Question

我在RadGrid编辑表单中有三个控件我的目标是将textbox1和textbox2相乘，并使用javascript

在TextBox3上显示结果

 function multiply() {
                         var TextBox1 = document.getElementById('TextBox1').value;
                         var TextBox2 = document.getElementById('TextBox2').value;
                         var result = parseInt(TextBox1) * parseInt(TextBox2);
                         if (!isNaN(result)) {
                             document.getElementById('TextBox3').value = result;
                         }
                     }

当我将代码用于控件外侧radgrid或radgrid编辑模板时，代码工作正常，但如何在RadGRid编辑表单上实现相同的代码

如果没有弄错，这就是你想要的？
是在EditMode =“EditForms”

<asp:ScriptManager ID="sm" runat="server"></asp:ScriptManager>
    <telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource" AutoGenerateColumns="false" OnItemCommand="RadGrid1_ItemCommand">
        <MasterTableView EditMode="EditForms">
            <EditFormSettings>
                <EditColumn Visible="false"></EditColumn>
            </EditFormSettings>
            <Columns>
                <telerik:GridTemplateColumn>
                    <ItemTemplate><asp:Label ID="lbl" runat="server" Text='<%# Eval("A") %>'></asp:Label></ItemTemplate>
                    <EditItemTemplate>
                        <asp:TextBox ID="txt1" runat="server" onkeyup="calculate();"></asp:TextBox> * 
                        <asp:TextBox ID="txt2" runat="server" onkeyup="calculate();"></asp:TextBox> =
                        <asp:TextBox ID="txt3" runat="server" Text='<%# Eval("A") %>'></asp:TextBox>
                    </EditItemTemplate>
                </telerik:GridTemplateColumn>
                <telerik:GridTemplateColumn>
                    <ItemTemplate><asp:LinkButton ID="lbtnEdit" runat="server" CommandName="Edit" Text="Edit"></asp:LinkButton></ItemTemplate>
                    <EditItemTemplate>

        <script type="text/javascript">

            function calculate() {
