我正在使用Outward Challan Detail，我需要通过gridview在表单上显示结果。
我的问题是我不知道如何为textbox中存在的gridview分配值。
如何使用dataReader或DataSet在我的textbox templates fields内的gridview中分配值？
这是我的 aspx
<div id="OutDCItemDetails" runat="server" style="overflow:auto">
<asp:Panel ID="PanelOutDCItemDetails" runat="server">
<asp:GridView ID="gvOutDCItemDetails" runat="server" AllowPaging="True"
PageSize="6" AutoGenerateColumns="False"
onrowdatabound="gvOutDCItemDetails_RowDataBound"
onrowcommand="gvOutDCItemDetails_RowCommand"
onselectedindexchanged="gvOutDCItemDetails_SelectedIndexChanged"
BackColor="White" BorderColor="White" BorderStyle="Ridge" BorderWidth="2px"
CellPadding="3" CellSpacing="1" GridLines="None" DataKeyNames="Item_Id" >
<Columns>
<asp:CommandField ShowDeleteButton="True" />
<asp:BoundField HeaderText="Item Id" DataField="Item_Id" />
<asp:BoundField HeaderText="Item Name" DataField="IName" />
<asp:BoundField HeaderText="Net Quantity" DataField="I_Quantity" />
<asp:BoundField DataField="Remaining_Qty" HeaderText="Remaining Quantity" />
<asp:TemplateField HeaderText="Process">
<ItemTemplate>
<asp:DropDownList ID="ddrProcess" runat="server" >
</asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Dispatch Quantity">
<ItemTemplate>
<asp:TextBox ID="txtDispatchQuantity" runat="server" AutoPostBack="true" OnTextChanged="TextChanged_txtDispatchQuantity"></asp:TextBox></ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Remaining Quantity">
<ItemTemplate>

</asp:TemplateField>
<asp:TemplateField>

</ItemTemplate>
</asp:TemplateField>
</Columns>

您应该将DataTable列直接绑定到TextBox内的TemplateField，例如......
<asp:TextBox ID="txtDispatchQuantity" runat="server" Text='<%# Eval("ColumnNameInDataSetTable") %>' />
这直接将值绑定到TextBoxes。您可以为所有其他TextBoxes执行此操作。
答案 1 :(得分：0)
TextBox txtDispatchQuantity = (TextBox)e.Row.FindControl("txtDispatchQuantity");
var dataRow = (DataRowView)e.Row.DataItem;
var Dispatch_Qty = "Dispatch_Qty";
var check = dataRow.Row.Table.Columns.Cast<DataColumn>().Any(x => x.ColumnName.Equals(Dispatch_Qty, StringComparison.InvariantCultureIgnoreCase));
if (check)
{
// Property available
txtDispatchQuantity.Text =ds1.Tables[0].Rows[0][7].ToString();
}

使用简单选择和内部选择的一种简短方法，用于没有代码后置的ASPX代码：
....
<ItemTemplate>
<tr>
<td>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("COrder") %>' />
</td>
<td>
<asp:Label ID="TitleLabel" runat="server" Text='<%# Eval("CText") %>' />
</td>
<td>
<a href='<%# "HomeProducts.aspx?Delete=" & Eval("RId")%>' class="btn btn-danger btn-sm RedBtn btn-delete">Delete</a>
</td>
</tr>
</ItemTemplate>
....
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT [RId],[CId],[COrder],[CText]=(SELECT [Title] from [Categories] where [ID]=[HomeProduct].[CId]) FROM [HomeProduct] ORDER BY [COrder] DESC"></asp:SqlDataSource>
