Hi,
I have the below code in Itemcommand. I want to restrict users to enter only 2 rows. And also, if an existing row is deleted and number of rows is within 2, user should be able to add new item. This code is not working

int count = radgrid1.MasterTableView.Items.Count;

if (count > 2)

{

e.Canceled = true;

radgrid1r.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.None;

}

else

{

radgrid1.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.TopAndBottom;

}

Also, i am clicking on "ADD NEW ITEM" twice to make it disapper.
If the items inserted are 2 then automatically the "add new item" should not be displayed.
How to fix this?

EnableAutomaticLoadonDemand and caching

I tried the EnableAutomaticLoadonDemand technique and it works basically well. One thing though, I thought it was supposed to cache the full result from the database if I set EnableItemCaching. I ran a SQL Profiler trace and it reruns the query each time, which causes slowness in non-local situations. The combo does need to post after the user selects something, so the app can continue with the selection they chose. Is there something else I need to do?

Thanks.

<telerik:RadComboBox ID="CaseRadComboBox" runat="server" DataSourceID="CaseSqlDataSource" DataTextField="FullCaseName" DataValueField="subIdx" enableautomaticloadondemand="true"

enablevirtualscrolling="true" itemsperrequest="15" Filter="Contains" Width="400px" AutoPostBack="True" enableitemcaching="True" >

</telerik:RadComboBox>

How to Set Custom Text after Item is Selected?

I have a simple 2-column RadComboBox which I'm using strictly as a dropdown listbox. It's generally working fine except I'd like to do one more thing with it. After an item is selected then the short Description text (ex. "228", "3900", "850", etc.) is shown in the RadComboBox after it collapses.

But what I'd like to do is display the related text as a suffix. So, for example, if the first item is selected then rather than just display "228", instead I'd like to display "228 (601-10101 / 4000)".

I tried doing this by setting the RadComboBox's Text property but this failed to achieve it. I then also tried setting the EmptyMessage property but that didn't work either.

Is there a way I can do it?

Error adding items manually

Hi there,

I am struggling to insert items to the RadComboBox.

I use the following code

protected

void cbLocation_DataBound(object sender, EventArgs e)

{

//fill radcombobox

cbLocation.Items.Clear();

cbLocation.Items.Insert(0,

new RadComboBoxItem("<Make choice>", ""));

cbLocation.Items.Insert(1,

new RadComboBoxItem("EPO", "EPO"));

cbLocation.Items.Insert(2,

new RadComboBoxItem("PDC", "PDC"));

}

I get the following error when I click the Update or Cancel button in the Edit form:
Error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

Do you have any idea why the error occurs?

Thanx!

Close radcombobox on click input area

Is it possible to configure the radcombobox so it collapses when one clicks on the input area?
It opens when you click there, but won't close when you click there again. (As compared tot he regular asp combobox)

Treeview node problem with Internet Explorer 7

Hi
i have a big problem with RadTreeView (version 2010.2.929.35).
The display of nodes is correct with Internet Explorer 8 and above but instead with Internet Explorer 7 when you hover the mouse over the node, the node it disappears!.
For testing i define OnClientMouseOver events:

<telerik:RadTreeView ID="RadTreeView1" runat="server" CheckBoxes="True" TriStateCheckBoxes="false"
CheckChildNodes="true" Width="170px" style="white-space:normal;" OnClientMouseOver="onMouseOver">
                            <DataBindings>
                                <telerik:RadTreeNodeBinding Expanded="False" />
                            </DataBindings>
                    </telerik:RadTreeView>
and

function onMouseOver(sender, e)
{
        var node = e.get_node();
        node.onmouseover = null;
}

the result is that in Internet Explorer 8 and above the hover is properly disabled but in Internet Explorer 7, the node continues to disappear.
Can someone help me? Thank you very much.
Marco

iPad scrolling

I'm in the process of making my web application compatible with iPad (Safari).
The problem is a RadPane, with Scrolling set to both, but also a ContentUrl set, will not scroll on an iPad.
In cases were no CententUrl is set, scrolling works fine.
Also scrolling (with ContentUrl is set) works fine on PC browsers.
Is there a solution or workaround for this?
