Hello,
I use 'RadControls for ASP.NET AJAX Q1 2011 SP2', Windows7 and IE9, I have a problem on the column width of a radgrid.
When I use the document compatibility mode 'EmulateIE7', the width of the columns's header occupies all the grid instead the width of the data items is the value defined. This is a sample to simulate the problem:

<%@ Page EnableEventValidation="false" Language="C#" AutoEventWireup="true" MaintainScrollPositionOnPostback="true"

CodeBehind="Dome1.aspx.cs" Inherits="WebApplication1.Dome1" %>

<%@ Import Namespace="System.Data" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<script runat="server">

protected void RadGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

DataTable dt = new DataTable();

DataRow dr;

int colsNum = 12;

int rowsNum = 10;

string colName = "Column";

for (int j = 1; j <= colsNum; j++)

{

dt.Columns.Add(String.Format("{0}{1}", colName, j));

}

for (int i = 1; i <= rowsNum; i++)

{

dr = dt.NewRow();

for (int k = 1; k <= colsNum; k++)

{

dr[String.Format("{0}{1}", colName, k)] = String.Format("{0}{1} Row{2}", colName, k, i);

}

dt.Rows.Add(dr);

}

(sender as RadGrid).DataSource = dt;

}

</script>

See the attached image:

    - correct.png, without the line:
        '<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

Why the strange rendering with EmulateIE7 mode?

Hi Domenico,

This meta tag forces the IE browser into compatibility mode. You can achieve the same testing mode by using the IE Developer Toolbar, which is activated with shortcut F12, too.

However, could you try to set Width="99%" to the MasterTableView and let me know how it goes?

Additionally, our system indicates that you have opened a support ticket concerning the same issue. In order to avoid duplicate posts, I suggest that we continue the communication in the support thread.

Kind regards,
