[Solved] Client-Side column value in context-menu

Hello All:
I have a context-menu on a grid. I have a non data-key (the 'lblStatus'), that I would like to cancel or continue the context menu. So during the standard 'RowContextMenu' javascript function, I need to a reference to 'lblStatus'. I believe that the following gets the data grid row.

    
            var dataItem = Sender.get_masterTableView().get_dataItems()[index];

How do i obtain a reference to the status value?
Thanks.
Phil

[Solved] AutoResizeHeight and hidden editors

I have a rad tab and in each tab has some radeditors inside. I've set each radeditor to be autoresizeheight = true.

When I go to print the webpage, I have it set with css so that all the tabs print (set div's to display). However say I don't select a tab before I print, the tabs that I don't select will print the editors with scrollbars. The tabs that I have chosen will print with their heights set properly.

Is there anything I can do to force the autoresizeheight to run even if the editors are hidden?

Thanks

Button click event not fired for a GridGroupHeader Item

Hi,

After a very long struggle, I managed to get buttons on my grid group headers. (Still there is an issue with it, like a postback making the controls to vanish - Anyway, I'll look into it later) As of now, I've added buttons to the group header items and also I have defined an event-handler for the button click event.

Please see my code below for the radgrid_ItemDataBound event

if

(e.Item is GridGroupHeaderItem)

{

Button

btnModifyStrategy = new Button();

btnModifyStrategy.Text =

"Modify Strategy";

btnModifyStrategy.CssClass =

"tab4-sub1btn";

//btnModifyStrategy.UseSubmitBehavior = false;

btnModifyStrategy.Click +=

new EventHandler(btnModifyStrategy_Click);

groupheader.DataCell.Controls.Add(btnModifyStrategy);

}

The button is added to the group header now. But when I click on the button, the button click event is not fired. Its driving me too crazy as I've been into this problem since this morning.

Can you advise me on this?

Thanks in advance.

Problem with Button in CommandItemTemplate

I have a RadGrid on my page, with a button in the CommandItemTemplate. I want to execute a client function to determine if I need to postback to do some work to do something else on the client side. When I do this, the button no longer causes a postback. It will not postback even if I simplet do OnClientClick="return true;". Is there a way to work around this. Here is some sample code.

ASPX

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="GridTest._Default" %>

[Solved] How can I attach InsertSymbol event on RadToolBarButton

Hi

I just replicate some of the editor built-in functions to my top toolbar, most of them works fine. e.g. Bold, HR, but I cannot make "InsertSymbol","InsertTable", "StripAll" work. If I use "editor.fire("StripAll")" I will receive "undefine xxxxxxx" error.

Send form with werbservice?

I have a button on a page and an xmlhttppanel that encloses an asp:Literal. Users click the button and a webservice is invoked that returns 3 comboboxes and another button into the Literal.

My intention is that the users may select items in the comboboxes, click the button, the webservice is invoked again and I am able to inspect any of the controls within the form of the page within the webservice. I want to repeat this several times, each time returning a different combination of comboboxes, radiobuttons and other html elements.

My motivation is I do not want to post the entire page back, I want to update the Literal only. Because my html will change each time, its difficult to write a single javascript function to collect all values of html controls on the page and submit them to the web service.

Is there a way to access the page form from the webservice using xmlhttppanel? If not, is there a better approach?

Set row height of grid on server side after databind

I have two grids which have the same amount of rows, but the heights of the rows are not the same. Is it possible to loop through both tables and set the row height in each table to the same amount? The first table is going to have a dynamic row height, and I would like the second table to have the same row heights as the first table. Is this possible?

Thanks!
