在代码中设置gridview数据源时未生成列 [英] Columns not being generated when gridview datasource is set in code

问题描述

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="true">
</asp:GridView>

GridView1.AutoGenerateColumns = true;
GridView1.DataSource = db.Snippets.ToList();
GridView1.DataBind();
//shows us that we have no columns
giveJavascriptMessage(GridView1.Columns.Count.ToString());

//I want to be able to hide specific columns at the moment this returns an index out              of range
GridView1.Columns[0].visible=false;

我使用实体框架模型来填充gridview。



当我运行此代码时，它会创建网格视图并使用表填充它，但是当我尝试访问网格视图中的列时，没有giveJavascriptMessage（GridView1.Columns.Count.ToString（））;

返回0



为什么没有列被创建，尽管所有数据都显示在页面上？

如何创建列？

Im using an entity framework model to populate the gridview.

When I run this code it creates the grid-view and populates it with the table but when I try to access the columns in the grid view there are none "giveJavascriptMessage(GridView1.Columns.Count.ToString());"
returns 0

Why are no columns being created although all data is shown on the page?
How can I get the columns to be created?
