ASP.NET GridView控件绑定数据问题

只能显示数据库中的一条数据（第一条或最后一条），请高手指教（gvStuInfo是GridView控件的名称）

public partial class HouAdmin_zhuce_stu : System.Web.UI.Page
{
Datacon dataconn = new Datacon();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dataconn.ecadabindinfostring(gvStuInfo, "select * from tb_Student ", "ID");
}
}

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvStuInfo.PageIndex = e.NewPageIndex;
dataconn.ecadabind(gvStuInfo, "Select * From tb_Student Where "
+ ddlStuID.SelectedValue + " Like '%" + txtSelect.Text + "%'");
}
protected void Button1_Click(object sender, EventArgs e)
{
if (txtSelect.Text == "")
{
dataconn.ecadabindinfostring(gvStuInfo, "select * from tb_Student ", "ID");
}
else
{
dataconn.ecadabind(gvStuInfo, "Select * From tb_Student Where "
+ ddlStuID.SelectedValue + " Like '%" + txtSelect.Text + "%'");
}
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
dataconn.eccom("delete from tb_Student where ID='" + gvStuInfo.DataKeys[e.RowIndex].Value + "'");
Page.Response.Redirect("zhuce_stu.aspx");
}

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[4].Text = Convert.ToString(Convert.ToDateTime(e.Row.Cells[4].Text).ToShortDateString());
}
}
protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e)
{
if (TreeView1.SelectedNode.Text == "退出系统")
{
Response.Write("<script lanuage=javascript>window.close();location='javascript:history.go(-1)'</script>");
}
}
}

Answer 4

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[4].Text = Convert.ToString(Convert.ToDateTime(e.Row.Cells[4].Text).ToShortDateString());
}
}
怎么只判断绑定一列？其他列都不绑定了？
还有e.Row.RowType == DataControlRowType.DataRow这个描述不对吧，这里我记得是两个判断，一个判断的话不能实现。还有个应该是判断e.row的数据类别是不是绑定列，你可以去vs里面找找，我记不清楚是怎么写的了。
