couldn't find a more appropriate forum category...
button click seems to drop out when you add a dynically create button to a dynmically created pageview.
works ok if you add a dynamic button to an existing pageview.
is this an issue or am i doing it wrong?
code snippets follow...
thanks,
paul
p.s. if i add the button dynamically to the specific pageview "PV1" then the click works
protected void Page_Load(object sender, EventArgs e)
{
if (Session["counter"] != null)
{ counter = (int)Session["counter"]; }
Telerik.Web.UI.RadPageView newPageView = new Telerik.Web.UI.RadPageView();
newPageView.ID = "pv_" + counter.ToString();
newPageView.Visible = true;
MP1.PageViews.Add(newPageView);
MP1.SelectedIndex = MP1.FindPageViewByID(newPageView.ID).Index;
Telerik.Web.UI.RadTab newTab = new Telerik.Web.UI.RadTab();

Hi guys,
Can I use radajaxmanager and loadingpanel together?
I believe, if I use those controls in aspx, then it will work fine (like the below)
But what about if I have radajaxmanager in master page, and loadingpanel in the content page.
And the way I use the radajaxmanager in content page is by registering my controls into the master page's radajaxmanager.
Please advice
AGT

Hi All,
I am trying to open a Radwindow using Javascript. It works fine in IE and firefox but not SAFARI.
My function is :
Function ShowRadWindow()
{
var oWin = $find('radwndHandoverNote');
}
I get the error TypeError : Result of expression '$find' [undefined] is not a function.
Regards,
Sharanya

I have a Save button on my form in the bottom center of my page. I have a treeview on the left.
When I click on my Save button, I will perform some validation with some other items on the screen. If the validation passes, I would like the treeview on the left to set the color on the present node to red and then to move down to the next node in the tree.
Question is, how do I get a reference to the treeview and those nodes from clicking my Save button in order to perform those functions?
Thanks,
Bill

Hello:
I am trying to get a grid to show as a listview using your demo http://demos.telerik.com/aspnet-ajax/grid/examples/programming/listview/defaultcs.aspx.
The only way I can get anything to display on the screen is to comment out the lines showing in the following prerender statement.
The data that shows up is all over the place, not in a nice tabular form. Some will be in the grid, some appear to be outside etc.
If I uncomment the lines of code in the prerender I get nothing to display in the grid at all. It will iterate through the grid.items etc. as it should but nothing will display. I have verified that the data is in the datasource when bound.
My Radgrid code is below
Thanks for your time.

Trying to add a bit of visual eye candy to my RadComboBox...
I am pre-populating a RadComboBox with values from a database. While doing this, I'm adding an item at the top called "Select an Analyst" which gets used if the value is null. I'm adding this item in italics...kind of how it looks when use EmptyMessage. What I would like to do though, is if someone selects an item in the RadComboBox that is not "Select an Analyst", the font changes back to normal.
I'm assuming I would have to do this with client side javascript, but I can't seem to figure out client side how to change the font property of the RadComboBox. I'm using the OnClientSelectedIndexChanged event. Can I change the font style based on the eventArgs client side?
Thanks for the help!

Mostly out of curiosity, I am wondering if anyone actually uses the Autogenerated Columns feature? There are several reasons I never use it (mainly that I want more control over how it looks) but the biggest reason of them all is that the names the columns have in the database almost never are what you want the user to see. Considering that this option is almost at the top of the Smart-tag in Visual Studio, at least Telerik must think that a lot of people use this, so I cant help wondering, "is there a smart way of using autogenerated columns that I just dont know about??"
