Hello,

Is there a way to select the GridHyperLinkColumn row via the designer when clicking the particular link in the designer for the grid?  If not, how would I accomplish this task via server-side code?

I have attached the designer code for my grid.

Thanks,

Hi,

I'm using RadScheduler in Month view, but when creating a new appointment, I'd like the "All Day" checkbox to default to unchecked.

How can I do this?

Thanks,

I have a RadGrid whose skeleton is defined in the aspx page but the columns are defined at runtime.



The columns are added when the user hits filter button, which shows only the columns that the user wants to see.



Now when I change the value in PageSize textbox in the pager section and click the button, the page size does not change. However, if I define the columns manually in the design page itself and not dynamically then it works fine.

So I added a OnPageSizeChanged event but it doesn't get fired. I haven't tried this with undynamic columns.

Thanks.

OnRowDblClick doesnt fire Radgrid in Edit Mode.
I read a lot of post but i didnt found the solution.

I attach image of grid!

I use master/details

I need fix this urgent!

Thanks

Are the <asp:hidden> fields I have assigned to asp.net form inaccessible when I load that window as a child window with RadWindowManager?

When loaded on its own, my form can access the hidden fields using the getElementById() method.  However, when the form is launched as a Popup window with RadWindowsManager null is returned when the same script is executed.  Is this an ASP.Net issue, or do I need to do something differently clientside, such as obtain the RadWindow first via the API.  Thanks in advance.

Hi Telerik,

Could I please have an example where the 'OnFocus' and 'OnBlur' events are successfully called after being applied to a RadListBox? I've tried numerous different approaches and none of them seem to work.

Sean

EDIT: Had to set the TabIndex property per HTML5 documentation -- http://www.w3.org/TR/html5/editing.html#attr-tabindex

EDIT2: Okay, so after playing around with this for a bit, I'm still not quite where I would like to be. I would like to attach a blur event to a dynamically created RadListBoxItem.


doesn't fire anything. What's the proper procedure?

EDIT3: So I've got something that works (mostly) but I'm not happy with... I can already think of one scenario it won't work in, in fact, but I figured I'd update.

So, the RadListBox's OnClientSelectedIndexChanged event seemed like a good place to start. I came to the conclusion that there's proooobably not a good way to set the focus to a RadListBoxItem. So, I've got this:


which will set focus to the radListBox responsible for the OnClientSelectedIndexChanged event. Unfortunately, this isn't quite sufficient for my purposes.

My goal is this:

I have a button on the page which has two states: 'Edit Text' or 'Add Item'. When a RadListBoxItem is focused I want the button to say 'Edit Text'. When the user clicks away from that item I want it to say 'Add Item.' The above code will work for some scenarios, but consider the following:

• User has a RadListBox with room for 4 RadListBoxItems to be displayed.
• The RadListBox contains only 2 RadListBoxItems.
• The user selects the first RadListBoxItem. OnSelectedIndexChanged fires, and the jquery sets the RadListBox to focused.
• The user then clicks on a blank area of the RadListBox. Since the object is focused -- this doesn't change anything, but it 'feels' like to the user like they've clicked away from the item. Hence, the button should say 'Add Item'.

I have no idea really what I did to cause this. The popup RadWindow has strange visual glitches in the title bar area. I just wanted to make a basic, normal RadWindow as a popup from clicking a button in the parent page.

Here's the code for the popup window BatchAccounts.aspx:

I get this error when I try to filter on the first column in my grid:

is neither a DataColumn nor a DataRelation for table DefaultView.

<telerik:GridTemplateColumn HeaderStyle-HorizontalAlign="Center" HeaderText="PO #" Visible="true">

 <ItemTemplate>

<asp:Label ID="lblPONumber" Text='<%# Eval("_PONumber") %>' runat="server">
</asp:Label>
</ItemTemplate>

<HeaderStyle HorizontalAlign="Center" />

</telerik:GridTemplateColumn>

I am not sure what to give you so I am giving you the ASPX for the first column. 
Any ideas on why this error is occurring?

Thanks,
Chuck
