Hi,

private TextBox CreateTextBox(GridViewRow row,int i)
      {

            TextBox txtint = new TextBox();
            txtint.Width = 25;
            txtint.Text = "0";
            txtint.ID = "txtint" + row.RowIndex + i.ToString();
            txtint.TextChanged += new EventHandler(txtint_TextChanged);
            //txtint.Attributes.Add("onBlur", "Addition('" + txtint.ID + "');");
            txtint.Attributes.Add("onBlur", "Addition();");
            txtint.Attributes.Add("onkeyup", "Average();");
          //  this.Page.Controls.Add(txtint);
            return txtint;

}

}

推荐答案

迭代控件

foreach (Control ctrl in Page.Controls)
{
if (ctrl is TextBox)
{
Textbox myTextBox = (TextBox)ctrl;
 // read the ID in myTextBox.ID
// based on ID you know which parameter should have the value from the Text property
}
}

按钮单击事件

In Button Click event

foreach (GridViewRow row in myGridView.Rows)
{
 TextBox txtbox = (TextBox)row.FindControl("txtint" + row.RowIndex.ToString());
}

您需要更改"txtint.ID ="txtint" + row.RowIndex + i.ToString()

到

txtint.ID ="txtint" + row.RowIndex;

希望这会有所帮助！

You need to change "txtint.ID = "txtint" + row.RowIndex + i.ToString()

to

txtint.ID = "txtint" + row.RowIndex;

Hope this helps!
