next item navigation in asp.net

Question

I have a program in which items details are displaying. When I press next button it will display next item. the code is working, but when I press next until the last item in the row, the program shows error. So how to stop it wen it reaches the last row.

protected void Button2_Click(object sender, EventArgs e)

{

int i = ViewState["cnt"] !=null ? (int)ViewState["cnt"] : 0;

i = i + 1;

TextBox1.Text = GridView1.Rows[i].Cells[1].Text;

TextBox2.Text = GridView1.Rows[i].Cells[2].Text;

TextBox3.Text = GridView1.Rows[i].Cells[31].Text;

TextBox4.Text = GridView1.Rows[i].Cells[5].Text;

ViewState["cnt"] = i;

}

protected void Button2_Click( object sender EventArgs e) { int i = ViewState[ cnt ] != null ? ( int )ViewState[ cnt ] : 0; //add this line to check row condition if( GridView1.rows.count ) { i = i + 1; TextBox1.Text = GridView1.Rows[i].Cells[1].Text; TextBox2.Text = GridView1.Rows[i].Cells[2].Text; TextBox3.Text = GridView1.Rows[i].Cells[31].Text; TextBox4.Text = GridView1.Rows[i].Cells[5].Text; ViewState[ cnt ] = i; } }

1)Take one variable and store count of rows in gridview int count=this.gridView1.Rows.Count.ToString(); 2)after i=i+1 statement.... check one condition if(i { --add here all remaining code statements...... } this will work for u...... :)
