1.前台代码如下,DataKeyNames中设置为“ID”
<asp:GridView ID="gvListDoc" runat="server" CssClass="grid" AutoGenerateColumns="False"
DataKeyNames="ID" OnRowDataBound="gvListDoc_RowDataBound">
<Columns>
<asp:TemplateField>
<ItemStyle Width="40" HorizontalAlign="Center"></ItemStyle>
<HeaderTemplate>
<input type="checkbox" id="ckAll" onclick="allOrNot('gvListDoc', this.checked)">
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="cbSel" runat="server"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField HeaderText="序号">
<ItemStyle HorizontalAlign="Center" Width="40"></ItemStyle>
</asp:BoundField>
<asp:BoundField HeaderText="编码" DataField="Code">
<ItemStyle Width="150" HorizontalAlign="Center"></ItemStyle>
</asp:BoundField>
<asp:BoundField HeaderText="标题" DataField="Name"></asp:BoundField>
</Columns>
<EmptyDataTemplate>
<div class="tip">
暂无记录!</div>
</EmptyDataTemplate>
</asp:GridView>
2.在进行数据绑定时,将获取的ID值赋给其属性
protected void gvListDoc_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes["onmouseover"] = "this.style.backgroundColor='#ECFEDD'";
e.Row.Attributes["onmouseout"] = "this.style.backgroundColor=''";
e.Row.Cells[1].Text = (e.Row.RowIndex + 1).ToString();
string id = this.gvListDoc.DataKeys[e.Row.RowIndex]["ID"].ToString();
e.Row.Attributes.Add("ID", id);
}
}
3.前台获取ID属性
var dg = document.getElementById(gvListDoc);
var id=dg.rows[i].id;
进而可以用ID进行其他操作!
