HI,
I have a radgrid, a search button and tetxbox to enter my search term in and a table in db with like 50,000 records.
I ajaxified my grid which means that during paging I get to see this whirly on the screen and it all looks good. My question is that what happens for the first time when I enter the key and hit the search button. Right now my grid does not appear and there is no indication on the grid as if it is waiting for the data...any comments or ideas...? ANy help would be appreciated..

Thanks.

• I am using MS Visual Studio 2010 in a 3.5 environment.
• I am using Microsoft Vista (32 bit)
• The database is currently located on an SQL 2005 server.
• I am using RadGrid & tools, version 2012.1.411.35
• I am using both Chrome (18.0.1025.168) and Internet Explorer (8.0.7600.16385)
• I am programming in VB.net

I am usiing the radScheduler to display full day events that can last 1 or more days.  I am setting the background and border colors for the items based on content.  Where this is failing me is when the item continues to the next day.  When this happens, the border and background disappear.

This only fails in Month View.  In Day view the colors are there for each day.  Week view draws the appointment across all days.

The attached image shows this to be the case for items 52 & 53 which should last from Jun 8th to Jun 15th.  The database values driving the start and date are:

2012-06-08 00:00:00.000
2012-06-16 00:00:00.000

My Markup and code are below:

Hi, the RadNotification tool looks extremely useful for my application, but I am having some trouble understanding how to have it do what I want. I want to essentially perform a 'check' every 60 seconds, which will see if there are any new rows in a certain table. if there are, I want to tell the user and show them some details of this row - if not I don't want the notification to show.

Here's what I have currently:




This 'sort of' works, but the notification pops up for a a very short time then disappears if the value is 0, when I want it to not show it at all.

Hi:

I'd like to use RadGrid in a Web App that I'm building.  Is there a way that I can hide/show certain columns based on the width of the screen?  I currently use CSS to change the layout considerably when  the screen goes below a certain width - i.e.  @media only screen and (max-width: 850px)

Any suggestions would be greatly appreciated.

Hi everyone, 

Short description:  See the code below...  How do I make my RadWindow open and close via AJAX without breaking its ajaxified content? 


Long description:  

I have a RadWindow, an "Open Window" button, and a Literal.  The open button (no AJAX) opens the RadWindow by toggling its VisibleOnPageLoad property*.  

In the RadWindow, which uses ContentTemplate, there is a RadAjaxPanel and a "Close Window" button.  The close button (no AJAX) closes the RadWindow by toggling its VisibleOnPageLoad property*.  

*I do a server-side window open/close because I want to so some other server-side stuff on the button click event.   

The RadAjaxPanel contains a DropDownList and two Panels ("A" and "B").  The dropdown toggles the visibility of the two panels via AJAX.  When the Close button is clicked, the Literal's Text is changed to that of the dropdown's SelectedItem text.  

So, after the page posts...  

I click the Open Window button.  It does a full postback and the RadWindow is displayed.  I change the dropdown from "A" to "B".  It does an async postback, Panel A disappears, Panel B is displayed.  I click the Close button, it does a full postback, the window disappears, and the literal's text is changed to "You selected B".  

Now I want the RadWindow to open and close via AJAX, but all my attempts to get it working with RadAjaxManager have failed.  The technique for server side RadWindow open/close that I've been using breaks the RadWindow's content AJAX (it does a full postback when I change the dropdown).  

How do I make my RadWindow open and close via AJAX without breaking its ajaxified content?

Page markup:  

Page codebehind: 

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    if (!IsPostBack)
    {
        this.TestDropdown.SelectedValue = "A";
    }
}
protected override void OnPreRender(EventArgs e)
{
    base.OnPreRender(e);
    this.PanelA.Visible = this.TestDropdown.SelectedValue.Contains('A');
    this.PanelB.Visible = this.TestDropdown.SelectedValue.Contains('B');
}
protected void OpenButton_Click(object sender, EventArgs e)
{
    //Do some server-side stuff first
    this.Window.VisibleOnPageLoad = true;
}
protected void CloseButton_Click(object sender, EventArgs e)
{
    this.OutputLiteral.Text = string.Format("You selected {0}", this.TestDropdown.SelectedItem.Text);
    this.Window.VisibleOnPageLoad = false;
}

Thank you

I've observed that spaces in text are being removed in my radGrid when retrieving using javascript. The spaces are present in the html, just not able to get the full data when I retrieve it. I'm using code similar to what is documented in Telerik documentation.
http://www.telerik.com/help/aspnet-ajax/grid-getting-cell-values-for-selected-rows-client-side.html

Specifically, I have text similar to "A  B", where there are two spaces between A and B, but code only returns 1 of the spaces. Is this a bug in Telerik javascript functions, or am I doing something wrong?

Snippet of code relevant to my issue is below.

I have a simple 2 column grid with startswith filters and a filterdelay set to 500. It works correctly as long as the grid is not in a Ajax Panel. Once it is in a Ajax panel. it will only sort on the first column selected.

Hi there

I have run into the strangest problem.

I have two RadGrid's with NestedTemplates on two separate pages.

When I log in as my admin user they both work fine, but when I log in with a different user they don't want to expand?

The users are accessing the SAME pages, all that differs is one query that populates the MainTable in one of the grids. The second client page is EXACTLY the same regardless of the user logged in, but yet, they can't expand the Nested Rows?

I am totally confused and can't think of any reason this should be happening?
