Dynamically set DataKeyNames in gridview

Question

How can I set the value of a DataKeyNames gridview in C # code?

since my gridview is dynamically generated, I need to install it from a .cs file

Answer 1

Enter the code in the cs file, for example

Gridview d

protected void Page_Load(object sender, EventArgs e)

{
    d = new GridView();

    d.DataKeyNames = new string[] { "Column1", "Column2" };
    form1.Controls.Add(d);
}

Answer 2

You can set it like any other grid property:

myGrid.DataKeyNames = new string[] {"Id", "Name"};

This corresponds to the following declarative code:

<asp:GridView id="myGrid" DataKeyNames="Id,Name" ... />

Answer 3

- :

myGridView.DataKeyNames =new string[]{"PrimaryKeyId"} 

Answer 4

DataKeyNames GridView.

{YourGriViewID}.DataKeyNames = new string[] {"ColV", "Col"};
