Question

我通过C＃代码手动填充ASP.NET GridView并打开了分页。当用户从一个页面转到另一个页面时，列宽度相应地调整到屏幕上的内容。我希望无论用户在哪个页面上，GridView列都保持不变（最好将每个列设置为其特定列的最大字符长度）。有人可以建议最好的行动方案来实现这一目标。以下是我填充GridView的方法

    private void BindData(string sortExpression, string sortDirection)
    {


        db_set_connection_string.set_db_connnection_string(configuration_manager.GetConfigValue("DBSTRING.1"));
        db_set_connection_string.set_individual_global_variables(configuration_manager.GetConfigValue("DBSTRING.1"));

        sSQLResults = db_connector_mysql.execute_query_with_results_returned("SELECT * From city", false);


        //Dynamically create columns
        foreach (DataColumn column in sSQLResults.Columns)
        {
            //So we aren't getting duplicates, we need to check to see if it exists first
            if (DoesColumnExistInGridView(column.ColumnName) == false)
            {
                BoundField nameColumn = new BoundField();
                nameColumn.DataField = column.ColumnName;
                nameColumn.HeaderText = column.ColumnName;
                nameColumn.SortExpression = column.ColumnName;
                GridView1.Columns.Add(nameColumn);
            }
        }            


        this.GridView1.DataSource = sSQLResults;

        if (sortExpression != null)
        {
            sSQLResults.DefaultView.Sort = sortExpression + " " + sortDirection;
        }            
        this.GridView1.DataBind();
    }

有两种方法可以做到这一点。在动态添加列时定义宽度。

 //Dynamically create columns
    foreach (DataColumn column in sSQLResults.Columns)
    {
        //So we aren't getting duplicates, we need to check to see if it exists first
        if (DoesColumnExistInGridView(column.ColumnName) == false)
        {
            BoundField nameColumn = new BoundField();
            nameColumn.DataField = column.ColumnName;
            nameColumn.HeaderText = column.ColumnName;
            nameColumn.SortExpression = column.ColumnName;
            nameColumn.Width=1;
            GridView1.Columns.Add(nameColumn);
        }
    }

或者您可以在Gird View行数据绑定事件

中执行此操作

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e){
 e.Rows.Cell[1].width=1;}

保持GridView列宽相同
