1.主要是对gridview 事件说明；
aspx：
<form id="form1" runat="server">
<input type="text" id="text_id" value="23" />
<div>
</div>
<asp:GridView ID="GridView1" runat="server"
onrowdatabound="GridView1_RowDataBound" ondatabound="GridView1_DataBound"
onrowcreated="GridView1_RowCreated">
</asp:GridView>
</form>
<script>
function getvalue(objtext) { document.getElementById("text_id").value = objtext; }
</script>
cs;
protected void Page_Load(object sender, EventArgs e) {
this.GridView1.DataSource = GetDataTable();
this.GridView1.DataBind();
}
//数据源构造
public System.Data.DataTable GetDataTable()
{
System.Data.DataTable dt = new System.Data.DataTable();
dt.Columns.Add("Id", typeof(int));
dt.Columns.Add("Name",typeof(string));
dt.Columns.Add("Sex",typeof(int));
for (int i = 0; i < 20; i++)
{
dt.Rows.Add(i, "lin.su" + i,i%2==0?0:1);
}
dt.AcceptChanges();
return dt;
}
//数据行绑定事件
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) {
if (e.Row.RowType == DataControlRowType.DataRow)
{
//鼠标经过时，行背景色变
e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
//鼠标移出时，行背景色变
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");
//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)
{
e.Row.Attributes.Add("onclick", "getvalue('" + e.Row.Cells[0].Text + "')");
}
}
}
//创建行事件 主要是生成表头
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
switch (e.Row .RowType)
{
case DataControlRowType.Header:
TableCellCollection tabcollention = e.Row.Cells;
tabcollention.Clear();
tabcollention.Add(new TableHeaderCell());
tabcollention[0].Text = "编号";
tabcollention.Add(new TableHeaderCell());
tabcollention[1].Text = "名称";
tabcollention.Add(new TableHeaderCell());
tabcollention[2].Text = "性别";
break;
}
}
//gridview 绑定数据事件
protected void GridView1_DataBound(object sender, EventArgs e)
{
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
if (Convert.ToInt16(GridView1.Rows[i].Cells[2].Text) == 0) //sex
{
GridView1.Rows[i].Cells[2].BackColor = System.Drawing.Color.Red;
GridView1.Rows[i].Cells[2].Text = "男";
}
else
{
GridView1.Rows[i].Cells[2].BackColor = System.Drawing.Color.Yellow;
GridView1.Rows[i].Cells[2].Text = "女";
}
}
}
