两个datagridviews:从一个发送信息到另一个 [英] Two datagridviews: Sending information from one to the other

问题描述

我有两个DataGridView:DataGridView2，DataGridView3.

我在DataGridView2的名为"Column1"的列中具有复选框.

我希望能够在DataGridView2中选择多个行，然后单击和按钮，DataGridView3将仅包含复选框行.

到目前为止，这是转移"按钮中的内容:

I have two DataGridView''s: DataGridView2, DataGridView3.

I have checkboxes in DataGridView2 in a column named "Column1".

I want to be able to select multiple rows in DataGridView2 and click and button and DataGridView3 would contain only the checkboxed rows.

This is what I have so far in the "Transfer" button:

dataGridView3.Rows.Clear();
            string x = string.Empty;
            for (int ii = 0; ii <= dataGridView2.Rows.Count - 1; ii++)
            {

                DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)dataGridView2.Rows[ii].Cells["Column1"];



                //buttonCell.Enabled = !(Boolean)checkCell.Value;



                //Displays the status value of the check box


                if (dataGridView2.Rows[ii].Cells["Column1"].Value == null || dataGridView2.Rows[ii].Cells["Column1"].Value.ToString() == "" || Convert.ToBoolean(dataGridView2.Rows[ii].Cells["Column1"].Value) == false)
                { }
                else
                {

                    if (dataGridView2.Rows[ii].Cells[0].Value != null)
                    { dataGridView3.Rows.Add(null,dataGridView2.Rows[ii].Cells[1].Value.ToString()); }

                    if (dataGridView2.Rows[ii].Cells[0].Value != null)
                    { dataGridView3.Rows[dataGridView3.Rows.Count + 1].Cells[1].Value = dataGridView2.Rows[ii].Cells[2].Value.ToString(); }

                    //if (dataGridView2.Rows[ii].Cells[0].Value != null || dataGridView2.Rows[ii].Cells[0].Value != "")
                    //{ dataGridView3.Rows.Add(dataGridView2.Rows[ii].Cells[0].Value.ToString()); }



                        //dataGridView3.Rows[ii].Cells[3].Value = dataGridView2.Rows[ii].Cells[3].Value.ToString();

                }
