Question

尝试在asp.net中创建下拉列表时出错。希望你们能帮忙，因为我不知道还有什么可以尝试..
错误：＆＃34; system.data.datarowview＆＃39;不包含名称为＆＃39; Suppstatus＆＃39;。＆＃34;的财产，听起来像拼写错误但我已经检查过。

模板代码：

                     <asp:TemplateField>
                    <ItemTemplate>
                    <asp:Label Text='<%#Eval("Suppstatus") %>' Visible="false" ID="lblsuppStatus" runat="server" />
                    </ItemTemplate>
                    <EditItemTemplate>
                    <asp:DropDownList runat="server" ID="ddlSupStatus"> </asp:DropDownList>
                    </EditItemTemplate>
               </asp:TemplateField>

代码背后：

        protected void grvSupplierStatus_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            try
            {
                if (e.Row.RowType == DataControlRowType.DataRow && GridView1.EditIndex == e.Row.RowIndex)
                {
                    DropDownList ddlSupStatus = (DropDownList)e.Row.FindControl("ddlSupstatus");
                    Label lblsuppstatus = (Label)e.Row.FindControl("lblsuppStatus");
                    DataSet ds = new DataSet();
                    ds = GetYesNoValue("Suppstatus");
                    DataTable dt = new DataTable();
                    dt = ds.Tables[0];
                    ddlSupStatus.DataSource = dt;
                    ddlSupStatus.DataTextField = "Suppstatus";
                    ddlSupStatus.DataValueField = "Suppstatus";
                    ddlSupStatus.DataBind();
                    ddlSupStatus.Items.FindByValue(lblsuppstatus.Text).Selected = true;

                }

            }
            catch (Exception ex)
            {
            }

        }  

        public DataSet GetYesNoValue(string ColumnName)
        {
            DataTable dtVal = new DataTable();
            DataColumn column;
            DataRow row;

            column = new DataColumn();
            column.DataType = System.Type.GetType("System.String");
            column.ColumnName = ColumnName;
            dtVal.Columns.Add(column);

            DataSet dsVal = new DataSet();

            dtVal.Rows.Add("--Select--");
            dtVal.Rows.Add("Yes");
            dtVal.Rows.Add("No");

            dsVal.Tables.Add(dtVal);

            return dsVal;
        }

您正在使用迂回方法插入数据。你也可以

替换

<asp:DropDownList runat="server" ID="ddlSupStatus" ></asp:DropDownList>

带

<asp:DropDownList runat="server" ID="ddlSupStatus" Selected='<%# Bind("Suppstatus") %>'> 
   <asp:ListItem Text="--Select--" Value="--Select--"></asp:ListItem>
   <asp:ListItem Text="Yes" Value="Yes"></asp:ListItem>
   <asp:ListItem Text="No" Value="No"></asp:ListItem> 
</asp:DropDownList>

没有任何动作代码隐藏

Gridview，system.data.datarowview＆＃39;不包含属性
