Redirecting Parent From RadWindow Code Behind Issue

I am having a hell of a time getting this to work correctly. I have a RadWindow that can be launched from any site on the page (the link resides on a master page) and will bring up a login window.

When the user successfully logins in, the SQL reader will set a variable in session and then once the data reader has closed SHOULD redirect to a page based on what is stored in the session variable.

So I need to be able in my code behind to say If Session("ThisValue") = Something then Close RadWindow and redirect parent.

I have this code in the RadWindow:

<script type="text/javascript">

function RedirectUser(sender, args) {

GetRadWindow().BrowserWindow.location.href = '../ThisPageWhenRedirectUser.aspx';

GetRadWindow().close(); //closes the window

}

function GetRadWindow() //Get reference to window

{

var oWindow = null;

if (window.radWindow)

oWindow = window.radWindow;

else if (window.frameElement.radWindow)

oWindow = window.frameElement.radWindow;

return oWindow;

}

</script>

I just don't know how to call that from my code behind. I am trying it like so:

'after database has retrieved and stored the value in session

If (Session("UserType") = Something Then CloseRadAndRedirect()

Public Sub CloseRadAndRedirect()

If (Not ClientScript.IsStartupScriptRegistered("GetRadWindow")) Then

ScriptManager.RegisterStartupScript(Page, Me.GetType(), "GetRadWindow", "RedirectUser();", True)

End If

End Sub

This does not work. In fact it simply refreshes the radwindow and the controls lose their formatting and styles.

Any help would be greatly appreciated.

We are using RadCalender in our application.
By default RadCalender displaying current month.
Our requirment is differ to this.

in our code we are having a variable selectDate(this variable contains date).

HI,

I need to add a RequiredFieldValidator to the grid. The columns are autogenerated.
I was able to acess the column value in the InsertCommand untill I added the below code to the ItemDataBound.

TableCell cell = (TableCell)editor.TextBoxControl.Parent;

RequiredFieldValidator validator = new RequiredFieldValidator();

editor.TextBoxControl.ID = "txtValue";

validator.ControlToValidate = editor.TextBoxControl.ID;

validator.ErrorMessage = "*";

cell.Controls.Add(validator);

}

Problem after any ajax call

hello,
i'm developing a web application that contains tabstrip control , multipage pageview controls,i have a button and through this button i want to navigate through tabs using ajax everything was working ok until i've added the prometheus editor in my page the following error was raised
The PageRequestManager cannot be initialized more than once."
this error is raised on "IE7" but in firefox it was running ok

Assuming assembly reference 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' matches 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35', you may need to supply runtime policy

please note that i'm using Rad ajax manager v 1.8.1.0,VS 2008 beta1

How to chech the cursion position in rad editor

Hi, i am using rad editor in wysiwyg mode.

I need to insert some text to cursor position.

before paste some text, i need to check some condition like, the given cursor position is center/left/right of the particular elememt.

My code like

var selectedtag = editor.getSelectedElement();

var range = editor.getSelection().getRange();

var selection = editor.getSelection();

if (selectedtag.tagName != "LI" && selectedtag.tagName != "P") {

var sel = editor.getSelection().getText();

var text = selectedtag.innerHTML;

//range.pasteHTML('<p>' + sel + '</p>');

selectedtag.innerHTML = '<p>' + text;

}

else if (selectedtag.tagName == "LI") {

var sel = editor.getSelection().getText();

if (sel == "") {

range.pasteHTML('</li><li>...</li>');

}

else {

range.pasteHTML('</li><li>' + sel + '</li>');

}

else if (selectedtag.tagName == "P") {

var sel = editor.getSelection().getText();

if (sel == "") {

range.pasteHTML('</p><p>');

}

else {

range.pasteHTML('</p><p>' + sel + '</p>');

}

else {

var sel = editor.getSelection().getText();

if (sel == "") {

range.pasteHTML('</p><p>');

}

else {

range.pasteHTML('</p><p>' + sel + '</p><p>');

}

i got the range.
But , how to check if the selected text has any text before and after.

I need to implement some text based on the condition like,

Te Text to the left is empty (ie selection is at the start of the element): <p> selected text text to the right</p>

3) Text to the right is empty (ie selection is at the end of the element): <p>Text to the left selected text </p>

i need the output like,

<p> selected text</p><p>text to the right</p>

How to check if the selected text /range contains any text before and after the selected text.

This is urgent requirement.
Thanks ,
Uma

Customize Spell Check Action

I am interested in using Telerik RadSpell client side. My specific need is that I want to be able to control the action performed on the replaced/corrected words. Is there a way to bind to an event that will allow me to custom wrap the corrected word in some additional HTML?

Delete a Row from RadGrid Client-Side

Hi

I am having a problem at the moment removing a row from the RadGrid client side.

Our RadGrid is built up via xml defined from a generic RadGrid declaration. On the particular page i am trying to remove a row i have the following defined (where index is the row selected):

function DeleteRow(index)
{
     var masterTable = $find('<%=RadGrid1.ClientID=>').get_masterTableView();
     masterTable.deleteItem(masterTable.get_dataItems()[index].get_element());
}

The problem is that function deletes all rows in my grid and not the index that i supplied it. I have checked the index value and can confirm that changes to the row i have clicked on. Can you provide an alternative solution?

Regards,
Jonathan

[Solved] when ReBind() is called twice, NeedDataSource is not fired the second time

Hi,

please see this example: when the DoSomething button is pressed, ReBind() is called twice. The second time, the RadGrid does not refresh.

public partial class _default : System.Web.UI.Page

{

protected override void OnInit(EventArgs e)

{

if (!IsPostBack)

{

Session["data"] = new List<string>() { "ready", "ready" };

}

base.OnInit(e);

}

protected DataTable GetGridDataTable()

{

List<string> data = Session["data"] as List<string>;

DataTable dataTable = new DataTable();

dataTable.Columns.Add("Name");

foreach (string s in data)

{

dataTable.Rows.Add(s);

}

return dataTable;

}

protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

RadGrid1.DataSource = GetGridDataTable();

}

protected void Button_Click(object sender, EventArgs e)

{

Session["data"] = new List<string>() { "loading", "loading" };

RadGrid1.Rebind();

System.Threading.Thread.Sleep(2000);

Session["data"] = new List<string>() { "finished", "finished" };

RadGrid1.Rebind();

}

<div>

<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource" Width="400px">

<MasterTableView DataKeyNames="Name" Name="ParentTable">

<Columns>

<telerik:GridBoundColumn DataField="Name" UniqueName="Name">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

<asp:Button Text="Do something" OnClick="Button_Click" runat="server"/>

</div>

</form>

</body>

</html>

Right now, after the button is pressed, the grid displays "loading", but then does not display "finished". How would I get RadGrid to correctly display "loading" and then "finished"?
Thanks,
Donald
