Binding Shopping Cart Check box Session onto another Gridview

Binding Shopping Cart Check box Session onto another Gridview - c#

I am new to asp.net and I am trying to make a shopping cart. I have a shop set up that has a list of school supplies and a check box next to each one with a "Add to Cart" button on the bottom. I want to store only the checked items into a session and call it to another gridview on my Shopping Cart page. For some reason my gridview on my Shopping cart page is not appearing.

protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
DataTable dt = (DataTable)Session["ShoppingCart"];
gvProductsList.DataSource = dt;
gvProductsList.DataBind();
}
}

Try this:-
List<GridViewRow> gridcheckedrows = gvProducts.Rows.Cast<GridViewRow>().
Where(x => (x.FindControl("cbAdd") as CheckBox)
.Checked == true).ToList();
I used below custom data to bind the grid gvProducts
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
DataTable dt = new DataTable();
dt.Columns.Add("Id");
dt.Columns.Add("Name");
dt.Columns.Add("Price");
DataRow dr = dt.NewRow();
dr[0] = "1";
dr[1] = "Sharique";
dr[2] = "120";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[0] = "2";
dr[1] = "Ansari";
dr[2] = "100";
dt.Rows.Add(dr);
gvProducts.DataSource = dt;
gvProducts.DataBind();
}
}
use this to bind you grid gvProductsList
List<GridViewRow> gridcheckedrows = gvProducts.Rows.Cast<GridViewRow>().Where(x => (x.FindControl("cbAdd") as CheckBox).Checked == true).ToList();
DataTable dt = new DataTable();
dt.Columns.Add("Id");
dt.Columns.Add("Name");
dt.Columns.Add("Price");
dt.Columns.Add("Count");
dt.Columns.Add("Quantity");
foreach (GridViewRow gvr in gridcheckedrows)
{
DataRow dr = dt.NewRow();
dr["Id"] = gvr.Cells[0].Text;
dr["Name"] = gvr.Cells[1].Text;
dr["Price"] = gvr.Cells[2].Text;
dr["Count"] = "1";
dr["Quantity"] = "2";
dt.Rows.Add(dr);
}
gvProductsList.DataSource = dt;
gvProductsList.DataBind();
and for grid gvProductsList use below html
<asp:GridView ID="gvProductsList" runat="server">
<Columns>
<asp:TemplateField HeaderText="ID">
<ItemTemplate>
<asp:Label ID="lblID" runat="server" Text='<%# Bind("ID")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Name">

<asp:TemplateField HeaderText="Price">

Cell Text Always &nbsp:

I want to display the text of a specific cell in a textbox whenever I select a row from my gridview but whenever i do this "&nbsp" is the only text that I get even though the cell is not empty. Data on the gridview is bound from my database and I made a function where all the data from my database will be bound on my gridview. Below is the code that I'm using.
textbox1.Text = myGridView.SelectedRow.Cells[3].Text;

Function that binds Data
private void PopulateData()
{
DataTable dataTable = new DataTable();
using (SqlConnection connection = new SqlConnection(WebConfigurationManager.ConnectionStrings["TestCS"].ConnectionString))
{
string path = "PopulateSQL.txt";
StringBuilder sb = new StringBuilder();
using (StreamReader sr = new StreamReader(path))
{
while (sr.Peek() >= 0)
{
sb.Append(sr.ReadLine());
}
string sql = sb.ToString();
using (SqlCommand cmd = new SqlCommand(sql, connection))
{
using (SqlDataAdapter dataAdapt = new SqlDataAdapter(cmd))
{
dataAdapt.Fill(dataTable);
ViewState["NormalGrid"] = dataTable;
}
}
}
}
if (dataTable.Rows.Count > 0)
{
TraineeGrid.DataSource = dataTable;
TraineeGrid.DataBind();
}
else
{
//Displays 'No Data Found' to gridview if there are no data in table
dataTable.Rows.Add(dataTable.NewRow());
TraineeGrid.DataSource = dataTable;
TraineeGrid.DataBind();
TraineeGrid.Rows[0].Cells.Clear();
TraineeGrid.Rows[0].Cells.Add(new TableCell());
TraineeGrid.Rows[0].Cells[0].ColumnSpan = dataTable.Columns.Count;
TraineeGrid.Rows[0].Cells[0].Text = "No Data Found";
TraineeGrid.Rows[0].Cells[0].HorizontalAlign = HorizontalAlign.Center;
}
}

You can use this: textbox1.Text = Server.HtmlDecode(row.Cells[1].Text.Trim());
In OnSelectedIndexChanged :
protected void OnSelectedIndexChanged1(object sender, EventArgs e)
{
//Get the selected row
GridViewRow row = GridView1.SelectedRow;
if (row != null)
{
// With
// TextBox1.Text = (row.FindControl("lblLocalTime") as Label).Text;
// Without
TextBox1.Text = Server.HtmlDecode(row.Cells[1].Text.Trim());
}
}
Complete Markup:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"

<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="150" />
<asp:BoundField DataField="City" HeaderText="City" ItemStyle-Width="150" />
</Columns>

I've already found a solution. The problem is Im using TemplateField instead of BoundField that's why I cant use .Cells[] to get the specific cell that I wanted to get. However, if you are using TemplateField you can use .FindControl() and put in the ID of the label where your binding of data happens (ex. Text ='<%# Eval("FirstName") %>'). You can see that I put label on ItemTemplate to call it's ID.

