Hi,
I am created a application using Telerik:RadGrid.It performs insert, update, delete operations successfully. I have taken a checkbox and a Button in header of one column and all the rows of that column contain checkboxex. Whenever I select the checkboxed and click on the delete button it deletes the selected records from the grid. When i Select the Header checkbox , it will select all the records of the grid with in that page and by click on the delete button it deletes all the records from that page.
I want to delete all the records across the grid when ever i select the header checkbox and click the Delete button instead delete records page wise. Can anybody help me to solve this problem.
Here is my code used to delete records page wise.

I would like to have the statusbar, but it should be empty. I set VisibleStatusbar="true". On the client side I call oWnd.set_status(''); . As a result of that, I have the statusbar visible and during loading it has no information. But unfortunately, when the it's loaded, the statusbar has the url. Is there any way not to have the url information in the statusbar, but have it visible?
Thank you,
Tatiana

Hi,
I want to restrict user to select/browse only restricted files, like in html file upload control we have a property called 'Accept' which will take the parameters as file types with cama seperated.
ex: <input type="file" accept="image/jpg,image/png" name="file1" />
I want to know whether this property is availabe in Rad Upload control?
Thanks.

Hello,
I am trying to setup my Radgrid to select multiple rows. After following the demo (http://demos.telerik.com/aspnet-ajax/grid/examples/client/selecting/defaultcs.aspx), everything works great with one exception. I can not select or deselect rows using the Ctrl Key. The Shift Key works as expected.
Here is my code:
| <telerik:RadGrid ID="radgrdEvaluator" Skin="Vista" AutoGenerateColumns="False" AllowPaging="True" AllowSorting="True" AllowMultiRowSelection="True" ShowStatusBar="False" PageSize="10" GridLines="None" width="96%" HorizontalAlign="NotSet" Visible="False" runat="server"> |
| <MasterTableView DataKeyNames="EvaluatorID"> |
| <Columns> |
| <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn"></telerik:GridClientSelectColumn> |
| <telerik:GridButtonColumn ButtonType="LinkButton" DataTextField="EvaluatorID" HeaderText="EvaluatorID" CommandName="Select"></telerik:GridButtonColumn> |
| <telerik:GridBoundColumn DataField="EvaluatorStatus" HeaderText="EvaluatorStatus" DataType="System.Boolean"></telerik:GridBoundColumn> |
| </Columns> |
| </MasterTableView> |
| <ClientSettings EnableRowHoverStyle="True"> |
| <Selecting AllowRowSelect="True" /> |
| </ClientSettings> |
| <pagerstyle mode="NextPrevAndNumeric" AlwaysVisible="True" /> |
| </telerik:RadGrid> |

I'm doing customization of FileExplorer but I've got strange strings like "Common_Open," "Common_Select" in the tooltips and buttons. Since I didn't put any string like above, it's so weird where they come from. Simply, I want to make the string as just "Open" and "Select" etc.
Any idea?

Hi,
I have a form which contains textbox and radio button controls in which some textboxes are mandatory. I have a radio button and textbox where the textbox will be enabled when I click on the radio button. The textbox should be a mandatory field only when the textbox is enabled. When the textbox is disabled/read only, it should not be considered as a mandatory field.
But, in my scenario it is considering the disabled/readonly textbox also as mandatory field. How can change this behaviour??
Thanks,
Mahesh

Hello,
I got a problem with Drag&Drop of a TreeNode. In a simple web project this false behaviour doesn't appear. But in my bigger project I have the following problem:
I got on an aspx site a simple TreeView control...
My code behind looks like this...
If i'm debugging into this event everytime the RadTreeNodeDragDropEventArgs are empty, that means, the e.SourceDragNode and the e.DestDragNode are nothing!
Does anybody has a solution for me or an idee how this can be?!
Thanks for help!!!
Best regards from Germany,

How do I handle licensing of RADControls-Ajax on our build server? Since licensing is per-seat, does the build server need a license?

I would like to use the tabstrip so that each tab points to a page. I don't want the control to navigate to the page, I want the page I reference to be the content of the tab. Is this possible?
I tried using the MultiPage example, but if you specify different URL's for each tab, the control just redirects you to the referenced page.
