选中Grid View 的实现

复制代码 代码如下:

#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)

{

int RegimentID = Convert.ToInt32(row.Cells[1].Text);

Response.Redirect("UpdateRegimentation.aspx?RegimentID=" + RegimentID);

#endregion

显示颜色和删除

复制代码 代码如下:

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'");

}

//}

}

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 代码如下:

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";

}

GridView 的导出

EnableEventValidation="false"

复制代码 代码如下:

#region导出

public override void VerifyRenderingInServerForm(Control control)

{

}

protected void BtnPrint_Click(object sender, EventArgs e)

{

Response.Clear();

Response.Buffer = true;

Response.Charset = "GB2312";

Response.AppendHeader("Content-Disposition", "attachment;filename=FileName.xls");

// 如果设置为GetEncoding("GB2312");导出的文件将会出现乱码！！！

Response.ContentEncoding = System.Text.Encoding.UTF7;

Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。

System.IO.StringWriter oStringWriter = new System.IO.StringWriter();

System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
