Blank column of the datagridview datagri. by default, the background color of the selected row is selected. In the datagridview, add the check box to change the check box status.

Example:

1. the blank column of the datagridview refers to that each row of the datagridview dview has a row header and cannot be bound to or operated on. I don't know if you have ever had a headache. I used to ignore it. Later, I found that the datagridview attribute panel has a rowheadersvisible attribute that sets whether the row header is displayed, set the value to false.

2. By default, the background color of the selected row of the datagridview is blue, which looks ugly. After the datagridview data is bound, the background color of the first row is blue by default, however, the first row is not selected. To solve this problem, a datagridviewcheckboxcolumn is added to the row. Whether the row is selected depends on whether the datagridviewcheckboxcolumn is selected, now, let's talk about the background color of the selected row. click the button on the Right of rowdefaultcellstyle in the datagridview attribute to open the cellstyle generator and change selectionbackcolor to the background color you want. do not set selectionbackcolor and selectionforecolor to the same value.

3. You can add a check box to the dview by specifying the columntype value of a column as the datagridviewcheckboxcolumn. As long as you have added a column, it is no stranger, but to change its check status, it took me half a day and now the problem has been solved. Let's look back, how can we use a simple word to describe it,

Private void maid (Object sender, maid E)
{// When any cell content in a row is clicked
If (maid [E. columnindex]. Name = "column0 ")
{
Datagridviewcheckboxcell dgcb = (datagridviewcheckboxcell) datagridview1.rows [E. rowindex]. cells ["column0"];
If (bool) dgcb. formattedvalue)
{
Dgcb. value = false;
}
Else
{
Dgcb. value = true;
}
}
}

OK. I just transferred to winform for development. I used to work on a website. I used vs2008. If not, please correct it.
