我正在使用Repeater控件在仪表板上生成表。在转发器中,是一个网格视图,用于显示项目详细信息。在GridView的第一列中,gridview是一个下拉列表,用于选择一个项目,在该项目的选定索引上,我正在获取项目详细信息,并且为每个表继续进行计费。现在的问题是,我只能在第一个转发器中获得商品详细信息。当我在另一个表或中继器中选择一个项目时,什么也没有发生。请帮我解决这个问题。
这是我的ASPX标记:
<div class="row">
<asp:Repeater ID="rptrTables" runat="server" OnItemDataBound="rptrTables_ItemDataBound">
<ItemTemplate>
<div class="col-md-6">
<div class="card card-info">
<div class="card-header with-border">
<h3 class="card-title"><asp:Label ID="lblTableNumber" runat="server" Text='<%# Eval("TableName") %>'></asp:Label></h3>
<div class="card-tools">
<button type="button" class="btn btn-tool" data-widget="collapse"><i class="fa fa-minus"></i></button>
</div>
</div>
<div class="card-body">
<div class="row">
<div class="col-md-12">
<div class="form-group">
<asp:GridView ID="grdOrder" runat="server" AutoGenerateColumns="false" AllowPaging="true" CssClass="table table-bordered table-hover table-responsive" GridLines="None" PageSize="10" OnRowDataBound="gvRowDataBound">
<Columns>
<asp:CommandField ShowDeleteButton="true" ControlStyle-CssClass="btn btn-danger fa fa-trash" DeleteText="" HeaderText="Remove" />
<asp:BoundField DataField="RowNumber" HeaderText="Sl. No." />
<asp:TemplateField HeaderText="Item Name">
<ItemTemplate>
<asp:DropDownList ID="drpItemname" runat="server" CssClass="form-control select2" OnSelectedIndexChanged="GetItemDetails" AutoPostBack="true"></asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Price">
<ItemTemplate>
<asp:Label ID="lblUnitPrice" runat="server" Text='<%# Eval("UnitPrice")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Qty">
<ItemTemplate>
<asp:Label ID="lblQuantity" runat="server" Text='<%# Eval("Quantity")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Line Total">
<ItemTemplate>
<asp:Label ID="lblLineTotal" runat="server" Text="0"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Add Item" ConvertEmptyStringToNull="False">
<ItemTemplate>
<asp:Button ID="ButtonAdd" runat="server" CssClass="btn btn-primary" Text="Add" OnClick="AddItem" CausesValidation="False" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
</div>
</div>
</div>
<div class="card-footer">
<div class="pull-right">
<asp:Button ID="btnSubmit" runat="server" CausesValidation="false" TabIndex="2" CssClass="btn btn-primary" Text="Print KOT" />
<asp:Button ID="Button1" runat="server" CausesValidation="false" TabIndex="2" CssClass="btn btn-primary" Text="Print Final Bill" />
<asp:Button ID="Button2" runat="server" CausesValidation="false" TabIndex="2" CssClass="btn btn-primary" Text="Complete Order" />
</div>
</div>
</div>
</div>
</ItemTemplate>
</asp:Repeater>
</div>
还有我的C#代码来获取商品详细信息:
protected void GetItemDetails(object sender, EventArgs e)
{
foreach(RepeaterItem rptrItems in rptrTables.Items)
{
GridView gvItems = (GridView)rptrTables.Items[0].FindControl("grdOrder");
foreach (GridViewRow row in gvItems.Rows)
{
DropDownList ddl = sender as DropDownList;
Control ctrl = row.FindControl("drpItemName") as DropDownList;
if (ctrl != null)
{
DropDownList ddl1 = (DropDownList)ctrl;
if (ddl.ClientID == ddl1.ClientID)
{
Label UnitPrice = row.FindControl("lblUnitPrice") as Label;
Label QTTY = row.FindControl("lblQuantity") as Label;
Label UPrice = row.FindControl("lblUnitPrice") as Label;
Label LINETOTAL = row.FindControl("lblLineTotal") as Label;
SqlConnection conn = new SqlConnection(constring);
conn.Open();
if (ctrl != null)
{
if ((ddl1.ID == ddl.ID) && (ddl1.SelectedIndex == ddl.SelectedIndex))
{
string str = "select * from ItemMaster where ItemName='" + ddl1.SelectedItem.ToString() + "'";
SqlCommand com = new SqlCommand(str, conn);
SqlDataReader reader = com.ExecuteReader();
while (reader.Read())
{
UnitPrice.Text = reader["UnitPrice"].ToString();
QTTY.Text = reader["Quantity"].ToString(); ;
decimal totamt = Convert.ToDecimal(QTTY.Text) * Convert.ToDecimal(UnitPrice.Text);
}
reader.Close();
conn.Close();
}
else
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "swal", "swal('Item already selected, you can increase the quantity instead!', 'warning');", true);
}
}
}
}
}
}
}
答案 0 :(得分:0)
您的代码有问题。您总是从中继器控件中选择第一项,
GridView gvItems =(GridView)rptrTables.Items [0] .FindControl(“ grdOrder”);
更改代码以从foreach循环中获取项目,因此您的代码将为
GridView gvItems = (GridView)rptrItems.FindControl("grdOrder");
每次尝试使用rptrItems而不是转发器控件的第一项。
希望这会有所帮助。
