I created a fees form which is like this :

ASP.NET

<table><tbody><tr><td> Department ID </td></tr></tbody></table>
<asp:DropDownList ID= "DDLdpId" runat="server" >

<table><tbody><tr><td> Fees </td></tr></tbody></table>
<td> 
<asp:TextBox ID="txtFees" runat="server" >


<table><tbody><tr><td> Modifying </td></tr></tbody></table>

<asp:TextBox ID="txtModify_dt" runat="server" />

</td>

<table><tbody><tr><td>

<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" />

</td></tr></tbody></table>

<table><tbody><tr>
<td colspan="2" align="center">

<asp:GridView ID="grdShow" runat="server" AutoGenerateColumns="true" AllowSorting="true" AllowPaging="false"> 

</td>
</tr></tbody></table>

Then, whatever user enters it will be stored in database and will also be shown in Grid View Form which I did like this :

aspx.cs page

C#

protected void btnSubmit_Click(object sender, EventArgs e)
{
try
{

tblFee objtblFee = new tblFee();

objtblFee.dpID = Convert.ToDecimal(DDLdpId.SelectedValue);
objtblFee.amt = Convert.ToDecimal(txtFees.Text);
objtblFee.modify_dt = Convert.ToDateTime(txtModify_dt.Text);
objdbPollyClinicEntities.tblFees.AddObject(objtblFee);
objdbPollyClinicEntities.SaveChanges();

populateGrd();
lblMsg.Text = "Fee successfully entered.";
txtFees.Text = "";
txtModify_dt.Text = "";
}
catch (Exception ex)
{

lblMsg.Text = ex.Message;
}
}

private void populateGrd()
{
var lstFees = objdbPollyClinicEntities.tblFees.ToList();
grdShow.DataSource = lstFees; grdShow.DataBind();

}

Now I want to add delete button in this gridview so the user can also delete it.

Please can someone show me how to do this?? Please I need help.

    var id = buttonDelete.CommandArgument;

    var feeToRemove = objdbPollyClinicEntities.tblFees.Where(p => p.Id == id).FirstOrDefault();

    if (null != feeToRemove)
    {
        objdbPollyClinicEntities.tblFees.Remove(feeToRemove);
        objdbPollyClinicEntities.SaveChanges();
    }
}
