根据选择填充gridview [英] Populate gridview according to selection

问题描述

大家好

我的列表框中有数据，如果我在列表框中选择一行，则将向网格视图加载一些信息.

现在，如果在列表框中选择了另一行，则将向gridview加载不同的信息.事情是我想覆盖gridview，每次选择一个选项时，然后在不删除先前信息的情况下加载网格

Hi guys

I have data in my listbox, if i select a row in listbox, a gridview is loaded with some information.

Now if another row is selected in a listbox, gridview is goin to be loaded with diffrent information. The thing is i want to overwrite the gridview, evry time i select an option,then the grid is loaded with out removing the previous information

how can i approach that??

推荐答案

使用List<yourobjecttype></yourobjecttype>存储数据并将其设置为datagridview的数据源

这样的东西

Use a List<yourobjecttype></yourobjecttype> to store the data and set this as the datasource of the datagridview

Something like this

// member vars
List<yourobjecttype> items = new List<yourobjecttype>();
DataGridView grid = new DataGridView();

// event handler for list item being changed
private void ListBoxIndexChanged(..)
{
   items.AppendRange(GetData());
   grid.DataSource = items;

}

private List<yourobjecttype> GetData()
{
    List<yourobjecttype> data = new List<yourobjecttype>();
    // retrieve data
    
    return data ;  
}</yourobjecttype></yourobjecttype></yourobjecttype></yourobjecttype></yourobjecttype>
