Gridview下拉列表 [英] Gridview DropdownList

问题描述

我在gridview中添加了一列，即Dropdownlist

I added one column to gridview that is Dropdownlist

<asp:TemplateField HeaderText="ramesh" >
      <ItemTemplate>
          <asp:DropDownList ID="ddlName"  DataTextField="job_desc"

                  Width="100" runat="server">
          </asp:DropDownList>
       </ItemTemplate>
</asp:TemplateField>

如何将datatable列绑定到该Gridview DropDownList列表.

How to bind datatable column to that Gridview DropDownList list.

推荐答案

在这里:
在ASP.NET 2.0(C#)中将DropDownList嵌套到Gridview [ ^ ]

就像这样:

Here you go:
Nesting the DropDownList to Gridview in ASP.NET 2.0(C#)[^]

It would be something like:

if (e.Row.RowType == DataControlRowType.DataRow)
{
categoryid = Int32.Parse(e.Row.Cells[0].Text);
expression = "categoryid = " + categoryid;
DropDownList ddl = (DropDownList)e.Row.FindControl("dropdownlist1");
DataRow[] rows = ds.Tables[0].Select(expression);

foreach (DataRow row in rows)
{
DataRow newrow = mytable.NewRow();
newrow["productid"] = row["productid"];
newrow["productname"] = row["productname"];
mytable.Rows.Add(newrow);
}
ddl.DataSource = mytable;
ddl.DataTextField = "productname";
ddl.DataValueField = "productid";
ddl.DataBind();
}
