I try to write data grid in aspx. In my database there is a column which name is ‘PROJECT_NAME’. I want these columns in my data grid, then I add second column (editbox) to add values every each of project. This is all in grid view, and I add button in form. When I press the button how can I understand which columns value belong which project?

I mean, for example

  1. Row value : A project 2 Column value : 50
  2. Row value : B project 2 Column value : 60
  3. Row value : C project 2 Column value : 70

I want to know when I press button 1. project value 50 how can ı understand this?

This is my aspx code :

    Inside of Button1_Click you need need to loop through all the rows in the GridView and do a FindControl on each row to get the label and textbox. From that you can determine what the PRJ_PROJECT_NAME and values in the textbox are.

    Here is an example:

    Default.aspx

    <asp:GridView ID="gvData" runat="server" AutoGenerateColumns="false">
  <Columns>
    <asp:TemplateField>
      <ItemTemplate>
        <asp:Label ID="lblLabel" runat="server" Text='<%# Bind("Number") %>' />
      </ItemTemplate>          
    </asp:TemplateField>
    <asp:TemplateField>
      <ItemTemplate>
        <asp:TextBox ID="txtData" runat="server" Text='<%# Bind("Value") %>' />
      </ItemTemplate>
    </asp:TemplateField>
  </Columns>
</asp:GridView>
<asp:Button ID="btnSubmit" runat="server" OnClick="btnSubmit_Click" Text="Submit" />

    Default.aspx.cs

    protected void Page_Load(object sender, EventArgs e)
{
  if (!IsPostBack)
  {
    // Create some fake data and bind it to the gridview
    var data = new List<TheData>();

    foreach(var num in Enumerable.Range(1, 4))
    {
      var newData = new TheData();

      newData.Number = num.ToString();
      newData.Value = num;

      data.Add(newData);
    }

    gvData.DataSource = data;
    gvData.DataBind();
  }
}

protected void btnSubmit_Click(object sender, EventArgs e)
{
  for (var index = 0; index < gvData.Rows.Count; ++index)
  {
    var row = gvData.Rows[index];
    var lblLabel = row.FindControl("lblLabel") as Label;
    var txtData = row.FindControl("txtData") as TextBox;

    //Here is where the values are grabbed, at this point you can do what you need to.
    var number = lblLabel.Text;
    var value = txtData.Text;
  }
}
