推荐答案
要解决您的问题，让我们使用带有c＃的javascript：
在html代码中，在 head 标记中键入以下javascript。
当您按下文本框中的键时，此代码将触发。
javascript代码将找到一个文本框元素，保存值和在C＃代码隐藏中触发一个按钮。
Hi,
To solve your problem, let's using javascript with c#:
In html code type the javascript below in your head tag.
This code will fire when you press the key in the textbox.
The javascript code will find a text box element, save the value and fire a button in the C # code-behind.
<script type="text/javascript">
function KeyPressText(id_row, text, button)
{
document.getElementById(text).value = id_row;
document.getElementById(button).click();
}
</script>
在gridview下面添加两个元素，1文本框和1个按钮。此组件将隐藏在您的页面中。
Below your gridview, add two elements, 1 textbox and 1 button. This component will stay hidden in your page.
<asp:TextBox ID="txtIndexRow" runat="server" style="visibility:hidden;"></asp:TextBox>
<asp:Button ID="btnOcIndex" runat="server" Text="FindRow" OnClick="btnOcIndex_Click" style="visibility:hidden;"/>
为您的隐藏按钮创建 OnClick 事件，并在您阅读的地方添加代码网格的索引。
Create the OnClick event for your hidden button and add the code where you read the index of the grid.
protected void btnOcIndex_Click(object sender, EventArgs e)
{
string indexrow = this.txtIndexRow.Text;
}
在你的网格中添加 OnRowCreated 事件并添加以下代码。 />
此代码在文本框中添加属性 onkeypress ，为网格中的每一行调用javascript函数。
In your gridvew add the OnRowCreated event and add the code below.
This code add the attribute onkeypress in the textbox, calling the javascript function, for each line in the grid.
protected void grd_result_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex > -1)
{
((TextBox)e.Row.FindControl("TextBox1")).Attributes["onkeypress"] = "KeyPressText('" + e.Row.RowIndex.ToString() + "', '" + txtIndexRow.ClientID + "', '" + this.btnOcIndex.ClientID + "');";
}
}
这里！完整的代码。

}
</script>
</head>

<asp:GridView ID="grd_result" OnRowCreated="grd_result_RowCreated">

<asp:Button ID="btnOcIndex" runat="server" Text="FindRow" OnClick="btnOcIndex_Click" style="visibility:hidden;"/>
</div>

}
}
protected void btnOcIndex_Click(object sender, EventArgs e)
{
string indexrow = this.txtIndexRow.Text;
}
