<body>
<form id="form1" runat="server">
<div>
 <asp:DropDownList ID="DropDownList2" runat="server" Width="165px">
<asp:ListItem>[Select Group]</asp:ListItem>
<asp:ListItem>A+ </asp:ListItem>
<asp:ListItem>B+ </asp:ListItem>
<asp:ListItem>AB+ </asp:ListItem>
<asp:ListItem>O+ </asp:ListItem>
<asp:ListItem>A-</asp:ListItem>
<asp:ListItem>B-</asp:ListItem>
<asp:ListItem>AB-</asp:ListItem>
<asp:ListItem>O-</asp:ListItem>
</asp:DropDownList>
<asp:DropDownList ID="DropDownList3" runat="server" Width="167px">
<asp:ListItem>Jammu Kashmir</asp:ListItem>
</asp:DropDownList>
<asp:DropDownList ID="DropDownList1" runat="server" Width="167px">
<asp:ListItem>Jammu</asp:ListItem>
<asp:ListItem>Srinagar</asp:ListItem>
</asp:DropDownList>

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Search" Width="88px" /><br />
<br />
 </div>
</form>
</body>

code behind is like this

C#

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class search : System.Web.UI.Page
{

protected void Page_Load(object sender, EventArgs e)
{

}
protected void Button1_Click(object sender, EventArgs e)
{

Response.Redirect ("search_donor.aspx?bg=" + DropDownList2.SelectedItem.Text + "&st=" + DropDownList3.SelectedItem.Text + "&city=" + DropDownList1.SelectedItem.Text);

}
}

but I am not getting the results in the grid view where I pass these querystrings

i think this is because of A+,A-,AB+ when we pass it in query string it creates a problem

please tell me way out.

You need to elaborate more on this:
but I am not getting the results in the grid view where I pass these querystrings

i think this is because of A+,A-,AB+ when we pass it in query string it creates a problem
I doubt this as + or - should not hamper with query string.

Solution 1

For your requirement just replace the '+' with any other character. Check the sample

C#

Response.Redirect("search_donor.aspx?bg=" + DropDownList2.SelectedItem.Text.Replace('+', '/') + "&st=" + DropDownList3.SelectedItem.Text + "&city=" + DropDownList1.SelectedItem.Text);

//Retrieve the value like
string str=Request.QueryString["bg"].ToString().Replace('/','+');
