模型弹出窗口中的Gridview

Question

我写了一个模型弹出窗口，它显示了一个gridview。 GridView加载和数据显示完美，现在我想选择一行，它应该将值传递给页面中的几个文本框，从中打开弹出窗口。

//default.aspx

    } 
} 

请朋友们帮我。

把你的文本框的UpdatePanel其UpdateMode属性设置为Always内：

<asp:UpdatePanel ID="upTextBoxes" runat="server" UpdateMode="Always"> 
    <ContentTemplate> 
     <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> 
     <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox> 
    </ContentTemplate> 
</asp:UpdatePanel> 

这样，当网格视图执行异步回你的文本框将被刷新。

编辑：如果你也想关闭模式弹出，做服务器端，当你更新你的文本框：

protected void gvsearch_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    if (e.CommandName == "Select") { 
     TextBox1.Text = e.CommandArgument.ToString(); 
     mdlPopup.Hide(); 
    } 
}
