The Tag property of a control in C #

The Tag property is available in many of the control's properties, but how to use it. What is the meaning of tag's use?


Tag itself is the meaning of "label", as the name suggests, is to label the control.
When you have many controls with different type names in your project, you can put the controls on the same label, that is, set the control's tag value to the same value, such as hide, TLB, and so on, and then use a piece of code to do the following:


for (int i = 0; i < ToolStripMain.Items.Count; i++)
{
if (toolstripmain.items[i). Tag = null)
Continue
if (toolstripmain.items[i). Tag.tostring ()!= "TLB")
Continue
Found = false;
if (arr!= null)
{
for (int j = 0; J < arr. Length; J + +)
{
if (arr[j] = = null) continue;
if (arr[j). Btname.toupper () = = Toolstripmain.items[i]. Name.toupper (). ToUpper ())
{
Toolstripmain.items[i]. Enabled = Arr[j]. Enabled;
Toolstripmain.items[i]. Visible = Arr[j]. visuable;
Toolstripmain.items[i]. ToolTipText = Arr[j]. Btdescription;
Found = true;
Hasbuttonshowatleastonece = true;
Break
}
}
}
if (! Found) Toolstripmain.items[i]. Visible = false;
}




Tags are often used to hide controls so that they appear when they are needed.
The use of the Tag property, can be used to bulk manipulate the control, very convenient.
