Save grid to PDF and don't display dialog box

Hi,

I've got the following code that I am running server-side to export the grid and save it to PDF. I then don't want to show the Dialog box to the user so I can then do more in code to attach the saved PDF to an email.

This is the code I have to save the file:

protected void grdDailyList_GridExporting(object source, Telerik.Web.UI.GridExportingArgs e)

{

string path = Server.MapPath("~/DailyList/list.pdf");

if (File.Exists(path))

File.Delete(path);

using (FileStream fs = File.Create(path))

{

Byte[] info = System.Text.Encoding.Default.GetBytes(e.ExportOutput);

fs.Write(info, 0, info.Length);

}

How do I then prevent the dialog box from getting displayed?

Or can I move the above code to get the grids ExportOutput code without having to go through this method?

Thanks, Mark

Accessing Radgrid and Toolbar in nestedviews

Hello all,

I have a RadGrid (RadGrid1) with a nestedviewtemplate. In the template, I have a RadToolbar (RadToolBar1) and another RadGrid (RadGrid2). I have set up the data sources and the grid works fine and shows the appropriate child items in the second RadGrid.

My problem is referencing the RadToolbar and the two RadGrids clientside using javascript. When a user selects an option from the RadToolbar1, I need to get row number of RadGrid1 and a reference to RadToolbar1 and RadGrid2 which is inside the nestedviewte,plate.

I have look at many many forum articles and demos and cannot seem to get the correct clientside code. I have included my code below.

Any help would be greatly appreciated.

Thanks
Ryan

RadWindow not found on page redirect

Hello:

I have a Website that inherits a .master page. The master page contains a RadWindow and a JavaScript method to show the RadWindow:

<telerik:RadWindow ID="Window1" runat="server" Modal="True" VisibleOnPageLoad="false" EnableShadow="true"

Behaviors="Close" ReloadOnShow="true" AutoSize="false" Height="600" Width="800">

<ContentTemplate>

<asp:UpdatePanel ID="Window1UpdatePanel" runat="server" UpdateMode="Always">

<ContentTemplate>

</ContentTemplate>

</asp:UpdatePanel>

</ContentTemplate>

</telerik:RadWindow>

function OpenModalWindow() {

var oWnd = null;

oWnd = $find("<%=Window1.ClientID%>"); }

oWnd.Show();

}

One of my user controls does a response.redirect and loads a user control dynamically. The user controls Load event executes the JavaScript code from server side, which is supposed to show the window. It throws an error saying that oWnd is null (granted the JavaScript code and the modal are on the same master page). If I do a document.getElementById it returns an actual result (but tells me that .Show is an invalid method). So the object seems to exist. I know it's a shot in the dark but does anyone have any suggestions? On controls where the page is NOT redirecting it seems to work fine...thanks!

Not able to use mouse to select from combo

I am using the RadXmlHttpPanel to load a dropdown based on teh value of other dropdown. Below is my case.

I have a state comobo. when user select a value then the county dropdown should list the counties for that state. Both State and County is coming from the DB.

I have the county dropdown in the RadXmlHttpPanel.
My problem is. When the choose the state dropdown for the first time I am seeing the counties populated correctly and I am able to choose from the county list.
But then when I try to change the state then I am not able to do with the mouse. The list of state show in the dropdown but not able to choose from the list. But I am able to use the key board and select and the county dropdown populates accordingly.

Here is the code I am using.

<telerik:RadComboBox ID="cmbState" runat="server" Width="50px"

OnClientSelectedIndexChanged="ComboChanged">

</telerik:RadComboBox>

<telerik:RadXmlHttpPanel ID="CountyXmlHttpPanel" runat="server"

OnServiceRequest="CountyXmlHttpPanel_ServiceRequest" EnableClientScriptEvaluation ="true">

<telerik:RadComboBox ID="cmbCounty" runat="server"

Width="100px" DropDownWidth="250px" >

</telerik:RadComboBox>

</telerik:RadXmlHttpPanel>

function ComboChanged(sender, args) {

var foundPanel = $find("<%=CountyXmlHttpPanel.ClientID %>");

var stateCombo = $find("<%= cmbState.ClientID %>");

var stateVal = stateCombo.get_value();

foundPanel.set_value(stateVal);

}

protected void CountyXmlHttpPanel_ServiceRequest(object sender, Telerik.Web.UI.RadXmlHttpPanelEventArgs e)

{

//Bind county here

}

Thanks
