早上好，我想知道你是否可以帮我在gridview上应用一些必要的逻辑。我有一个asp.net gridview，每列有几个控件，下拉列表，文本框，复选框等。基于dropdowlist更改我想要执行或修改同一行中的其他下拉列表。例如，这是当前的gridview：
<asp:GridView ID="gridScopeItem" runat="server" AllowPaging="True" DataKeyNames="ItemID" AutoGenerateColumns="False" OnPageIndexChanging="gridScopeItem_PageIndexChanging" OnRowCommand="gridScopeItem_RowCommand" OnSelectedIndexChanged="gridScopeItem_SelectedIndexChanged"
OnRowDataBound="gridScopeItem_RowDataBound" CssClass="Grid" AlternatingRowStyle-CssClass="alt" PagerStyle-CssClass="pgr" OnRowUpdating="gridScopeItem_RowUpdating" OnRowCancelingEdit="gridScopeItem_RowCancelingEdit" OnRowEditing="gridScopeItem_RowEditing" OnRowUpdated="gridScopeItem_RowUpdated" PageSize="1" Caption="Scope Items">
<AlternatingRowStyle CssClass="alt" />
<Columns>
<asp:BoundField DataField="ScopeItemId" HeaderText="ID" HeaderStyle-CssClass="hiddencol" ItemStyle-CssClass="hiddencol">

</Columns>
<PagerStyle CssClass="pgr" />
</asp:GridView>
逻辑1：如果列上的下拉列表＆＃34;结果＆＃34; （class：clsresult）改为＆＃39; Def＆＃39; （值2），我希望类clspercent（％Done）的下拉列表更改为0％并获得锁定。 逻辑2：如果相同的dorpdownlist结果变为＆＃39; Non Def＆＃39; （值3），因此同一行中的结果下拉列表仅包含可用项：＆＃39; 100％＆＃39;和＆＃39;部分SJO＆＃39;，其他人得到锁定或只是删除它们（仅在这一特定行），以及＆＃34;重新检查＆＃34;下拉列表将更改为值＆＃39;否＆＃39;。 对于这些逻辑，这就是我在jQuery上所做的：
$(function () {
// Find all of your drop downs within your Grid and initialize the enabled, disabled ones
$('#ContentPlaceHolder1_pGridScopeItems [id$=".clsresult"]').each(function () {
// Based on the selection, enable or disable certain elements
var $row = $(this).closest('tr');
// Check the percent field and enable/disabled and change the value
$row.find('[id$=".clspercent"]').prop('disabled', $(this).val() == "2");
// So in the second code line I change the value to 0 and change Re-Inspect to Yes
$row.find('[id$=".clspercent"]').val('0%', $(this).val() == "2"); $row.find('[id$=".clsreinspect"]').val('Yes', $(this).val() == "2");
});
// Whenever one of your DropDownLists is changed, perform the appropriate logic
$('#ContentPlaceHolder1_pGridScopeItems [id$=".clsresult"]').change(function () {
// Based on the selection, enable or disable certain elements
var $row = $(this).closest('tr');
// Check the percent and enable/disabled
$row.find('[id$=".clspercent"]').prop('disabled', $(this).val() == "2");
// Do the same thing for Reinspect field
$row.find('[id$=".clsreinspect"]').prop('disabled', $(this).val() == "2"); $row.find('[id$=".clsreinspect"]').val('Yes', $(this).val() == "2");
});
});
正如您所看到的，我使用母版页，这就是为什么元素ID更改为ContentPlaceHolder1_Name＃，而我更愿意使用该类来引用控件。最后，我在两个事件中应用逻辑，当下拉列表更改时以及页面加载时。我非常感谢以最佳方式或更好的做法实现这一目标的任何帮助。我想念第二个逻辑，第一个逻辑不正常。
