Control of GridTemplateColumn on PostBack

Hello,

I have an issue accessing the control of a, code behind generated, GridTemplateColumn from a click event of a button outside of the RadGrid.

<telerik:RadGrid ID="MyGrid" runat="server" AutoGenerateColumns="true" AllowSorting="true" AllowAutomaticDeletes="false" AllowAutomaticInserts="false" AllowAutomaticUpdates="false" OnColumnCreated="Siblings_ColumnCreated">

<GroupingSettings CaseSensitive="false" />

<HeaderStyle HorizontalAlign="Center" BorderWidth="1" />

<ClientSettings AllowColumnsReorder="false">

<Selecting AllowRowSelect="false" />

</ClientSettings>

<MasterTableView AllowPaging="false" DataKeyNames="MyField" CommandItemDisplay="None" TableLayout="Fixed">

</MasterTableView>

</telerik:RadGrid>

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

if (MyCondition)

{

MyGrid.MasterTableView.EditMode = GridEditMode.Batch;

var MyTemplateColumn = new GridTemplateColumn();

MyTemplateColumn.UniqueName = "MyTemplateColumn";

MyTemplateColumn.HeaderText = "MyTemplateColumn";

MyTemplateColumn.ItemTemplate = new MyTemplate();

MyGrid.Columns.Add(MyTemplateColumn);

}

MyGrid.DataSource = MyDataTable;

MyGrid.DataBind();

}

public partial class MyTemplate : ITemplate

{

public void InstantiateIn(Control container)

{

var cb = new RadComboBox();

cb.ID = "MyComboBox";

cb.AutoPostBack = false;

container.Controls.Add(cb);

}

protected void MyButton_Click(object sender, EventArgs e)

{

foreach (GridDataItem item in MyGrids.Items)

{

//This works, I have access to all the autogenerated columns and their values

string MyValue = item["MyField"].Text;

//This works, I have access to the Template column

TableCell MyTemplateColumn = item["MyTemplateColumn"];

//doesn't work => Controls.Count = 0

var MyColumnCombobox = MyTemplateColumn.Controls[0] as RadComboBox;

//doesn't work

var MyRowCombobox = item.FindControl("MyTemplateColumn") as RadComboBox;

}

Anyone can help ?

Thank you.

RadAjaxLoadingPanel with RadPrompt

Hello,

I am using a RadPrompt window to accept some basic information, which I then pass back to the server for a lengthy task. I am using the __doPostBack method to post the RadPrompt results to the server. I want to invoke the RadAjaxLoadingPanel to show I am busy while the server task completes and posts the results. My code is not working - I do not see the "loading" panel. The RadPrompt works fine, passing the desired result to the server. How can I make the RadAjaxLoadingPanel appear?

I have attached an image of the ascx code. Note that RadAjaxLoadingPanel1 and RadAjaxPanel1 are defined in code behind of the parent web part and work when other controls are pressed.

Code that defines RadAjaxLoadingPanel1 and RadAjaxPanel1

01.RadAjaxLoadingPanel radAjaxLoadingPanel = new RadAjaxLoadingPanel();

02.radAjaxLoadingPanel.ID = "RadAjaxLoadingPanel1";

03.radAjaxLoadingPanel.Skin = "Windows7";

04.radAjaxLoadingPanel.MinDisplayTime = 500;

05.radAjaxLoadingPanel.Transparency = 30;

06.

07.Controls.Add(radAjaxLoadingPanel);

08.

09._radAjaxPanel = new RadAjaxPanel();

10._radAjaxPanel.ID = "RadAjaxPanel1";

11._radAjaxPanel.LoadingPanelID = "RadAjaxLoadingPanel1";

12.

13.// load these controls

14._docSearchUserControl = Page.LoadControl(_ascxPath) as DocSearchUserControl;

15._docSearchUserControl.ID = "DocSearchUserControl";

16._docSearchUserControl.ParentWebPart = this; // add reference to this web part

JS code that calls RadPrompt and tries to show the RadAjaxLoadingPanel1 over RadAjaxPanel2 (see the attached image to see how RadAjaxPanel2 is defined)

function ExportFilesRadButton_Clicked(sender, args) {

//debugger;

var path = document.getElementById(sender.get_id()).getAttribute("Path"); // Path is set on server

if (path) {

OpenFileExportPrompt(path);

}

function OpenFileExportPrompt(path) {

radprompt('Server Path:', FileExportPromptCallBackFn, 330, 100, null, 'Server Target Location', path);

}

function FileExportPromptCallBackFn(arg) {

// alert ("Prompt returned the following result: " + arg);

//debugger;

if (arg != null) {

currentLoadingPanel = $telerik.$("[id$='RadAjaxLoadingPanel1']").get(0).control; // to avoid 'not found' error

currentUpdatedControl = $find("<%= RadAjaxPanel2.ClientID %>");

if (currentLoadingPanel && currentUpdatedControl) {

//alert("controls found");

//show the loading panel over the updated control

currentLoadingPanel.show(currentUpdatedControl);

}

__doPostBack("FileExportPrompt", arg);

}

</script>

</telerik:RadCodeBlock>

Problem with RadFormDecorator - Multiple selection in ASP ListBox

Hi,
I noticed a strange problem with ASP ListBox when RadFormDecorator is included in page. The multiple selection mode for ASP ListBox works fine when there is no RadFormDecorator in page. But when I included RadFormDecorator in page the ASP ListBox selection mode turns to Single mode though I have explicitly mentioned SelectionMode as Multiple. However, RadListBox works fine in both the cases.
This is with respect to RadControls 2009 Q3 version.

Please take a look at this issue and any solution would be very helpful to me.

The sample code and output snapshot are as follows:

Is bootstrap style open animation available for RadWindow?

Hi,

I am using asp.net and using a RadWindow for a modal popup. It works fine and i have tried the various animations provided (FlyIn, Fade, Resize, Slide).

However, my management prefers the Bootstrap open animation where the modal slides in from the top center of the window. Could you please tell me how i can do this type of animation with a RadWindow?

Thank you.
