How to add a button with custom command name and perform an operation?

ASPX PAGE

<asp:GridView ID="GridView1" runat="server" OnRowCommand="FireRowCommand" DataKeyNames="AutoId">
<Columns>
<asp:TemplateField HeaderText="Mark as Deleted">
<ItemTemplate>
<asp:LinkButton ID="btnDeleted" runat="server" CommandArgument='<%# Eval("AutoId") %>'
CommandName="MarkAsDeleted" Text="Mark As Deleted" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Mark as Archived">
<ItemTemplate>
<asp:LinkButton ID="btnArchived" runat="server" CommandArgument='<%# Eval("AutoId") %>'
CommandName="MarkAsArchived" Text="Mark as Archived" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
 

In the above code snippet, we have a GridView where we have kept two TemplateField with LinkButtons. The first button CommandName is “MarkAsDeleted” and the second button CommandName is “MarkAsArchived”.

CODE BEHIND

string _connStr = ConfigurationManager.ConnectionStrings["ConnStr"].ConnectionString;
 
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
GetData();
}
}
 
private void GetData()
{
DataTable table = new DataTable();
// get the connection
using (SqlConnection conn = new SqlConnection(_connStr))
{
// write the sql statement to execute
string sql = "SELECT AutoId, FirstName, LastName, Age, Active FROM PersonalDetail ORDER By AutoId";
// instantiate the command object to fire
using (SqlCommand cmd = new SqlCommand(sql, conn))
{
// get the adapter object and attach the command object to it
using (SqlDataAdapter ad = new SqlDataAdapter(cmd))
{
// fire Fill method to fetch the data and fill into DataTable
ad.Fill(table);
}
}
}
// specify the data source for the GridView
GridView1.DataSource = table;
// bind the data now
GridView1.DataBind();
}
 
protected void FireRowCommand(object sender, GridViewCommandEventArgs e)
{
string command = e.CommandName;
string autoId = e.CommandArgument.ToString();
switch (command)
{
case "MarkAsDeleted":
Response.Write("<b>Mark As Deleted for " + autoId + " </b> button clicked");
break;
case "MarkAsArchived":
Response.Write("<b>Mark As Archived for " + autoId + " </b> button clicked");
break;
}
}
 

When these "MarkAsArchived",“MarkAsDeleted” buttons are clicked the OnRowCommand event fires that execute the FireRowCommand sever side method. In this method, we have retrieved the CommandName and CommandArguments that we had set for buttons in the GridView. The CommandName differs from button to button and based on its value we have written text under the switch statement.

OUTPUT

Note: The same can be achived using normal button as well instead of LinkButton.
