Aligning markers and labels

Hi, I've a standard line chart. It is possible to align the markers so that they are on the grid lines. And also, so that the date labels on the X-axis match up to the grid lines instead of being in between lines. Thanks.

Hi I am using a RadGrid (Telerik.Web.UI.dll version 2010.2.929.35) control with default PageSize as 5 .When the user is navigating to next page, the page size which we have selected (suppose 10)is changing back to the default one(here 5).

How we can maintain the page size selected by user in different pages?

Please help me to resolve the issue.

[Solved] Select button has no response

Hi,

I am using version 2013 Q1 on IE10. I have the following issue when using the component.

I placed the AsyncUpload in a Radgrid EditTemplate which in turn residing in a RadWindow. When I press the SELECT button in the AsyncUpload component, the file browser popup where I can select a file to upload. This works well as long as I stay in the RadWindow; however, when I exit the RadWindow (returning to the calling page) and come back again, the file browser didn't popup at all no matter how many times I click the SELECT button.

The same issue was found when I tried this on IE8 and IE9. Any idea of what might have caused this?

Thanks.
Emily

Header Context Menu - IE10

Hi,

I am having a problem with the column selection feature of the header context menu in IE10.

The menu shows the list of available columns but it is not possible to check or uncheck any of the items in the list. The underlying columns are hidden and shown but its rather an uncomfortable user experience.

It seems to work fine in Chrome, Safari, Firefox and also IE10 in compatibility mode.

If you activate the menu in your demo you can reproduce the problem.

Any ideas?
Thanks

Bob

Hello,

my problem it's like here:
http://www.telerik.com/community/forums/aspnet-ajax/grid/accessing-old-amp-new-values-in-itemupdated-iteminserted-and-itemdeleted.aspx

How can I get the old values in all input refill, if I get a exception on ItemUpdated?
I try here the code:

protected void RadGrid1_ItemUpdated(object sender, GridUpdatedEventArgs e)

{

if (e.Exception != null)

{

e.KeepInEditMode = true;

e.ExceptionHandled = true;

flag = 1;

GridEditFormItem editedItem = (GridEditFormItem)e.Item;

Hashtable new_values = new Hashtable();

Hashtable old_values = new Hashtable();

e.Item.OwnerTableView.ExtractValuesFromItem(new_values, editedItem);

old_values = (Hashtable)editedItem.SavedOldValues;

foreach (Object key in new_values.Keys)

{

string value = old_values[key].ToString(); // Here I get a error! With: Object reference not set to an instance of an object.

}

Any ideas? Im still a beginner (;
Thanks..
