How to get values programmatically from RadWindow?

Hi,

I am working RadWindow control. I want to get values from RadWindow and use these in parent window (web page) using C#.Net (code behind).

I have already saw/read some demo but i am not getting because most them are not based on code behind those examples are using aspx.

for example: http://demos.telerik.com/aspnet-ajax/window/examples/clientsideevents/defaultcs.aspx?product=window

I want these type of code in code behind file like C#.Net.

Please guide me.

Thanks

How get my old status after refresh

Hello,
I use a TreeView with Checkboxes. I refresh my TreeView every 30 seconds with a timer. This works very well. Unfortunately, when i have selected any Items after the refresh my Selecting is lost. Is it possible, that i get my old Selection after the Refresh?

I use a ObjectDataSource (ODSLoadPlayerFromScheduler) for my TreeView.

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

LoadDB();

}

else if (IsPostBack)

{

LoadDBAfterPostback();

}

private void LoadDB()

{

int projectGroupID = pgID;

if (!parameter.ToLower().Contains("administrators"))

{

ODSLoadPlayerFromScheduler.SelectParameters.Add("GroupName", parameter);

ODSLoadPlayerFromScheduler.SelectParameters.Add("projectGroupID", projectGroupID.ToString());

}

else

{

ODSLoadPlayerFromScheduler.SelectParameters.Add("projectGroupID", projectGroupID.ToString());

}

private void LoadDBAfterPostback()

{

int projectGroupID = pgID;

if (!parameter.ToLower().Contains("administrators"))

{

ODSLoadPlayerFromScheduler.SelectParameters["GroupName"].DefaultValue = parameter;

ODSLoadPlayerFromScheduler.SelectParameters["projectGroupID"].DefaultValue = projectGroupID.ToString();

}

else

{

ODSLoadPlayerFromScheduler.SelectParameters["projectGroupID"].DefaultValue = projectGroupID.ToString();

}

protected void Timer1_Tick(object sender, EventArgs e)

{

LoadDBAfterPostback();

}

Can you help me with the solution to my problem?

RadDateTimePicker style issue

Dears,
I am using Telerik controls (product version 2010.1.519.35)
i have a RadDateTimePicker, when i press the open calendar popup button, the calendar is transparent and very hard to see numbers.
I tried to override the default style embedded in your DLL by using my style :
.PickerCss,
.PickerCss .rcTable
{
background-color:inherit !important;
}

but your style (in DLL) is !important too and it is taking precedence over my style.
of course i cannot delete your style , so what i can do ?
Regards.

Progress Bar Not Closing

Hi,

I have added a progress bar to one of my pages to monitor when a custom process is complete. I used the code from the demo Upload/Monitoring For Custom Progess.

The progress bar opens and works great, but it doesn't close when the process is complete. After reading the other threads concerning the Progress Bar not closing, I thought the problem might be that something in the procedure I am calling was preventing the Progress Bar from closing, so I commented out that line and ran it again and the Progress Bar still doesn't close.

Did I miss something in the example or is there a way to manually close or stop the progress bar?

Thanks

Here is the aspx code

<

FilesCount,

FilesCountPercent,

SelectedFilesCount,

CurrentFileName,

TimeElapsed,

TimeEstimated"

Skin="Hay">

</telerik:RadProgressArea>

<telerik:RadProgressManager ID="RadProgressManager1"

Runat="server"

SuppressMissingHttpModuleError="True"

RefreshPeriod="100" />

Here is the code on the button click

Private

Sub ibtPDFExport_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ibtPDFExport.Click

Dim aryInvoiceNumber() As String

Dim i As Integer = 0

Dim sdrIntranetObjects As SqlDataReader

Dim strDirectorySuffix As String = Nothing

Dim strFileName As String = Nothing

If Me.txtRecordsSelectedCount.Text = "0" Then

MsgBox(

"You must select at least 1 invoice to export.", vbOKOnly)

Else

Dim Progress As RadProgressContext = RadProgressContext.Current

Progress.Speed =

"N/A"

ReDim aryInvoiceNumber(Convert.ToInt16(Me.txtRecordsSelectedCount.Text) - 1)

For i = 0 To Convert.ToInt16(Me.txtRecordsSelectedCount.Text) - 1

aryInvoiceNumber(i) = Split(

Me.txtRecordsSelected.Text, ";")(i).ToString

SqlStr =

"SELECT InvoiceNumber, PeriodEnding, Contract, Customer From [dbo].BLL_BillingInvoiceHeader WHERE InvoiceNumber = '" & aryInvoiceNumber(i).ToString & "'"

sdrIntranetObjects = UDF_GetDataReader(SqlStr)

ItemDataBound called twice for GridItemType.Header

I have
void rgtClients_ItemDataBound(object sender, GridItemEventArgs e)
{
switch (e.Item.ItemType)
{
case Telerik.Web.UI.GridItemType.Header
....
}
but what is happening the case Telerik.Web.UI.GridItemType.Header is executed twice for the same e.Item.ItemIndex)
So I have to keep track which row I am at, with if (intCurrentGridIndex != e.Item.ItemIndex)
What will cause such behavior? Should't it be iterating through rows, including header?

LoadonDemand Problem RadCombobox with RadNumericTextbox

Hi,

I am using RadNumeric Textbox inside Radcombobox and loading the products on Radcombobox using LoadonDemand. However, when I try to open the radcombobox I get the following error but this error doesn't occur if I bind my radcombobox without using loadondemand.

Is this a problem because I am using load on demand ?
