[英]dynamic GridView with dynamic Number Of Row
How I can create dynamic GridView with dynamic number of row When click on button 单击按钮时如何创建具有动态行数的动态GridView
and put in one column DropDownList . 并放入一列DropDownList。
GridView is a databound control. GridView是一个数据绑定控件。 It means that it shows what is in the datasource.
这意味着它显示了数据源中的内容。 To add a row, you need to add an item to the datasource and re-bind the gridview.
要添加一行,您需要向数据源添加一个项目并重新绑定gridview。 You can't add rows to the gridview directly.
您不能直接向gridview添加行。
Your question is pretty brief, but if if i think i understand what you want to do, you could try this: 您的问题很简短,但是如果我认为我了解您想要做什么,则可以尝试以下操作:
in the codebehind of your button 在按钮后面的代码中
List<string> ThisIsYourList = new List<string>();
Gridview1.DataSource = ThisIsYourList;
Gridview1.DataBind();
if you want to add a dropdownlist to every row, you need to add an itemtemplate to your gridview like this: 如果要向每行添加一个下拉列表,则需要向网格视图中添加一个项目模板,如下所示:
<asp:TemplateField>
<ItemTemplate>
<asp:DropDownList ID="DropDownList1" runat="server"/>
</ItemTemplate>
</asp:TemplateField>
You add this itemtemplate anywhere between the tags of your gridview. 您可以在gridview的标签之间的任何位置添加此itemtemplate。
