在gridview中使用dropdownlist的方法

在页面：

<asp:TemplateField HeaderText="公司">

　　<ItemTemplate>

　　　　<asp:DropDownList ID="ddlCompany" runat="server" DataSource="<%# BindCompany() %>" DataTextField="ShortName" DataValueField="Id" OnSelectedIndexChanged="ddlCompany_SelectedIndexChanged" AutoPostBack="true">

　　　　</asp:DropDownList>

</ItemTemplate>

</asp:TemplateField>

在后台：

protected DataTable BindCompany()

{

// 获取公司

BaseOrganizeManager organizeManager = new BaseOrganizeManager(this.UserCenterDbHelper, this.UserInfo);//Nick change database

DataTable dataTable = organizeManager.GetCompanyDT(String.Empty);

// 用过滤器进行过滤，只显示有效的数据。

BaseBusinessLogic.SetFilter(dataTable, BaseOrganizeTable.FieldEnabled, "1");

BaseBusinessLogic.SetFilter(dataTable, BaseOrganizeTable.FieldDeleteMark, "0");

BaseBusinessLogic.SetFilter(dataTable, BaseOrganizeTable.FieldIsInnerOrganize, "1");

DataRow dr;

dr = dataTable.NewRow();

dataTable.Rows.InsertAt(dr, 0);

return dataTable;

}

使用DropDownList：

protected void ddlCompany_SelectedIndexChanged(object sender, EventArgs e)

{

GridViewRow gvr = (GridViewRow)((Control)sender).Parent.Parent;

DropDownList ddlCompany = (DropDownList)gvr.FindControl("ddlCompany");

DropDownList ddlSubOrg = (DropDownList)gvr.FindControl("ddlSubOrg");

DropDownList ddlDept = (DropDownList)gvr.FindControl("ddlDept");

DropDownList ddlWorkgroup = (DropDownList)gvr.FindControl("ddlWorkgroup");

this.GetSubOrgList(ddlCompany.SelectedValue, ddlSubOrg);

this.GetDeptList(ddlCompany.SelectedValue, ddlDept);

this.GetWorkgroupList(ddlSubOrg.SelectedValue, ddlWorkgroup);

}
