Question

<asp:GridView ID="GVFeedType" runat="server" Style="margin-bottom: 6px" BorderColor="#BDBDBD"
    CssClass="center" Width="500px" AutoGenerateColumns="false">
    <EmptyDataTemplate>
        No Records found</EmptyDataTemplate>
    <Columns>
        <asp:BoundField HeaderText="SNo" DataField="SNo" ItemStyle-Width="50px" />
        <asp:BoundField HeaderText="Feed Type" DataField="FeedType" ItemStyle-Width="200px" />
        <asp:TemplateField HeaderText="Rate/Kg" ItemStyle-Width="80px" ItemStyle-HorizontalAlign="Center">
            <ItemTemplate>
                <asp:TextBox ID="txtrate" runat="server" Width="100px" OnTextChanged="txtrate_TextChanged"
                    AutoPostBack="true" />
                <asp:RequiredFieldValidator ID="RFVrecdate1" runat="server" ControlToValidate="txtrate"
                    Display="None" ErrorMessage="Must Enter Rate" ValidationGroup="duereport"></asp:RequiredFieldValidator>

            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField HeaderText="Rate/50 Kg" ItemStyle-Width="80px">
            <ItemTemplate>
                <asp:Label ID="lbl50kg" runat="server" />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

我试过这段代码..

protected void txtrate_TextChanged(object sender, EventArgs e)
{

    GridViewRow currentRow = (GridViewRow)(sender as TextBox).Parent.Parent;
    float rate = 0;
    float kgrate50 = 50;

    rate = Convert.ToSingle((sender as TextBox).Text.Trim());
    kgrate50 = rate * kgrate50;
    (currentRow.Cells[3].FindControl("lbl50kg") as Label).Text = kgrate50.ToString();
    GVFeedType.Rows[currentRow.RowIndex + 1].Cells[2].FindControl("txtrate").Focus();
}

此代码没问题，Tab不工作... 我有一个网格视图控件中的文本框，当我输入一些像2,3,4 ..然后它乘以50 ...它显示输出在标签控制..其中标签也在gridview ..如何可以我解决了..请帮帮我......

我会将CSs类添加到文本框

<asp:TextBox ID="txtrate" runat="server" CssClass="TextBoxToHandle" Width="100px" OnTextChanged="txtrate_TextChanged"
                    AutoPostBack="true" />

由于使用tab throw focusout事件，您需要订阅它

$(function(){
  $(".TextBoxToHandle").focusout(function(){
    //Do your code here this would be element which you focus left
  });
})

如何使用javascript乘以文本框值？
