Question

Parsing Multiple values and sending it in a query string

Answer 1

A:

<form>
  <input type="checkbox" name="check[]" value ="1"/>
  <input type="checkbox" name="check[]" value ="2"/>
  <input type="checkbox" name="check[]" value ="3"/>
  <input type="checkbox" name="check[]" value ="4"/>
</form>

When you try to retrieve the parameter 'check' you get an array of all the values that were selected.

EDIT: This link should help in retrieving the values in ASP.

this regular html what about asp.net, programmatically?

I have added a link to the solution, hope it helps (I am not a asp.net programmer so I can't give you the exact code myself)

that seems more of a question than an actual answer :(

Answer 2

A:

Try this:

<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;

<script runat="server">

    protected void Page_Load(object sender, EventArgs e)
    {
     if (!IsPostBack)
     {
      System.Collections.Generic.List<int> Values = new System.Collections.Generic.List<int> { 1, 2, 3, 4, 5, 6, 7 };
      grdTest.DataSource = Values;
      grdTest.DataBind();
     }
    }

    protected void btnSubmit_Click(object sender, EventArgs e)
    {
     HtmlInputCheckBox chkTest = null;
     string SelectedValues = "";
     foreach (GridViewRow row in grdTest.Rows)
     {
      chkTest = (HtmlInputCheckBox) row.FindControl("chkTest");
      if (chkTest != null && chkTest.Checked)
      {
       SelectedValues += (SelectedValues == "" ? chkTest.Value : ", " + chkTest.Value);
      }
     }

     litValues.Text = SelectedValues;
    }
</script>

<html xmlns="http://www.w3.org/1999/xhtml"&gt;
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
         <asp:GridView ID="grdTest" runat="server">
       <Columns>
        <asp:TemplateField>
         <ItemTemplate>
          <input id="chkTest" type="checkbox" name="chkTest" runat="server" 
          value="<%# (int)Container.DataItem %>" />
         </ItemTemplate>
        </asp:TemplateField>
       </Columns>
      </asp:GridView>

      <asp:Button ID="btnSubmit" runat="server" onclick="btnSubmit_Click" Text="Submit"  />
      <br />
      <asp:Literal ID="litValues" runat="server"></asp:Literal>
    </div>
    </form>
</body>
</html>

not exactly what i'm look for. the list is not programatically created in the code behind. Its grab from a database and placed in a gridview.

ferronrsmith 2009-07-16 13:39:08

thanks anyways for the help.

ferronrsmith 2009-07-16 13:39:41

I was just generating a list in the page load to have something to bind to. I think the same concept would apply if the list came from the database. Can you post some of of your code so we can see what you are working with?

Chris Mullins 2009-07-16 14:51:40

I fixed the issue, thanks anyways. Your code gave me some ideas
