How to delete a row from GridView without affecting the Database

I am populating a Gridview using a form with the help of AJAX.
I want to add a delete button to each row and whendelet button is clicked that row should be deleted from GridView (not hidden).
Here is my aspx code:
<asp:Content ID="Content2" ContentPlaceHolderID="Nav" runat="server">
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="server">
<table>
<tr>
<td class="auto-style1">
<asp:Label ID="LabelFirstName" runat="server" Text="First Name"></asp:Label>
</td>
<td>
<asp:TextBox ID="TextBoxFirstName" runat="server" CssClass="auto-style2"></asp:TextBox>
</td>
</tr>
<tr>
<td class="auto-style1">
<asp:Label ID="LabelLastName" runat="server" Text="Last Name"></asp:Label>
</td>
<td>
<asp:TextBox ID="TextBoxLastName" runat="server"></asp:TextBox>
</td>
</tr>
</table>
<br /><br />
<asp:Button ID="ButtonSearch" runat="server" Text="Search" CssClass="auto-style3" Width="93px" OnClick="ButtonSearch_Click" />
<br /><br />
<asp:Label ID="LabelNoRows" runat="server" Text="Sorry, we couldn't find any data with this Name." Visible="false" ForeColor="Red"></asp:Label>
<asp:Panel ID="PanelAbsenceInfo" runat="server" Visible="false">
<table>

<td class="auto-style4">

<td>
<asp:Label ID="LabelGetFirstName" runat="server"></asp:Label>

</table>
<br /><br />
<asp:GridView ID="GridViewViewAllRequests" runat="server" AutoGenerateColumns="False" DataKeyNames="id"
OnRowCommand="GridViewViewAllRequests_RowCommand">
<Columns>
<asp:BoundField DataField="scrap" Visible ="false" />

<br /><br />
</asp:Content>
And here is my cs code:
public partial class AbsenceRequestMonitor : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void ButtonSearch_Click(object sender, EventArgs e)
{
DoAction();
}
public Boolean ScraptheRequest(int id, bool action)
{
bool success = false;
success = DBOperation.ScrapAbsencedate(id, action);
return success;
}
protected void GridViewViewAllRequests_RowCommand(object sender, GridViewCommandEventArgs e)
{
//Determine the RowIndex of the Row whose Button was clicked.
int id = Convert.ToInt32(e.CommandArgument);
//Get the value of column from the DataKeys using the RowIndex.
// int id = Convert.ToInt32(GridViewViewAllRequests.DataKeys[rowIndex].Values[0]);
if(e.CommandName == "Scrap")
{
ScraptheRequest(id, true);
}
else if(e.CommandName == "Undo")
{
ScraptheRequest(id, false);
}
DoAction();
UpdatePanelInfo.Update();
}
public void DoAction()
{
string firstName = null;
string lastName = null;
firstName = TextBoxFirstName.Text.ToString();
lastName = TextBoxLastName.Text.ToString();
double PdCount = 0;
double OtherCount = 0;
if (firstName != null && lastName != null)
{
//gets student data from the Student Form
List<AbsenceMonitorData> l_studentAbsenceInfo = DBOperation.getStudentAbsenceInfo(firstName, lastName);
AbsenceMonitorData studentAbsenceInfo = l_studentAbsenceInfo.FirstOrDefault();
PdCount += l_studentAbsenceInfo.Where(x => x.reason == "Personal Day").Where(y => y.isApproved == true).Where(z => z.scrap == false).Select(a => a.daysMissed).Sum();
OtherCount += l_studentAbsenceInfo.Where(x => x.reason != "Personal Day").Where(y => y.isApproved == true).Where(z => z.scrap == false).Select(a => a.daysMissed).Sum();
GridViewViewAllRequests.DataSource = l_studentAbsenceInfo;
GridViewViewAllRequests.DataBind();
if (l_studentAbsenceInfo.Count > 0)
{
LabelGetPersonal.Text = PdCount.ToString();
LabelGetOther.Text = OtherCount.ToString();
LabelgetTotaldays.Text = (PdCount + OtherCount).ToString();
LabelGetFirstName.Text = studentAbsenceInfo.firstName.ToString();
LabelGetLname.Text = studentAbsenceInfo.lastname.ToString();
LabelGetEmail.Text = studentAbsenceInfo.studentEmail.ToString();
PanelAbsenceInfo.Visible = true;
LabelNoRows.Visible = false;
}
else
{
LabelNoRows.Visible = true;
}
}
}
}
Right now i was using the Scrap/Undo button which i want to replace it with a Delete button.
Also when i delete the row the count should be affected. (ie. Personal Days Approved, Other Days Approved and Total Days Approved)
The image shows that when i type the name and hit search, GridView is obtained.
I need to be able to delete rows from that gridview.

Change table row text and bgcolor on a listview value asp.net C

I have a listview and I am trying to change the text color and background color depending on the value of "callswaiting". This is written in C#.
I am trying to accomplish this:
If(Eval("availableAgents") < 1); Then
; If(Eval("callsWaiting" > 2) ,Then );
{
tblSheet.Style.Add("color", "black");
tblSheet.Style.Add("background-color", "red");
}
Else;
{
tblSheet.Style.Add("color", "black");
tblSheet.Style.Add("background-color", "orange");
}
End If;
Else;
{
tblSheet.Style.Add("color", "white");
tblSheet.Style.Add("background-color", "green");
}
End If;

.NET ListView not populating on control selection

I have a ListView in .NET that is hooked up to various CRUD methods, the select method that accepts a value doesn't seem to be working. The Data Source is supposed to be taking the value from a drop down list control, taking the selected value. when I do the configure data source method in visual studio, I select this method for my select operation:
EntReqList_byID(Int32 programID), returns List<EntranceRequirementInfo>
Then when I define parameters in the next part of the wizard, I pick control as a parameter source, with the control ID set to CertificateList, which shows the programID as the parameter from CertificateList.SelectedValue.
When I run the page, and select an item from the CertificateList, and click "Show Program", all my data is pulled except for that in the list view. My code is as follows:
The top of my page:
Please select the program credential type:
<asp:DropDownList ID="InitialCredential" runat="server" AutoPostBack="True" OnSelectedIndexChanged="InitialCredential_SelectedIndexChanged">
<asp:ListItem>[Select]</asp:ListItem>
<asp:ListItem>Certificate</asp:ListItem>
<asp:ListItem>Diploma</asp:ListItem>
<asp:ListItem>Degree</asp:ListItem>
</asp:DropDownList>
</p>
<p>
Please select a program:

Is there something I am missing to make it get the programID, and populate the data?

Why DropDownList value is missing during postback?

I have a DropDownList whose value is missing when I trigger post-back. Here my aspx, JavaScript and C# code.
Javascript:

if (event.keyCode == 13) {
document.getElementById('tbfrompalletno').focus();
}
}
function tblocenter(event) {
if (event.keyCode == 13) {
__doPostBack('__Page', 'save');
}
}

Returning multiple rows in asp:Table from SQL DataSet

My question is how can I duplicate the second < tr > in the < table > if there are more than one record returned in the code behind query... Any pointers or tips are appreciated...

There are a few ways to do this. Look into the Repeater control if you want to use a table like this, or look into using a GridView and binding your result set to that. (It is possible to have a dropdowns and textboxes inside of a GridView.)
Also, make sure your code validates ProjectID.Text to avoid any potential SQL injection issues!
