Hi! The point is that while scrolling within a datagrid, sometimes the gridloses focus with no reason because I was just scrolling.The attach simply illustrates this(while scrolling you'll get a message) Thank you in advance. ps: I'm using vs.net 2003. using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; namespace test2k3 { /// /// Summary description for Form1. /// public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.DataGrid dg; private DataTable dt; private System.Windows.Forms.Button button1; /// /// Required designer variable. /// private System.ComponentModel.Container components = null; public Form1() { // // Required for Windows Form Designer support // InitializeComponent(); // // TODO: Add any constructor code after InitializeComponent call // dt = new DataTable(); DataColumn dc = new DataColumn("Nr"); dt.Columns.Add(dc); for(int i = 0 ; i < 100; i++) { DataRow dr = dt.NewRow(); dr[0] = "row #"+i; dt.Rows.Add(dr); } this.dg.DataSource = dt; } /// /// Clean up any resources being used. /// protected override void Dispose( bool disposing ) { if( disposing ) { if (components != null) { components.Dispose(); } } base.Dispose( disposing ); } #region Windows Form Designer generated code /// /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// private void InitializeComponent() { this.dg = new System.Windows.Forms.DataGrid(); this.button1 = new System.Windows.Forms.Button(); ((System.ComponentModel.ISupportInitialize)(this.dg)).BeginInit(); this.SuspendLayout(); // // dg // this.dg.DataMember = ""; this.dg.HeaderForeColor = System.Drawing.SystemColors.ControlText; this.dg.Location = new System.Drawing.Point(24, 16); this.dg.Name = "dg"; this.dg.Size = new System.Drawing.Size(160, 128); this.dg.TabIndex = 0; this.dg.Leave += new System.EventHandler(this.dg_Leave); // // button1 // this.button1.Location = new System.Drawing.Point(232, 64); this.button1.Name = "button1"; this.button1.Size = new System.Drawing.Size(56, 32); this.button1.TabIndex = 1; this.button1.Text = "button1"; // // Form1 // this.AutoScaleBaseSize = new System.Drawing.Size(5, 13); this.ClientSize = new System.Drawing.Size(328, 173); this.Controls.Add(this.button1); this.Controls.Add(this.dg); this.Name = "Form1"; this.Text = "Form1"; ((System.ComponentModel.ISupportInitialize)(this.dg)).EndInit(); this.ResumeLayout(false); } #endregion /// /// The main entry point for the application. /// [STAThread] static void Main() { Application.Run(new Form1()); } private void dg_Leave(object sender, System.EventArgs e) { //MessageBox.Show("You haven't leaved the grid.You've been just scrolling!","Is This A Bug?"); } } }
