GridView是VS2005中對VS2003的DataGrid的增強替代控件
下面展示一下它的基本常見應用
效果圖如下：
[查詢]按鈕：查詢數據庫 ，顯示信息Table 並 綁定GridView
//查詢按鈕
protected void btnQue_Click(object sender, EventArgs e)
{
this.tableInfo.Visible = true;
SqlConnection sqlconn = new SqlConnection("server=localhost;database=db;uid=uid;pwd=pwd;");
sqlconn.Open();
SqlDataAdapter sda = new SqlDataAdapter("select * from table", sqlconn);
DataSet ds = new DataSet();
sda.Fill(ds);
this.grvInfo.DataSource = ds;
this.grvInfo.DataBind();
sda.Dispose();
ds.Dispose();
sqlconn.Close();
}
[全選]按鈕：
//全選
protected void btnAllCh_Click(object sender, EventArgs e)
{
foreach(GridViewRow currow in grvInfo.Rows)
{
((CheckBox)currow.Cells[0].Controls[1]).Checked = true;
}
}
類似的[取消全選]的編碼為：
// 取消全選
protected void btnNoCh_Click(object sender, EventArgs e)
{
foreach (GridViewRow currow in grvInfo.Rows)
{
((CheckBox)currow.Cells[0].Controls[1]).Checked = false;
}
}
[明細]按鈕：
該按鈕的操作，要寫在GridView ROW按鈕事件--- RowCommand
// GridView ROW按鈕事件 RowCommand
protected void grvInfo_RowCommand(object sender, GridViewCommandEventArgs e)
{
if(e.CommandName.Equals("mingxin"))
{
ImageButton lb = (ImageButton)e.CommandSource;
GridViewRow curgvr = (GridViewRow)lb.Parent.Parent;
string paraValue = curgvr.Cells[2].Text.ToString();
//RegisterClientScriptBlock("openmingxin", "<script language='javascript'>window.open(src='mingxin.aspx?pihao="+ paraValue+"','newwindow','');</script>");
ClientScript.RegisterClientScriptBlock(this.GetType(), "aa", "<script language='javascript'>alert("+paraValue +"');</script>");
}
}
[刪除]按鈕：
可以在HTML原始檔中加上
<asp:BoundField HeaderText="審核" />
<asp:TemplateField HeaderText="刪除">
<ItemStyle HorizontalAlign="Center" />
<ItemTemplate>
<asp:ImageButton runat="server" ImageUrl="~/image/del.JPG" ID="delid" CommandName="del" OnClientClick="return confirm('確實要刪除嗎？');" />
</ItemTemplate>
</asp:TemplateField>
同時也可以如[明細]按鈕在GridView ROW按鈕事件--- RowCommand 對[刪除]點擊按鈕的事件進行服務器端處理!
