Hi,

Can somebody help me with showing and hiding tabs in code behind? I've tried many methods and none seem to work. I really appreciate your assistance with this one.

Thanks,
Ron.

Is there a way to ensure that the RadGrid control height is always 100% of the datasource content?

For example, if there are only 3 rows in the grid, the height of the grid control would only be as tall as the three rows in the datasource plus the header row.  All controls on the page below the grid would be displayed directly below the grid.

If the datasource of the grid changed so that the results contained 15 rows, the height of the grid would change to show all 15 rows, and again, any controls on the page below the grid would show directly below the results.

Thanks.

I find an issue in Radgrid.  I couldnt fix it.   I create some columns programmatically.  When I hide colum from header context menu, some blank colum is appear al last.  Copy aspx, aspx.cs and Image (before and after hide column)...  ASPX:                                            <%@ Page Title="" Language="C#" MasterPageFile="~/UI/Doculex.Master" AutoEventWireup="true" CodeBehind="DocumentsList.aspx.cs" Inherits="WebSearch.UI.DocumentsList" %>

i have a problem with the OnNodeClick event in the tree view. I have the following code in ascx file :


And i am adding the nodes in the code behind:

My code behind:

 
On Init i am just loading one root node guest, and when Expand is clicked, i am populating
1 to 10 as child nodes. Now, when i click on one of the nodes, i can hit the break point  at RadTreeView1_NodeClick and when i run, the tree is getting populated and
everything is fine. Now, my problem is, when i click another node, i CANT hit
the break point(on the second node click) and the tress is also not getting
populated. I can just see "Guest" and not the below nodes. Can any one
please help me. Thanks

Hello,

I'm doing a programmatic insert with a radgrid, and graving the newvalues out of the insertitem. I am doing this in a procedure handling then InsertCommand event. The insert itself works just fine...

The trouble is that I can't figure out how to close the insert form. I can rebind the grid, but that doesn't do it, I have tried IsItemInserted = false, but that throws an error. How on earth do you get the grid to just close and rebind normally when doing a programmatic insert?

Thanks,

Mike

hello this is my i want when i click on in retrun my grid's row id in code thanks

Hi,

This is an Internet Explorer only related issue, it doesn't happen in Firefox, and as such I don't know how to trouble-shoot it.

I have a MasterTable that contains a bunch of columns, a few of which have specific widths set. The columns are created dynamically using AutoGeneratedColumns, and the widths are set in the ColumnCreated procedure.

This MasterTable has two DetailTables, and I currently have two entries. The first one has only short amounts of data in it, and as such no column ever has more than one line of text in it. This one works absolutely fine, I can expand and collapse the DetailTables without any problems at all.

The second one has a Note that is about 500 characters long (the note in the previous one is 10 characters long). When I expand THIS detail table the MasterTableView loses all it's widths for the columns and they all become completely random widths, seemingly dependent on the content and not on the actual defined sizes. When I collapse it they return to normal.

While this isn't the biggest problem in the world it is incredibly annoying from a design point of view because I don't want the columns to randomly resize whenever one of the DetailTables happens to contain a stupidly long value that's too wide for the column it's in and has to be wrapped across two or more lines. I've tried a few things, like setting the e.Column.ItemStyle.Wrap = true, but that made no difference at all. I'm going to guess that Internet Explorer is screwing with it in a way that Firefox can cope with happily, and I'm going to assume there's either a CSS or Javascript solution to it that I'm not aware of.

Please see the attached screenshots if this isn't 100% clear. You'll note one doesn't have the detail tables expanded, one does but the line of data in the notes table is small enough that it only stays on one line, and in the other the note is so large it spans across four lines (which I tried to make obvious by using black and grey), and on that one the whole MasterTable shifts the column sizes randomly.

Any help would be appreciated.

Hello,
When i click on column header of the radcalendar it selects all the days of week for that month, ie. When i click on 'W' then it selects all the Wednesdays for that month. But what i want is when i click on 'W' then it should select all the Wednesdays for an entire date range (range i have set using rangemindate and rangemaxdate span across 10 months) after asking a confirmation

For this i have done the following

This works perfectly when selecting dates. Now if i click on the same column header again i want to remove all the "wednesdays" for the entire date range. To remove i have done the following

But this code does'nt remove all the Wednesdays in the date range, it leave behind alternate wednesdays (or which ever day) selected.
Can you advice on this?

-thanks

Hi there,

I have been using the RadCalendar on my webpage.

RadControls for ASP.NET AJAX Q1 2011
version 2011.1.413.35
on a .net 3.5 website

Adding a selected date is easy enough:
        RadCalendar1.SelectedDates.Add(new RadDate(new DateTime(2011, 7, 28)));

Removing a previously added selected date gives an error, however:
        RadCalendar1.SelectedDates.Remove(new RadDate(new DateTime(2011, 7, 28)));
 
Error:
Cannot remove the specified item because it was not found in the specified Collection.
despite the fact that it was added.

Or if I do something like this, it Contains comes back as true, and then remove comes up with the same error.

if (RadCalendar1.SelectedDates.Contains(new RadDate((DateTime)item["CourseDate"]))) {
    RadCalendar1.SelectedDates.Remove(new RadDate((DateTime)item["CourseDate"]));
}

Any ideas?
