C# control ListView usage

Add title

Show grid

Add data to the table

Customize other properties

End

Add Title
Add a ListView component in the Winfrom interface, then click the arrow in the upper right corner, click Edit Column

Add the title below, then click OK

At this time, the ListView is still blank, and these titles cannot be displayed. Select Details in the view here

It will be as shown in the figure below, although the title is out, the content is indeed a white version, I still think the DataGridView component is easy to use at this time

Show grid
At this point, the table is just blank, you canSet in the properties panel to display the grid, as shown below

At this time, as shown in the figure below, the effect comes out, but there are still shortcomings in it

Add data to the table
What should I do if no data is added?Copied directly from the Internet, as follows:

private void Button_Test_Click(object sender, EventArgs e)
{
//Data update, UI is temporarily suspended until EndUpdate draws controls, which can effectively avoid flickering and greatly improve loading speed
this.listView1.BeginUpdate();
//Add 5 rows of data
for (int i = 0; i < 5; i++)
{
ListViewItem lvi = new ListViewItem();
lvi.SubItems.Add("column 1,th" + i + "row");
lvi.SubItems.Add("column 2, th" + i + "row");
lvi.SubItems.Add("column 3, th" + i + "row");
lvi.SubItems.Add("4th column, "+i + "row");
lvi.SubItems.Add("5th column," + i + "row");
this.listView1.Items.Add(lvi);
}
//End data processing, the UI interface is drawn at one time.
this.listView1.EndUpdate();
}
After running, let's see the effect, what? There is no data in the first line serial number,

Check the breakpoint, the ListViewItem array index 0 is actually empty

I searched for information, but I still found a solution:

private void Button_Test_Click(object sender, EventArgs e)
{
//Data update, UI is temporarily suspended until EndUpdate draws controls, which can effectively avoid flickering and greatly improve loading speed
listView1.BeginUpdate();
//Add 5row data
for (int i = 0; i < 5; i++)
{
int column = i + 1;
ListViewItem lvi = listView1.Items.Add("column 1,th" + column + "row");
lvi.SubItems.Add("column 2," + column + "row");
lvi.SubItems.Add("column 3," + column + "row");
lvi.SubItems.Add("Column 4," + column + "row");
lvi.SubItems.Add("Column 5," + column + "row");
}
//EndData processing, the UI interface is drawn at one time.
listView1.EndUpdate();
}
This kind of writing looks very painful, and there is no other way for the time being

Now the effect is achieved, but what if I want to change the properties of one of the cells?

Customize other properties
Example 1: Change the background color and font color

private void Button_Test_Click(object sender, EventArgs e)
{
//Data update, UI is temporarily suspended until EndUpdate draws controls, which can effectively avoid flickering and greatly improve loading speed
listView1.BeginUpdate();
//Add 5row data
for (int i = 0; i < 5; i++)
{
int column = i + 1;
ListViewItem lvi = listView1.Items.Add("column 1,th" + column + "row");
lvi.SubItems.Add("column 2," + column + "row");
lvi.SubItems.Add("column 3," + column + "row");
lvi.SubItems.Add("column 4," + column + "row");
lvi.SubItems.Add("column 5," + column + "row");
if (column % 2 ==0)
{
lvi.BackColor = Color.Red;
lvi.ForeColor = Color.White;
}
else
{
lvi.BackColor = Color.Green;
lvi.ForeColor = Color.Black;
}
}
//End data processing, UI interface is one-timedraw.
listView1.EndUpdate();
}
Effect:

Other attributes will not be demonstrated, and the writing is similar.
