asp.net Checbox在GridView中的应用实例分析
本文实例讲述了asp.net Checbox在GridView中的应用方法。分享给大家供大家参考，具体如下：
先看效果图：
前台代码：样式自己定义哦！

后台代码：
protected void HkrGridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
TableCellCollection tcHeader = e.Row.Cells;
tcHeader.Clear();
//第一行表头
tcHeader.Add(new TableHeaderCell());
tcHeader[0].Text = "序号
No.";
tcHeader.Add(new TableHeaderCell());
tcHeader[1].Text = "附件名称";
tcHeader.Add(new TableHeaderCell());
tcHeader[2].Text = "备注";
tcHeader.Add(new TableHeaderCell());
tcHeader[3].Text = "选择";
}
}
protected void HkrGridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
GridViewRow gr = e.Row;
if (e.Row.RowIndex != -1)
{
e.Row.Cells[0].Text = (e.Row.RowIndex + 1).ToString();
}
}
private void HkrGridViewBind(){
string strSql = "SELECT keyId,newName, oldName, localHome,memo FROM aq_file_up WHERE (relaid = @relaid) AND (fjType = @fjType) AND (usestatus = 1)";
SqlParameter[] sps = {
new SqlParameter("@relaid",this.hdnRelaId.Value),
new SqlParameter("@fjType",this.hdnFjType.Value)
};
DataTable dt = pms.SqlHelper.ExecuteDataTable(CommandType.Text, strSql, sps);
tabGridView1.DataSource = dt;
tabGridView1.DataBind();
}
rotected void Button1_Click(object sender, EventArgs e)
{
CheckBoxAll.Checked = false;
CheckBox1.Checked = false;
for (int i = 0; i <= tabGridView1.Rows.Count - 1; i++)
{
CheckBox cb = (CheckBox)tabGridView1.Rows[i].FindControl("CheckBox");
cb.Checked = false;
}
}
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
for (int i = 0; i <= tabGridView1.Rows.Count - 1; i++)
{
CheckBox cb = (CheckBox)tabGridView1.Rows[i].FindControl("CheckBox");
if (cb.Checked == false)
{
cb.Checked = true;
}
else
{
cb.Checked = false;
}
}
//CheckBox1.Checked =true;
CheckBoxAll.Checked = false;
}
protected void CheckBoxAll_CheckedChanged(object sender, EventArgs e)
{
for (int i = 0; i <= tabGridView1.Rows.Count - 1; i++)
{
CheckBox cb = (CheckBox)tabGridView1.Rows[i].FindControl("CheckBox");
if (CheckBoxAll.Checked == true)
{
cb.Checked = true;
}
else
{
cb.Checked = false;
}
}
CheckBox1.Checked = false;
}
