    Custom control for telerik grid view in winforms

     In my Windows forms control library:

    for MyGrid.cs (where MyGrid.cs is a component class)

    public MyGrid : ` Telerik.WinControls.UI.RadGridView`

    I build and i have MyGrid.dll & i have added that in my visual studio toolbox (also referenced that dll in my consuming winform app).

    Consuming winform app:

    1. In Form1.cs, i drag and drop that MyGrid  & i write this code:

    >     MyGrid1.DataSource=ds.Table[0]; //Dataset

    The grid doesn't get bound with records, whereas when i check ds `row count it has 150 records`. The grid however shows me green and white color (ie. alternating row color), but doesn't bind the data.

    This is the code that consuming winform uses

           DataSet ds  = null;
           string connectionString = "Data Source=test;Initial Catalog=DBname;Integrated Security=True";
            string sql = " SELECT ID,FirstName from table1 ";
            SqlConnection connection = null;            

             connnection = new SqlConnection(connectionString);
             SqlDataAdapter dataadapter = new SqlDataAdapter(sql, connection);
             ds= new System.Data.DataSet();
             dataadapter.Fill(ds, "Table1");
             MyGrid1.DataSource = ds.Tables[0];

    where MyGrid1 is the custom control that is being dragged and dropped from toolbox.

    Custom control code:
                this.EnableAlternatingRowColor = true;
                this.TableElement.AlternatingRowColor  = System.Drawing.Color.Green;            
                this.MasterTemplate.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;
                this.AutoGenerateColumns = true;

    The telerik grid is not binding the data, however when i click on the cell, it shows me the value. Any thoughts?

    Hi Karthick,

    We experienced similar issues in old versions of RadGridView. However, I am not able to reproduce it with our latest release - Q3 2011 SP1. That is why I recommend that you try our latest release. If the issue continues to appear, please send us your application and we will try to locate it and to find a proper solution.

    Should you have any other questions, please do not hesitate to ask.
