Adding Cart in the Grid ?..

Question

Hi All,

 

I want to add the additional qty on my Dishcart of grid. Whenever I am clicking the addup button ., it should be Incremented by 1. How can do it. Can anyone guide me? Thanking you 

 

 

Sample code : 

 

protected void grdCart_RowCommand(object sender, GridViewCommandEventArgs e)

{

if (e.CommandName == "Qty")

{

for (int i = 0; i < grdCart.Rows.Count; i++)

{

TextBox Tb = (TextBox)grdCart.Rows[i].FindControl("txtEditCount");

QtyCount = Convert.ToInt32(Tb.Text);

QtyCount += 1;

DishCart_DataTable.Rows[i]["Count"] = QtyCount;

DishCart_DataTable.Rows[i]["Total"] = QtyCount * Convert.ToDecimal(DishCart_DataTable.Rows[i]["Price"]);

// Loading Grid..

grdCart.DataSource = DishCart_DataTable;

grdCart.DataBind();

}

}

}

 

This code has some issue. when click the add up button its added but when I select some other dish. Already selected items getting incremented by that should not happen. I Want to update the qty on the particular row on in grid.
