DataGridView变量格式

Question

I have a DataGridView with data I extract from SQL Server . I never know how many records i'll have in it so I need the grid to be variable to the number of rows extracted.

Exemple :

• Picture 1 : What I have right now. 1 row was extracted so I have a big dark gray space where the could have been data.
• Picture 2 : What I want to have with only 1 row extracted. The grid resizes automaticly depending on the number of rows.
• Picture 3 : What I would like to have with many rows.

Also, I would like to remove the empty row that is always added too, adding a new row won't be an option.

Is that possible ?

Answer 1

You are looking for DataSet.Datatable.Rows.Count this will tell you the total rows returned from your Sql Server

Update this cannot be achieved by using the any properties of the DataGridView Control

Answer 2

You need to set the AutoSizeColumns properties:

datagridview.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;
datagridview.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.DisplayedCells);

Assuming you're filling the grid from a DataSet , you can use this to prevent empty rows from being added:

foreach (DataRow row in dataset.Tables[0].Rows)
{
      if (!string.IsNullOrWhiteSpace(row[0].ToString()))
      {
            //add row
      }
}
