I am having trouble trying to do a crosspage postback when a user double clicks on a grid row. Using the example found at

http://www.telerik.com/support/kb/aspnet-ajax/grid/performing-postback-from-grid-client-events.aspx I did the following for my aspx page. I think the issue is using the ajax manager with the grid. I want the ajax manage for all the other events such as paging, sorting, etc., but not for the client double click which I want to do a full postback with a the postback url being another page.

 

Hi there

I have a grid which is bound client-side. The table contains about 10 columns of which some are fixed width and others aren't.
When I page through the grid everything works as expected until I reach the last page. Then the scrollbar disapears the headers are misaligned with the table content.
I found that calling grid.repaint() from the client when the data is bound fixes this problem for Internet Explorer 7 (haven't tried other versions), however, Firefox doesn't seem to care and the grid is misaligned until the scrollbar reapears (pushing the content back to place). The problem is a bit different in Google Chrome, but it's still an issue.

Is there any way to realign the headers programatically through script whenever a scrollbar (re)apears?

Hi,

I have a load-on-demand combo box but have a problem where you can type something in the text field and even if what is typed does not match an item in the combobox, if you tab out, or click out of the control, the page posts back, the selected index changes and what was typed remains in the combobox text field.

I would like the behaviour of the control to not post back if what someone types does not match an item, but does post back if the item matches. I presume this is a client-side event I need to handle for this, but I would appreciate some help.

Thanks
Tom

Control:

<telerik:RadComboBox ID="ddlStudents" EnableViewState="false" runat="server" EnableVirtualScrolling="true"
                      ShowMoreResultsBox="true" EnableLoadOnDemand="true" OnItemsRequested="ddlStudents_ItemsRequested"
                       OnClientDropDownOpening="OnClientDropDownOpening" AutoPostBack="true" EnableItemCaching="true" HighlightTemplatedItems="true" EmptyMessage="Select a student or start typing their name" ExpandAnimation-Duration="150"
                       MarkFirstMatch="true" EnableTextSelection="true" IsCaseSensitive="false" CollapseAnimation-Duration="9" Skin="Default" DataValueField="StudentId"
                        DataTextField="CombinedName" ToolTip="Select a student from the drop down list or start typing their name/ID to return only those students matching your criteria."
                        OnSelectedIndexChanged="ddlStudents_SelectedIndexChanged" MaxHeight="250px" Width="100%">

Hi,

I have a radEditor on a web page. Unfortunately, the way the text is saved and interpreted by another site (beyond my control), requires a css class to control each of the the bullet types. So what I have done is created a custom function every time the ordered and unordered lists are created. The problem now is, when I hit the bullet button twice, it no longer takes away the list item, it adds another list.



Is there any way to grab the line of text the cursor is on when you hit the button on the tool bar? Or is there a better way to do this (maybe like limiting the amount of list items a list can have?). When I try to use createRestorePoint() I get an undefined error, even though I'm not sure I can use it anyway. Thanks for the help.

Basically it appears that WebKit browsers like Chrome and Safari are triggering requests when they shouldn't (IE and Firefox appear unaffected).This example has a simple RadTextBox with a button which calls an onclick event for a hidden button. Clicking the textbox's button works fine, calling the onlick of the hidden button works fine, but pressing ENTER inside the textbox to issue an ajax request via the hidden button fails to show the loading panel, in fact it does show it, but it immediately hides it due to a back to back requests and responses. After the first ENTER, subsequent ENTERS cause mulitple responses that do not match the number of requests, however the textbox's button will show the loading panel despite having an incorrect number of responses? Can anyone help explain/fix this?

Here is a very simple sample: (Q2-2009 RadAjax.NET Controls)

Hi there,

Is it possible to localize this control?

Thank you.

EDIT: Never mind ... I thougt that there will be some .resx called FileExplorer. I found what I needed.

Hi,

I need to know how to make it possible to reorder the rows in a single rad data grid using grid drag and drop functionality.

I went through live examples as well as few posts in here, yet, couldn't find the solution. all what I'm looking for is to allow users to drag and drop rows to perform reordering and to show the new ordering as well.

It's highly appreciated if you can provide code sample that demonstrate the above scenario, and please don't ask me to view live examples because I already did and couldn't find the solution!

Thanks for your help and assistance in advance :-)
