting="True"

AllowPaging="True" PageSize="5" runat="server" GridLines="None" Width="100%">

<PagerStyle Mode="NextPrevAndNumeric"></PagerStyle>

<ClientSettings>

<Scrolling AllowScroll="true" SaveScrollPosition="true" UseStaticHeaders="true" />

<ClientEvents OnCommand="onInqGridCmd"></ClientEvents>

</ClientSettings>

</telerik:RadGrid>

<asp:SqlDataSource ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"

ProviderName="System.Data.SqlClient" SelectCommand="SELECT CustomerID, CompanyName, ContactName, ContactTitle, Address, PostalCode FROM              Customers" runat="server"></

asp:SqlDataSource>

Appreciate your help.

Prevent flashing on custom command click.

Hi all,

I have a custom command created like so:

DockCommand settingsCommand = new DockCommand();

settingsCommand.Name = "Local Settings";

settingsCommand.Text = "Local Settings";

settingsCommand.CssClass = "LocalSettings";

settingsCommand.AutoPostBack = false;

settingsCommand.OnClientCommand = "ShowLocalSettings";

Commands.Add(settingsCommand);

function ShowLocalSettings(sender, eventArgs) {

radDock = sender;

var oWindow = window.radopen(null, "LocalSettingsWindow");

oWindow.center();

}

The RadWindow appears fine and everything works as expected, but, in the background I can see my page refreshing when I click the custom command button -- even though autopostback is set to false. My RadWindow doesn't flash, and it's modal so the background can't be interacted with, but it is still distracting to see it refreshing once when my RadWindow is already displayed.

Any ideas on why this would be happening?
