Hi folks,

I recieve a time duration data in seconds, lets say 90, and I need to show it as 1:30

I can just use TimeSpan.FromSeconds(90).ToString() to get this done for me, but I don't know where I can put it on RadGrid.

I only see a FormatString property, and I need to provide a little logic. Any suggestions?

Thanks,

Grid

Clicking on custom button with RadWindow maximizes the window

I am having an issue with a custom "help" button that I added to the Radwindow. When I click on my custom button, the window maximizes. And when I click on the custom button again, nothing happens. I am NOT expecting the window size to change. Does anyone know what is going on?

Telerik.Web.UI V: 2009.2.701.20
Using IE8 in Browser mode: IE8 Document mode: IE 8 Standards

Is there some embedded event that I need to cancel?

function showRadWindow() {

window.radopen("SamplePage.aspx", "sampleWindow");

return false;

}

function AddHelpIcon(radWindow) {

var radWindowDom = document.getElementById(radWindow.get_id());

var TitleBar = radWindow.GetTitlebar();

var parent = TitleBar.parentNode;

var oUL = parent.getElementsByTagName('UL');

var oLI = oUL[0].getElementsByTagName('LI'); //Get the unordered list html element

if (oLI[0].id != "HelpListItem") { //If first (list item) does not have the id of "HelpListItem"

var newLI = oLI[0].cloneNode(true);

var newA = newLI.getElementsByTagName('a'); //html anchor

oUL[0].style.width = "93px"; //width of titlebar

newA[0].className = "helpbutton"; //class inside .css file

newA[0].title = "Help Button";

newA[0].lastChild.innerHTML = "Help Button";

newA[0].onmousedown = callHelpFunction;

if (radWindowDom.attributes["HelpId"] != null) {

newA[0].setAttribute("helpId", radWindowDom.attributes["HelpId"].value);

}

oUL[0].insertBefore(newLI, oLI[0]);

oLI[0].id = "HelpListItem"; //Name the first (list item) ID to "HelpListItem"

}

function callHelpFunction(e) {

//Do something

//Cancel event!

if (!e) e = window.event;

return $telerik.cancelRawEvent(e);

}

Handling the Expired Filter

I am working on a specific requirement in Rad grid. Encounter an issue while deleting all the data corresponding to a current filter and reloads the page with the filter expression still in the combo box.

I was hoping to tackle this situation by setting the Current filter value to "All" but not successful.

RadGrid1.MasterTableView.GetColumn("Name").CurrentFilterValue = "All";

But still RadGrid1.MasterTableView.FilterExpression contains the expression for the deleted data. In prevsious version for 3.5 I could handle this situation by replacing the filter expression by string manipulation and setting the filter expression to the radgrid once again. But in the upgraded version targeting .netframework 4.0, this is not possible as the filter expression is different from that of .net 3.5 version and difficult to replace the expired value.

Is there a way to handle the filter expression for data deleted from the database, but the expression still remains in the combo box. I have a number of filter expressions but would like to avoid only those filters which don't have data exists in the database.

Reduce the width of the appointment in the day view

Hi Team,

I need to reduce the width of the appointment in the day view.
If the there is only one appointment in the specific day means, the width was too high(as shown in the figure below), but when there is two or three appointment, it fixes in the day-view precisely.
Like that, i need to control the width of the appointment in the day-view while i'm having single appointment on the particular day.
I've attached the image.

Thanks,
Daniel.B

Building multiple radgrids - index out of range

Hi there

I have a page with a radcombobox and a placeholder. When a new value is selected from the radcombobox a stored procedure runs which returns multiple result sets based on the selected value. For each one of the result sets which contains at least one row, I need to build a dynamic radgrid. The first set of radgrids always display fine, but sometimes when I select a new value I get an "index was out of range error". I've read some articles that say I need to create dynamic radgrids in OnInit, but I can't get the radcombobox selectedindex in there (at least I can't seem to - maybe someone might have an idea on this). Hopefully someone will have come across this issue and be able to assist me.

Thanks

Here's my aspx code:

<telerik:RadComboBox ID="LabsDDL" runat="server" AutoPostBack="True" DataSourceID="dsLabs"

DataTextField="Name" DataValueField="DataSourceID" Width="250px" Height="150px"

Skin="Outlook">

</telerik:RadComboBox>

</br></br>

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>

</ContentTemplate>
