Hello everyone. I have a page with a grid in which the grid and sort works properly when used against the personal webserver that comes with Visual Studio but not when used against the remote server. When I say remote server I mean from one of the those hosting companies that you pay a small fee per month. In trying to solve this problem I even allowed reordering but it still didn't solve the problem and even with reordering turned on the project works fine off of the personal web server. Can someone please give me a hand with this?

RIght Pane not updating

hello,
I have a splitter with: left pane, splitbar and a right pane.

In the left pane i have a radio button list(which causes a postback)

In the right pane i have a radgrid(using NeedDataSource) and this should be updated depending on the radio button clicked.

And in the SelectedIndexChanged of radio button i have

RadGrid1.DataSource = Nothing

RadGrid1.Rebind()

All the sequence of steps are perfect, but the Radgrid is not getting updated. Is it because AJAX only updates the left pane ? Please help. Thanks

PS:When i click on the Page 2 of the old grid, then i can see the new updated grid.

Call context menu programatically with WatiN

Hi,

I am writing some tests in IE around our RadTreeView using WatiN. It's great for navigating the tree and expanding nodes but I am having some trouble raising our XML defined context menus via right click.

I've tried simulating a right click using

private void ContextClick(Element span)

{

NameValueCollection eventProps = new NameValueCollection();

eventProps.Add("button", "2");

span.FireEvent("onmousedown", eventProps);

}

where span is the Span DOM element that contains the relevant node name. To my mind this should simulate the user right clicking on the node. All I see happening though is that the node is highlighted yellow. Anything to do with not havign a cursor/mouse position?

I've check the client-side API and I can see a function for making the Context menu disappear but I can't find anything I can call on the page to make it appear. Is there anything like this or can anyone think of a way of simulating a right mouse click on a node using server side code?

Many thanks in advance...

How to persist the value after postback with in radgrid form template

Hello All,
i added one radgrid dynamically in asp.net application. in the radgrid i am using the form template to insert and update the record, i have three columns in the grid like Col1,Col2,Col3. all are the textbox columns. Col3 have one radimagebutton. if i click the radimagebutton it will open the radwindow and i pick some image after click ok button in the radwindow it will bind the value in Col3 textbox, this functionality is fine, but my question is

1. i entered some value in col1 and col2 textbox
2. after bind some image value in the Col3 textbox. col1 and col2 textbox values are gone because of postback
3. above scenario i handle in insert button through grid_itemCommand event, if i insert the form template all values are persist
4. but when i update that time i cannot able to persist the col1 and col2 values, col3 values are there
5. when i click the insert button in grid_itemcommand event the item will come as grideditformitem, so i can able to get the entered value using
GridEditFormItem item = (GridEditFormItem)e.Item;
string col1value=item.FindControl("Col1textboxid").Text;
and rebind to the corresponding textbox
6. when i click the update button in grid_itemcommand event the item will come as griddataitem, here i cannot find the control and cannot get the value, please tell me to persist the value

Kindly tell me how to resolve this issue

Serious problems in IE9 with 2011 Q3 and Editor in Div-mode

Hi,

When using IE9 the editor sometimes inserts html in the parent window.
Try the following in your demo (ContentAreaMode='Div'):
1. Select all text in the editor (Ctrl-A)
2. Press delete to clear all text
3. Press the "Numbered List" toolbar menu item.

When doing this, and other cases to but this was an easy way to demonstrate the problem, the "1. " text is inserted at the top of the entire page!!!
This breaks our entire application...

Regards
Caesar

The message received from the server could not parsed

Here is what I am doing:

RadGrid has a GridButtonColumn. When column hyperlink is clicked (OnItemCommand) I do among other things Response.Wirte and it blows up inside Telerik client code with famous error:

Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when ....

What is workaround for this? I believe it has to do something with making hyperlinks to do postback, right?
