问题描述

与使用C#的Asp.net 3.5相关的问题

推荐答案

嗨Faiz，

您将无法直接从任何.net类中获取此信息，如果您使用任何第三方gridview或ajax，这将非常困难.但是，如果您尝试使用基本功能，您将能够做到这一点.

在keypress事件中捕获键，然后将所选行增加1.

Hi Faiz,

You won''t be able to get this directly from any of the .net class and it will be difficult if you are using any 3rd party gridview or ajax. But you will able to do so if you try with the basic.

in keypress event catch the key and then increment the selected row by 1.

TextBox1.Attributes.Add("OnKeyPress", "GetKeyPress()")

In the Default.ASPX Code page, I have

<script>

Function GetKeyPress()
{
    alert("you Pressed " & event.KeyCode;
}

</script>

现在，在此函数中，您可以使用类似这样的内容

now within this function you can use something like this

GridView gv = new GridView();
       GridViewRow r = gv.SelectedRow; // handel case when no row is selected
       // set the new focus to new row

       gv.SelectedRow.RowIndex = r.RowIndex + 1;

这可能现在就可以了，因为我还没有在VS上做到这一点.如果有任何问题，请尝试让我知道.

祝一切顺利！

this might now work as of now because i havent done this on VS .. please try and let me know in case of any issue.

All the best!!
