如何在GridView中添加过滤器? [英] How to add filter in gridview?

问题描述

大家好，
我想在gridview.i中添加下拉过滤器，但用Google搜索了很多，但我得到的是所有这些都使用单个表或列是在代码本身中生成的.

在我的情况下，从下拉列表中选择表名称时表会更改.因此我无法打开自动生成的列.

例如.

输入表格名称:电影/用户

gridview包含:具有不同类别的电影列表或具有不同列的用户列表.

请帮我.

I want to add dropdown filter in gridview.i googled a lot but all i got is that all are using a single table or columns are generated in code itself.

in my case,tables are changed on selecting the table name from a dropdownlist.so i can not make auto-generated-column on.

您可以在aspx代码页中添加DropDown:

Hi ,

you can add DropDown in aspx code page:

<asp:dropdownlist id="DropDownList1" runat="server" xmlns:asp="#unknown">AutoPostBack="true" 
       onselectedindexchanged="DropDownList1_SelectedIndexChanged">
   </asp:dropdownlist>

Autopostback属性将其设为true.

在C#代码页

Autopostback attribute make it true.

at C# code page

protected void  DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    if (DropDownList1.SelectedItem != null )
    {
        string selectedtext = DropDownList1.SelectedItem.Text;
        string selectedValue = DropDownList1.SelectedItem.Value;

        // write your logic for bind gridview as per selected item.
    }
}

请让我知道这对您有帮助.
