If anyone knows how, please, help write such sorting code on the dataGridView column so that everything is adequate with double digits. That is, the values ​​in the cell are always in the format string and when sorting it cannot perceive 10 as "ten", it perceives as "one and zero". I tried to convert the cell into a numeric format via Convert, TryParse, Parse and tipeoff, but to no avail. Is it really so difficult in C #? This is what sorting now looks like:

void SortDataViewByColumn(DataGridView dataGridView, string nameColumn) // Подпрограмма сортировки по интересу { dataGridView.Sort(dataGridView.Columns[nameColumn], ListSortDirection.Descending); }

And her call when you press the button

  private void сортироватьЧастныеТаблицыToolStripMenuItem_Click(object sender, EventArgs e) { SortDataViewByColumn(dataGridView2, "dataGridViewTextBoxColumn8"); SortDataViewByColumn(dataGridView3, "dataGridViewTextBoxColumn2"); SortDataViewByColumn(dataGridView4, "dataGridViewTextBoxColumn4"); SortDataViewByColumn(dataGridView5, "dataGridViewTextBoxColumn10"); SortDataViewByColumn(dataGridView6, "dataGridViewTextBoxColumn6"); }

Please, help please, my hands have already dropped - my knowledge of the language is absolutely not enough for this.

You can work with DataGridView manually, but this is extremely inconvenient. Use the DataSource property to bind the displayed data to the DataGridView , and place the data in a separate collection and sort it as you like by events from the DataGridView or other form elements. A collection with data can be any, but there are some nuances in the behavior of the DataGridView when working with different collections. For a simple display, List<YourDataItems> is enough; if you need the ability to add lines at no extra cost, then it is better to use the BindingList<<YourDataItems> . Well, there is always the option to make a full-format databinding, but this already depends on the task.
