I'm not exactly sure if this is a Rad control issue or not, but i'm thinking it is because the error started occurring after I added a rad grid to the program.  I have a web page that has several controls in it, including an ajax manager/loading panel.  the user adds an item number and when the add button is clicked, the manager is activated and it adds the item number to a grid (asp:GridView).  Everything works fine with that.  I just added a RadGrid and when a submit button (not the add button) is clicked, it sends out a url, which brings back info and enters that info into the rad grid. This is working just fine when using most internet browsers.  When I use Firefox with this, it's erroring out, almost like it's not even reaching my code.  here's the page i get:

Server Error in '/' Application.

Hello,

.Net 3.5Sp1

Win2003 server

IE 7 and 8

Telerik RadControls 2010.1.45  (2010 NET35)

preferred programming language C#

Receiving the error: "Insert Item is available only when grid is in insert mode."  Shown at the end of this post.  I have a grid with 3 text boxes and 3 dropdown lists.  When I click a link " Add new item" it calls the RadGrid1_InsertCommand which would add a blank record to my data source and then I rebind.  I do not modify any of the controls directly just the data source and rebind.  Suddenly I have started to recieve this error and I don't understand what has changed for me to start getting this error. I've had this working fine.  Please provide any insight you may have.

Hi...I am trying to have a tooltip display whenever I hover over the items of a radCombo.
I have done some of the work so far using an Item template, but I only know how to show either the DataTextField or dataValueField , yet the tooltip I want to show is a different field that I pull from the same table as per my query below. I want to show the suburb as my tooltip on hover.
Below is the SQL Query and binding to radcombo:
string AreasQuery = "select AreaID as AreaID,AreaName as AreaName,Suburbs as Suburbs from area order by AreaName ";
dtAreas = dbo.sqldb_select(AreasQuery, 1);
cmbAreas.DataTextField = "AreaName";
cmbAreas.DataValueField = "AreaID";

AreaID is my datavalueField and AreaName is my DataTextField.
Below is my aspx code , and I have also attached a screen shot of how this currently looks at the moment. I just dont know how to bring the Suburb Field into my ItemTemplate...maybe an attribute, but I am not sure how to use that. Kindly assist.

<td align="left" class="style11" valign="middle" bgcolor="#CC3300">
  <telerik:RadComboBox ID="cmbAreas"  Runat="server" Height="150px" MarkFirstMatch="True" 
  Skin="Hay" Width="236px" DataTextField="AreaName" DataValueField="AreaID">
  <ItemTemplate> 
        <asp:Label runat="server" ID="Label1" Text='<%# Eval("AreaName")%>' ></asp:Label> 
        <telerik:RadToolTip ID="RadToolTip1" runat="server" Width="100" Height="10" TargetControlID="Label1" Position="BottomRight" Text='<%# Eval("AreaName")%>' >
        </telerik:RadToolTip> 
  </ItemTemplate> 
  </telerik:RadComboBox>

Hi,

I use stand-alone dialogs. I switched to Q3 2009 and now I get the following ASP.NET error

The ToolName property must be set!

Nothing else was changed, I only switched DLL

Please advice soonest.

Regards,
Marc

I have a page containing four ListBoxes along with several other controls. When the user resizes IE7, the all of the ListBox controls disappear. All other controls are fine - including other Telerik controls. This only occurs in IE7. Everything is fine in FF, Chrome and Safari.

Hi,

I have hierarchy grid. On load of the screen detail table does not exists for some rows in the Rad Grid but still Expand image appears. On click of it nothing will be loaded page will be refreshed and expand button wil disappers.

Expected behaviour:
On Load itself expand button should not be displayed if no detail table exists.

Why is this problem in Telerik Version

Version=2010.1.413.40

Is there any fix for my problem?

I've discovered a bug with RadEditor when copying and pasting a link, where the link's href starts with a slash. In Firefox, the pasted link is preceded by any number of ../ and part of the path removed, and in IE, the link is changed to an absolute path including the domain.

Steps to reproduce.

1. Visit: http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx
2. In the first paragraph, change the Sharepoint link's href to: /products/aspnet-ajax/sharepoint.aspx
3. Copy the paragraph
4. Paste the paragraph somewhere else in the editor
5. View the new href of the Sharepoint link in the pasted paragraph

Results

Firefox
Link href becomes: ../../../../products/aspnet-ajax/sharepoint.aspx

IE
Link href becomes: http://demos.telerik.com/products/aspnet-ajax/sharepoint.aspx

Expected result:

Link to remain as /products/aspnet-ajax/sharepoint.aspx

Regards

Matt

I have a radgrid with inline editing. All works fine and the database updates server side with each row. I have a submit button that I do not want to validate as true unless all rows in the grid have been completed (i.e. have a value in every column for every row). Is there a way to validate the grid is fully filled out via client side script?

Thanks in advance!

I'm attempting to use a .png file for the background image of a drop down in a RadMenu control. It's just a 1px x 1px black square with a small amount of transparency and repeated, but when I view in a browser, the dropdown background is a solid gray color.

Any ideas? Thanks!

div.RadMenu_main_nav .rmItem .rmGroup {
    background-image:url('img/nav_hover_bgd.png');
    background-repeat:repeat;
    border: 1px solid #FFF;
}

Hi,

What would be the server side equivalent for set_currentPageIndex() if there is any ?

Something like :



Thank You
