[英]filter data by a column in datagrid using combobox
I'm trying to filter by the stats column, which contains 3 types of data "valid", "out of use" and "request purchase", but I'm not able to filter by the three, when I try to filter only by one it works, but the three together don't filters none.if anyone can help me what is the problem with the code我正在尝试按统计信息列进行过滤,其中包含 3 种类型的数据“有效”、“未使用”和“请求购买”,但是当我尝试仅过滤时,我无法按这三种类型进行过滤一个有效,但三个一起不能过滤 none。如果有人能帮我,代码有什么问题
code:代码:
private void combo_SelectedIndexChanged(object sender, EventArgs e)
{
if (combo.SelectedIndex == 1) ;
DataView pp = (dtgridreagentes.DataSource as DataTable).DefaultView;
pp.RowFilter = string.Format("Stats = '{0}'", "Válido");
if (combo.SelectedIndex == 2) ;
DataView rr = (dtgridreagentes.DataSource as DataTable).DefaultView;
rr.RowFilter = string.Format("Stats = '{0}'", "Fora de uso");
if (combo.SelectedIndex == 3) ;
DataView tt = (dtgridreagentes.DataSource as DataTable).DefaultView;
tt.RowFilter = string.Format("Stats = '{0}'", "Solicitar compra");
}
There is an obvious bug in your code.您的代码中存在明显的错误。
There is no {} after your if, you should write your code in a code block. if 后面没有 {},您应该将代码写在代码块中。
If you run your code, only the last 2 lines of code will work.如果你运行你的代码,只有最后两行代码可以工作。
Correctly modify this question:正确修改此题:
if (combo.SelectedIndex == 1)
{
DataView pp = (dtgridreagentes.DataSource as DataTable).DefaultView;
pp.RowFilter = string.Format("Stats = '{0}'", "Válido");
}
