如何处理网格视图中存在的文本框的按键事件 [英] how to handle on key press event of a textbox present inside a grid view

问题描述

嗨专家，



我有一个名为grditemDetails的网格视图

，因为有3个文本框，即txtItemQty，txtItemPrice，txtItemAmmount
如果用户在txtItemQty字段中输入任何内容，将填写选择商品价格列的


自动填写txtItemAmmount而不使用 textchanged 事件



有什么办法吗？

推荐答案

在模板字段内添加文本框写入

Add textbox inside template field write

<asp:textbox id="txt1" onkeypress="return changeColoronfocus(this);" xmlns:asp="#unknown"></asp:textbox>

以下是调用a的示例处理按键事件的JavaScript方法。我还包括下面的JavaScript方法。



GridView专栏内：

Here is example of calling a JavaScript method that handles key press event. I also included the JavaScript method, below.

Inside of the GridView column:

<asp:TemplateField HeaderText="Doses Received" FooterStyle-Width="70px" HeaderStyle-Wrap="true" ItemStyle-Width="70px">
                                            <ItemTemplate>
                                                <asp:TextBox ID="txtDosesReceived" runat="server" onkeypress="return NoCommaAllowed(event);" MaxLength="10" Width="70px"

                                                    Text='<%# Bind("DosesReceived") %>'></asp:TextBox>
                                            </ItemTemplate>
                                            <HeaderStyle HorizontalAlign="Center" />
                                        </asp:TemplateField>

JS方法：



< pre lang =cs>函数NoCommaAllowed（evt）{

var charCode =（evt.which）？ evt.which：event.keyCode

return！（charCode == 44）;

}< / pre>

JS Method:

<pre lang="cs">function NoCommaAllowed(evt) {
var charCode = (evt.which) ? evt.which : event.keyCode
return !(charCode == 44);
}</pre>
