Hello.
I've created my own CommandItemTemplate and put some custom buttons there, but I still want the caption of mastertableview to be placed in the same TD as buttons, with custom CSS style. How to manage this? Right only I indicate Caption property - radgrid adds additional TR above my command item template with caption centered :(

p.s. How to add custom attribute to MasterTableView? I've inherited from GridTableView. But seems like the same approach with public properties and saving in ControlState that worked out for RadGrid does not work here - setter for new property is not called :(

[ToolboxData("<{0}:DSGridTableView runat=server></{0}:DSGridTableView>")]
public class DSGridTableView : GridTableView
{
    public DSGridTableView()
    {
    }
    public DSGridTableView(RadGrid owner)
        : base(owner)
    {
    }
    //public new string Caption
    //{
    //    get
    //    {
    //        return string.Empty;
    //    }
    //}
    [DefaultValueAttribute("")]
    [PersistenceMode(PersistenceMode.Attribute)]
    public string Title
    {
        get
        {
            return (ControlState["Title"] == null ? string.Empty : (string)ControlState["Title"]);
        }
        set
        {
            ControlState["Title"] = value;
        }
    }
    [DefaultValueAttribute("")]
    [PersistenceMode(PersistenceMode.Attribute)]
    public string TitleCssClass
    {
        get
        {
            return (ControlState["TitleCssClass"] == null ? string.Empty : (string)ControlState["TitleCssClass"]);
        }
        set
        {
            ControlState["TitleCssClass"] = value;
        }
    }
}

Hello Alexander,

The caption's HTML rendering and position is determined by the browser and it is always at the top of the <table>. So there is no way to switch the places of the caption and the CommandItemTemplate, unless you actually move the contents of the CommandItemTemplate outside RadGrid.

As for the custom GridTableView - you have created a custom TableView class, but the RadGrid is not using it, that's why the property setters are not called. You can try using a custom RadGrid control and change the type of its MasterTableView property.

Sincerely yours,

Hi! I already tried to override MasterTableView in my grid, but when I did it - the grid completely disappeared from my page. What I did wrong?
    public partial class DSGridView : RadGrid
    {
public override GridTableView MasterTableView
{
get
{
return new DSGridTableView(this);
}
}
	....
    }

Hello Alexander,

Actually you need to override the CreateTableView method, sorry:

Hi, i already tried this and then my custom 'subgrid' appears under DetailTables. But I don't use DetailTables, I want to use MasterTableView only. But that one I cannot override...

Hi Alexander,

The following works. Please compare with your implementation.

<script runat="server">
 
protected void RadGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    DataTable dt = new DataTable();
    DataRow dr;
    int colsNum = 4;
    int rowsNum = 3;
    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>
