如何在客户端计算RadGrid单元格值？

Question

我有telerik RadGrid,它处于编辑模式.每个单元格都包含NumericTextBox.是否可以根据同一行中的其他单元格(在客户端)计算一个单元格.例如,如果我有一行包含价格和项目,我想在每次更改时计算总价格但在客户端,而不是去服务器端.RadGrid有可能吗？

感谢您的所有答案,但我在telerik论坛找到了解决方案.我会在这里粘贴解决方案,以防有人遇到同样的问题.

ASPX:

<Columns> 
    <rad:GridTemplateColumn UniqueName="Price" HeaderText="Price">
    <EditItemTemplate> 
        <radI:RadNumericTextBox ID="txtPrice" runat="server">  
        </radI:RadNumericTextBox> 
    </EditItemTemplate> 
    </rad:GridTemplateColumn> 
    <rad:GridTemplateColumn UniqueName="Quantity" HeaderText=" Number of Items">  
    <EditItemTemplate> 
        <radI:RadNumericTextBox ID="txtQuantity" runat="server">  
        </radI:RadNumericTextBox> 
    </EditItemTemplate> 
    </rad:GridTemplateColumn> 
    <rad:GridTemplateColumn UniqueName="TotalAmount" HeaderText="Total">
    <EditItemTemplate> 
        <radI:RadNumericTextBox ID="txtTotalAmount" runat="server">  
        </radI:RadNumericTextBox> 
    </EditItemTemplate> 
    </rad:GridTemplateColumn> 
</Columns>

C#

  protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)  
    {  

    if (e.Item is GridDataItem && e.Item.IsInEditMode)  
    {  
        GridDataItem item = (GridDataItem)e.Item;  
        RadNumericTextBox txtPrice= item.FindControl("txtPrice") as RadNumericTextBox;       // Get the textbox for column Price   
        RadNumericTextBox txtQuantity= item.FindControl("txtQuantity") as RadNumericTextBox;    // Get the textbox for column Quantity     
        RadNumericTextBox txtTotalAmount= item.FindControl("txtTotalAmount") as RadNumericTextBox; // Get the textbox for column "TotalAmount", if it is template as shown in aspx    

        txtPrice.Attributes.Add("onFocusout", "return calculate('" + txtPrice.ClientID + "','" + txtQuantity.ClientID + "','" + txtTotalAmount.ClientID + "')");  
        txtQuantity.Attributes.Add("onFocusout", "return calculate('" + txtPrice.ClientID + "','" + txtQuantity.ClientID + "','" + txtTotalAmount.ClientID + "')");  
        txtTotalAmount.Attributes.Add("onfocus", "return calculate('" + txtPrice.ClientID + "','" + txtQuantity.ClientID + "','" + txtTotalAmount.ClientID + "')");  
    }  
} 

JavaScript的:

<script type="text/javascript">  
function calculate(price, quantity, totalAmount)   
{  
    var text1 = $find(price); //I used Asp.net Ajax find method
    var text2 = $find(quantity);  
    var text3 = $find(totalAmount);  
    var total = text1.GetValue() * text2.GetValue();  
    text3.SetValue(total);  
}  
</script>
