我有一个嵌套的
Gridiew
。家长显示 customers
,孩子显示该 customer
的每个部分。
信息:
grdViewCustomers
显示 customers
。grdviewordersofcustomer
显示每个 customer
的部件。
在
ChildGridview
中,我有一个 RadioButtonList
,因此您可以选择它是什么零件类型。
我有
ChildGridview
和父级数据绑定,使用 grdviewcustomers_onrowdatabound
中的 .cs
。
我可以从
RadioButtonList
获得价值。但是我无法从 SQL 中提取数据并在页面加载时设置为适当的值。有人可以帮忙吗?我感觉很接近,但还没有金牌。
protected void grdViewCustomers_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string customerID = grdViewCustomers.DataKeys[e.Row.RowIndex].Value.ToString();
GridView grdViewOrdersOfCustomer = (GridView)e.Row.FindControl("grdViewOrdersOfCustomer");
grdViewOrdersOfCustomer.DataSource = SelectData("select * from [dbo].[View_Budget_Setup_2_Items] WHERE CUSID='" + customerID + "' order by id_item");
grdViewOrdersOfCustomer.DataBind();
foreach (GridViewRow rowChild in grdViewOrdersOfCustomer.Rows)
{
string ChildID = grdViewOrdersOfCustomer.DataKeys[rowChild.RowIndex].Value.ToString();
string Editable = dbUtilities.SalesEditableID(ChildID);
if (Editable == "Bud")
{
// Set values here
}
}
grdViewOrdersOfCustomer.DataBind();
//testing
}
}

您应该将每个内容的代码移至 grdViewOrdersOfCustomer GridView 的 onrowdatabound 事件,以便在绑定后获得每一行。
protected void grdViewCustomers_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string customerID = grdViewCustomers.DataKeys[e.Row.RowIndex].Value.ToString();
GridView grdViewOrdersOfCustomer = (GridView)e.Row.FindControl("grdViewOrdersOfCustomer");
grdViewOrdersOfCustomer.DataSource = SelectData("select * from [dbo].[View_Budget_Setup_2_Items] WHERE CUSID='" + customerID + "' order by id_item");
grdViewOrdersOfCustomer.DataBind();
}
}
protected void grdViewOrdersOfCustomer_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string ChildID = (GridView)sender.DataKeys[e.row.RowIndex].Value.ToString();
string Editable = dbUtilities.SalesEditableID(ChildID);
if (Editable == "Bud")
{
// Set values here
}
}
}
绑定单选按钮列表时,您可以在 aspx 代码上执行此操作,如下所示:
<asp:RadioButtonList ID="RadioCusListC" runat="server" SelectedValue='<%# eval("ColumnName")%>'>
<asp:ListItem>DNB</asp:ListItem>
<asp:ListItem>B/G</asp:ListItem>
<asp:ListItem>B/O</asp:ListItem>
<asp:ListItem>BUD</asp:ListItem>
</asp:RadioButtonList>
请记住,如果您获取的值与查询中的值不同,您将会收到错误。
您还可以找到 grdViewOrdersOfCustomer_OnRowDataBound 上的控件并执行以下操作:
RadioCusListC.Items.FindByValue(Editable).Selected = [True]
