Question

嗨我有一个gridview，每行都有一个按钮，打开一个模态，它可以工作。出于测试目的，我给了我的imagebutton相同的commandName，看它是否也会打开模态。不幸的是它没有......

经过一些调试后我发现imagebutton没有返回索引（行号）所以我的详细模式无法显示，因为我收到错误：

An exception of type 'System.FormatException' occurred in mscorlib.dll but was not handled in user code

Additional information: Input string was not in a correct format.

我想知道如何使用imagebutton传递行的索引号。

我在下面提供了我的代码：

使用find获取asp ajax模态弹出窗口的对象

，ID为

var modalobj=$find("<%=modalid.ClientID%>");
modalobj.show();

与Behaviourid：

var modalobj=$find("Behaviourid");
modalobj.show();

使用您的代码：

sb.Append(@"<script type='text/javascript'>");
sb.Append("$find('detailModal').show();");
sb.Append(@"</script>");
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "DetailModalScript", sb.ToString(), false);

Finding modal popup with Behaviourid

Imagebutton没有给出gridview的索引，因此模态不能打开
