GridView的一些技巧总结
这里记录下经常用到的三个方法
1.GridView_RowCreated
1
protected void gridview_RowCreated(object sender, GridViewRowEventArgs e)
2
{
3
if (e.Row.RowType == DataControlRowType.DataRow)
4
{
5
6
LinkButton linkbutton = (LinkButton)e.Row.FindControl("lbtn");
7
linkbutton.CommandArgument = e.Row.RowIndex.ToString();
8
}
9
}
2.GridView_RowDataBound
protected void gridview_RowCreated(object sender, GridViewRowEventArgs e)2
{3
if (e.Row.RowType == DataControlRowType.DataRow)4
{5
6
LinkButton linkbutton = (LinkButton)e.Row.FindControl("lbtn");7
linkbutton.CommandArgument = e.Row.RowIndex.ToString();8
}9
}前提条件是在第0列放置一个visble为false的模版列,里面内容为Label,捆绑着表的ID
1
protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
2
{
3
if (e.Row.RowType == DataControlRowType.DataRow)
4
{
5
LinkButton linkbutton = (LinkButton)e.Row.FindControl("lbtn");
6
int id = Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "ID").ToString());
7
//获取了ID后使用业务方法
8
linkbutton.Text = //指定模版列的控件
9
}
10
//鼠标移动变颜色
11
for (int i = -1; i < GridView.Rows.Count; i++)
12
{
13
//当鼠标停留时更改背景色
e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#B5C9DD'");
14
//当鼠标移开时还原背景色
15
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");
16
}
17
}
3.GridView_RowCommand
protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)2
{3
if (e.Row.RowType == DataControlRowType.DataRow)4
{5
LinkButton linkbutton = (LinkButton)e.Row.FindControl("lbtn");6
int id = Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "ID").ToString());7
//获取了ID后使用业务方法8
linkbutton.Text = //指定模版列的控件9
}10
//鼠标移动变颜色11
for (int i = -1; i < GridView.Rows.Count; i++) 12
{13
//当鼠标停留时更改背景色 e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#B5C9DD'");
14
//当鼠标移开时还原背景色15
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");16
}17
}前提条件是在第0列放置一个visble为false的模版列,里面内容为Label,捆绑着表的ID
1
protected void GridView_RowCommand(object sender, GridViewCommandEventArgs e)
2
{
3
if (e.CommandName == "commandname")
4
{
5
int index = Convert.ToInt32(e.CommandArgument);
6
GridViewRow row = GridView.Rows[index];
7
int id = Int32.Parse(((Label)row.FindControl("ID")).Text);
8
}
9
}
protected void GridView_RowCommand(object sender, GridViewCommandEventArgs e)2
{3
if (e.CommandName == "commandname")4
{ 5
int index = Convert.ToInt32(e.CommandArgument);6
GridViewRow row = GridView.Rows[index];7
int id = Int32.Parse(((Label)row.FindControl("ID")).Text);8
}9
}
