How to add a database into DataGridView?

Data query using DataTable storage.

For example the DataTable dt; dt object data exists

DataGirdView.DataSource=dt;

This put the data there is a DataGridView.

 

Data DataPropertyName need to column names in the database of a column in the Columns in the same complete the binding.

For example, do not show the class, you need to change the name to Shift (that is, the column names in the database).

When displayed, do not show how the order Edit Columns in?

 DataGirdView.AutoGenerateColumns = false;

Sequence can be made properly.

DataGridView DataTable is not only acceptable but also can receive it accepts a List object.

Increase in number.

int coun = grdData.RowCount;
for (int i = 0; i < coun - 1; i++)
{
grdData.Rows[i].Cells["RowID"].Value = i + 1;//引号中为列名
}

 The data in a column in the DataTable modified to want

For example: in the database is displayed to show empty EMPTY similar.

 for (int j = 0; j < dt.Rows.Count; j++)
            {
                if (dt.Rows.Count > 0)
                {
                    if (dt.Rows[j]["Ref_Status"].ToString().Equals(""))
                    {
                        strRefStatus = "EMPTY";
                    }
                    else
                    {
                        strRefStatus = dt.Rows[j]["Ref_Status"].ToString();
                    }
                    if (strRefStatus != "FULL")
                    {
                        strStatus = "";
                        if (strRefStatus == "EMPTY")

Class is used to define a target as a received data, and the class contained in the received required properties. To add an object to a List. GridTable accepted List.

List data may be selectively receiving portion by, in addition to the data in the List will be screened for display of the information satisfies the condition portion.

Screening List Information

 if (cboLine.Text != "ALL" && cboSO.Text != "ALL" && cboStatus.Text == "ALL")
            {
                list = list.Where(a => a.Line.Contains(cboLine.Text) && a.SO.Contains(cboSO.Text)).ToList();

Where a screening method using List, comprising screening according to the condition of the drop-down box, may be a plurality of single.

List Gets a value for each row

For example to obtain the status of each line, it will change.

            for (int i = 0; i < coun; i++)
