4、自带分页
复制代码 代码示例:
#region自带分页
protected void FollowExamInfoGridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
FollowExamInfoGridView.PageIndex = e.NewPageIndex;
BindFollowExamInfoGridView(Convert.ToInt32(HiddenPersonID.Value));
}
#endregion
5、选中Grid View 的实现
复制代码 代码示例:
#region实现选中行
<SelectedRowStyle BackColor="AliceBlue" ForeColor="Gray" />
<asp:CommandField ShowSelectButton="True"/>
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes.Add("onclick", "this.cells[0].childNodes[0].click()");
}
protected void GridViewRegiment_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridViewRegiment.SelectedRow;
int RegimentID = Convert.ToInt32(row.Cells[1].Text);
Response.Redirect("UpdateRegimentation.aspx?RegimentID=" + RegimentID);
}
#endregion
6、显示颜色和删除
复制代码 代码示例:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
//int i;
//for (i = 0; i < GridViewRegiment.Rows.Count; i++)
//{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//当有编辑列时，避免出错，要加的RowState判断
if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
{
((ImageButton)e.Row.Cells[2].FindControl("IBtndelete")).Attributes.Add("onclick", "
javascript:return confirm('你确认要删除："" + e.Row.Cells[0].Text + ""吗?')");
}
e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#00A9FF'");
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#E6F5FA'");
}
//}
}
7、GridView空的处理
1）、显示无表头的空纪录，EmptyDataText="没有记录"
2）、显示表头的空纪录
复制代码 代码示例:
DataTable dt = new DataTable();
dt = feibf.GetByPersonIDFollowExamInfo(PersonID); //查询指定人的随访信息记录
DataView dv = SortBindGrid(dt);
if (dt.Rows.Count > 0)
{
FollowExamInfoGridView.DataSource = dv;
FollowExamInfoGridView.DataBind();
}
else
{
//添加新行显示表头
dt.Rows.Add(dt.NewRow());
FollowExamInfoGridView.DataSource = dt;
FollowExamInfoGridView.DataBind();
//处理新行
int columnCount = FollowExamInfoGridView.Rows[0].Cells.Count;
//清除掉该空行的全部单元格
FollowExamInfoGridView.Rows[0].Cells.Clear();
//新建单元格对象
FollowExamInfoGridView.Rows[0].Cells.Add(new TableCell());
//合并单元格
FollowExamInfoGridView.Rows[0].Cells[0].ColumnSpan = columnCount;
//设置单元格提示内容
FollowExamInfoGridView.Rows[0].Cells[0].Style.Value = "text-align:center";
FollowExamInfoGridView.Rows[0].Cells[0].Text = "此人无随访信息";
}
