datagridview cell = =“hallo” [英] datagridview cell to be ="hallo"

问题描述

if (dataGridView1.CurrentRow.Cells[0].Value.ToString() == "a")
              {
                  (dataGridView1.CurrentRow.Cells[1] as DataGridViewComboBoxCell).Items.Add("a1"); // populate combobox with items
                  //dataGridView1.CurrentRow.Cells[2].Value.ToString() == "Hallo"; // Here I try to set the text in  cell 3 to Hallo

              }

怎么办设置dgv cell [2] =你好？



试试这个

What to do to set dgv cell[2] ="Hallo" ?

Tryed this

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
  {
      if (dataGridView1.CurrentCell.Value !=null)
      if (dataGridView1.CurrentCell.Value.ToString()=="a")
      {

          (dataGridView1.CurrentRow.Cells[1] as DataGridViewComboBoxCell).Items.Clear();
          (dataGridView1.CurrentRow.Cells[1] as DataGridViewComboBoxCell).Items.Add("a1");
          dataGridView1.Rows[0].Cells[2].Value = "Hallo";

      }

然后我得到System.ArgumentException：DataGridViewComboBoxCell上的值无效

Then i got System.ArgumentException:Value on DataGridViewComboBoxCell is not valid

推荐答案

尝试更改此

Try changing this

dataGridView1.CurrentRow.Cells[2].Value.ToString() == "Hallo"; 
// Here I try to set the text in  cell 3 to Hallo

to

to

datagridview1.CurrentRow.Cells[2].Value = "Hello";

试试这个

datagridview1.Rows [currentrowindex] .Cells [2] .Text =你好





如果是在windows中试试它

datagridview1.Rows [currentrowindex] .Cells [2] .value =hello

try this
datagridview1.Rows[currentrowindex].Cells[2].Text="hello"


if it is in windows try it as
datagridview1.Rows[currentrowindex].Cells[2].value="hello"
