RadGrid stop page from refreshing everytime

Hi

I have built a my first database using radgrid, however everytime I change pages (pressing the page numbers at the bottom) or filtering, the page refreshes everytime.

I would like it to act like the example on the following link:

http://demos.telerik.com/aspnet-ajax/grid/examples/performance/linq/defaultvb.aspx

In this example, only the records change, but the page remains the same.

Could anyone advise what settings I have to change in radgrid in order to achieve this ?

thanks in advance

Problems with RadTabStrip when adding more then one usercontrol.

When adding more than on control to the RadTabStrip, the navigation between tabs and the user controls's submit are unable.

If I have just one control everything works fine. the problem appears when adding the second user control to the RadTabStrip.

Please, any help?

__doPostBack function

Hello,
I have an ASP.NET Ajax Calendar, with AutoPostBack = false
When client change viewed month I use this event : ClientEvents-OnCalendarViewChanged="postBack"
To call this Javascript function :

function postBack(sender, args) {

__doPostBack("<%= RadCalendar1.UniqueID %>", "myArgument");

}

Here is my Page_Load function :

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

RadCalendar1.SelectedDate = DateTime.Today;

}

else

{

string eventTarget = (this.Request["__EVENTTARGET"] == null ? string.Empty : this.Request["__EVENTTARGET"]);

string eventArgument = (this.Request["__EVENTARGUMENT"] == null ? string.Empty : this.Request["__EVENTARGUMENT"]);

if (eventArgument.Equals("myArgument"))

{

RadCalendar1.SelectedDate = DateTime.Today.AddDays(-10);

 // Just for test

}

FillHolidayDataset(RadCalendar1.SelectedDate);

}

The problem is when I change month, I Have this error :

Invalid navigation argument: [myArgument]

[ApplicationException: Invalid navigation argument: [myArgument]]
   Telerik.Web.UI.RadCalendar.RaisePostBackEvent(String eventArgument) +864
   Telerik.Web.UI.RadCalendar.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +13
   System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13
   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +176
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +5563

What's wrong with my doPostBack function ?

Regards
Cemka

RadToolTip with RadRotator content does not display RadRotator

When using a RadRotator inside of a RadToolTip the RadRotator does not display. Is there something I can do to get around this?

See this example for more information:

Delete OnClientItemDoubleClicked

I need a little help executing a SQL Stored Procedure from the Code Behind using OnClientItemDoubleClicked.

Here is my ASPX code for the list box:

<telerik:RadListBox ID="rlb_JobRoles" runat="server"

DataKeyField="RoleName"

DataSortField="RoleName" DataTextField="RoleName"

DataValueField="RoleName" Width="245px" OnClientItemDoubleClicked="RemoveJobRole">

</telerik:RadListBox>

And my code behind:

Protected Sub RemoveJobRole(sender As Object, e As System.EventArgs) Handles rlb_JobRoles.SelectedIndexChanged

Dim DatabaseName As String = rcb_Database.SelectedValue

Dim MemberName As String = Session("UserInRoleName")

Dim connectionString = New SqlConnection("server=DO-IT-AB\MSSQLAB;database=AeriesAdmin;UID=itc.sysadmin;PWD=m1s.@dm1n6;")

Dim command = New SqlCommand("aa_user_drop_role", connectionString)

command.CommandType = CommandType.StoredProcedure

command.Parameters.Add("@dbname", SqlDbType.VarChar).Value = DatabaseName + "."

command.Parameters.Add("@name_in_db", SqlDbType.VarChar).Value = MemberName

command.Connection.Open()

command.ExecuteScalar()

command.Connection.Close()

End Sub

I receive the following error when I open the page:

Error: 'RemoveJobRole' is undefined

Any help much appreciated.

RadAsyncUpload manual hide/show javascript

Hello, I'm trying to make manual handle when to show/hide inputs for radasyncupload.




var filesUploaded = 1;
var maxFileCount = 2;
  
function FileSelected(sender, args) {
    filesUploaded++;
      
    if (maxFileCount == filesUploaded)
         $(".ruInputs > li:last").remove();         
}
  
function FileUploadRemoved(sender, args) {
    if (maxFileCount == filesUploaded)
        sender.addFileInput();
  
    filesUploaded--;          
}

Following code works quite well if fileUploaded is initialy 0. But once I need to set it to 1 on the beginning. 



Scenario is following:

Add file. - input disapears. - correct

remove file - two inputs is showing. 



I would like to prevent such scenario. 

I don't have MaxFileInputsCount set to control - I don't like the way how it is handling file. And it causing me other problems.



And more thing. I don't know whay but e.g. in firefox 4b11. After some adds and removes clicking on control not working. Looks like silverlight not support clicking any more. (Silverlight is loading by default). The version I have is 2010.3.1317.40. Ican click multiple times and sometimes it is working sometimes not.