Edit Gridview Row ASP.net

Struggling to edit a Gridview Row. Once I hit edit the gridview disappears, I guess because I only bind the grid on !IsPostBack - although the tutorial tells me to do it this way.
I have tried rebinding on postback which lets me edit the gridview but keeps the default values - not the new values.
Any help appreciated.
if (!IsPostBack)
{
if (Session["Order_ID"] != null)
{
showgrid(int.Parse(Session["Order_ID"].ToString()));
}
}
public void showgrid(int Order_ID)
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["MyDbConn"].ToString());
string sqlstring = "Removed - is working";
SqlCommand cmd = new SqlCommand(sqlstring, conn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
conn.Close();
if (ds.Tables[0].Rows.Count > 0)
{
gv_ExistingAds.DataSource = ds;
gv_ExistingAds.DataBind();
}
}
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
gv_ExistingAds.EditIndex = e.NewEditIndex;
showgrid(int.Parse(Session["Order_ID"].ToString()));
}
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
Label lb = (Label)gv_ExistingAds.Rows[e.RowIndex].FindControl("Label3");
TextBox tx1 = (TextBox)gv_ExistingAds.Rows[e.RowIndex].FindControl("TextBox3");
string tx11 = tx1.Text;
gv_ExistingAds.EditIndex = -1;

Use code when gridview edit,
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView gridView1= (GridView)sender;
// Change the row state
gridView1.Rows[e.NewEditIndex].RowState = DataControlRowState.Edit;
}
For Update(this is sample code)
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridView gv = (GridView)sender;
GridViewRow gvr = (GridViewRow)gv.Rows[e.RowIndex];
TextBox TxtRejectReason= (TextBox)gvr.FindControl("TxtRejectReason");
string s = TxtRejectReason.Text;
GridView.EditIndex = -1;
GridView.DataBind();
}

Trying to Add Insert Row to Footer in GridView ASP.net

I'm trying to give the user the ability to create a new record from the footer row and my event handler doesn't seem to be working... or maybe I'm going at this all wrong.
The insert button that I enabled in the gridview doesn't work either...checkout the site at http://aisched.engr.oregonstate.edu/admin/courses.aspx
Here is my code in front and behind:
public partial class admin_courses : System.Web.UI.Page
{
public Table table;
ListDictionary listValues = new ListDictionary();
TextBox textBox1 = new TextBox(); //Name
TextBox textBox2 = new TextBox(); //CR
TextBox textBox3 = new TextBox(); //CourseNum
TextBox textBox4 = new TextBox(); //Dept
protected void Page_Init()
{
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.Footer) return; //Escape if not footer
textBox1.ID = "name";
textBox1.Width = 250;
textBox2.ID = "credit_hours";
textBox2.Width = 25;
textBox3.ID = "dept";
textBox3.Width = 30;
textBox4.ID = "class";
textBox4.Width = 25;
LinkButton add = new LinkButton();
add.ID = "add";
add.Text = "Add course";
add.CommandName = "add";
add.Click += new EventHandler(add_Click);
e.Row.Cells[1].Controls.Add(textBox1);
e.Row.Cells[2].Controls.Add(textBox2);
e.Row.Cells[3].Controls.Add(textBox3);
e.Row.Cells[4].Controls.Add(textBox4);
e.Row.Cells[5].Controls.Add(add);
}
public void add_Click(object sender, EventArgs e)
{
Response.Write("you Clicked Add Course!");
if (textBox1.Text != null && textBox2.Text != null && textBox3.Text != null && textBox4.Text != null) {
listValues.Add("name", textBox1.Text);
listValues.Add("credit_hours", textBox2.Text);
listValues.Add("dept", textBox4.Text); //For Visual
listValues.Add("class", textBox3.Text);
}
LinqDataSource1.Insert(listValues);
Response.Redirect("~/admin/courses.aspx");
}

I couldn't make it work without writing code manually to do the Insert. Handling the AddLinkButton_Click event in the Page_Load event by examining the EventTarget hidden field to see if it ends with 'addlinkbutton' feels quite wrong, but it works.

A Sample pseudo code which can add from grid view footer, Initially data's are saved under View State, Using button click event to check the ViewState and insert the new data to the table.
