Hello everyone

I have a Telerik RadGrid on a page that uses an asp ObjectDataSource. This is a search page, and the user selects some options from drop down lists etc and then clicks a Search button. The ObjectDataSource uses a SelectMethod to retrieve the data from the database based on the parameters. I have set a breakpoint here and the ObjectDataSource returns the correct dataset. However the grid does not update. I have set AllowPaging = true, and if I change the page size, the grid updates with the correct data.

Many thanks for your help

Grid

<telerik:RadGrid ID="alarms" runat="server" CssClass="gridview" AllowAutomaticUpdates="true"

AutoGenerateColumns="false" OnItemDataBound="AlarmDataBound" AllowPaging="true" AllowSorting="true"

AllowMultiRowSelection="true" PagerStyle-Mode="NextPrevAndNumeric" PagerStyle-AlwaysVisible="true">

<MasterTableView>

<Columns>

<Columns removed>

</Columns>

</MasterTableView>

<ClientSettings EnableRowHoverStyle="true">

<Selecting AllowRowSelect="True" />

</ClientSettings>

<SelectedItemStyle CssClass="selected" />

<AlternatingItemStyle CssClass="even" />

</telerik:RadGrid>

DataSource

<asp:ObjectDataSource ID="alarmData" runat="server"

SelectMethod="GetAlarmData" TypeName="******.AlarmManagement" >

</asp:ObjectDataSource>

DataSource SelectMethod

public DataSet GetAlarmData(string dummy)

{

using (SqlConnection connection = new SqlConnection(connString.ConnectionString))

{

try

{

connection.Open();

SqlDataAdapter da = new SqlDataAdapter();

DataSet ds = new DataSet();

// Get the data based on search criteria

da.Fill(ds);

return ds;

}

catch (SqlException ex)

{

// Log the error

return null;

}

finally

{

connection.Close();

}

RadCompression TroubleShoot

Hi,

I have radscriptmanager + radcompression combining and zipping up resources tremendously well on my dev environment.

Yet despite painstakingly checking web.config / code, only the combine (not compression) works on my test server.

Obviously something is amiss, but do you have any ideas (IIS 7 settings?) what could be stopping this as sure code is synced and struggling to see where to look.

Thanks
Matt

var viewPort = $telerik.getViewPortSize();

var xPos = Math.round((viewPort.width - parseInt(dock.get_width())) / 2);

var yPos = Math.round((viewPort.height - parseInt(dock.get_height())) / 2);

$telerik.setLocation(dock.get_element(), { x: xPos, y: yPos });

dock.set_closed(

false);

//var descriptionTextBox = $get('<%= ComboFacility.ClientID %>');

Sys.Application.remove_load(openFormReserve);

dotted lines disappearing in RadWindow

I've made a UserControl containing a RadTreeView; when it is embeded in a webform it works perfectly. But when I embed my userControl in a RadWindow the dotted lines that appear when you drag'n drop nodes disappear (when

EnableDragAndDropBetweenNodes=true)

!
Do you have an idea of what could cause that problem?

Saving

Is there a way to automatically save the file when the save command is clicked without showing the dialog? Possibly the best thing would be for me to override the behaviour of some of the commands. Is this possible?

On a side note: I get a javascript error when I start typing in the crop width or height dialog. I was trying to type 100. I selected the current value in the height textbox, type the 1, and it gets the error.

GridTableView events?

Hi, I have a RadGrid with a nested GridTableView. I am trying to hook up the OnPreRender event, but it doesn't ever seem to get called. After further experimentation, none of the events seem to be called on this object. The grid exhibits the same behaviour when removed from the AjaxManager. Do I need to do something else to hook up these events?

Thanks

Change group value coming from database

Hi, I want to know if when using grouping if it is possible to change the group for an item. I have an item that has Group A in the database, but in the vb code-behind I need to change the item to Group B so it gets reported under Group B. I have tried changing the GridItem("MyGroup").Text in the ItemDataBound event, but the item doesn't appear under the correct group (even though the text has been changed.

Thanks.
