Hi,

I apologise if I am getting this all wrong, but why are you not trying to use the page load event? I mean you are at the end setting the querystring value to a Server side control, So why not execute it on the page load event.

Hope this helps to solve your problem.

Good Luck [yes]

thanx for reply 

in C# i tried both way as...

<asp:TextBox ID="TextBox1" runat="server" Text='<%# Request.QueryString["CategoryID"](1) %>'></asp:TextBox>

<asp:TextBox ID="TextBox1" runat="server" Text='<%# Request.QueryString["CategoryID"][1] %>'></asp:TextBox> 

but its not working./.

User-908924113 posted

Have you passed the CategoryID from the previous page as CategoryID in the querystring? If so then it should work in your case itself ..without the (1) because you are passing the ID itself. values(1) implies the 1st querystring value.

Answer 12

User-1509636757 posted

Have you passed the CategoryID from the previous page as CategoryID in the querystring?

 

Yes.. i am passing the categoryID from previous page, as i can access in javascript...as

    function test()
    {
        var var1 = '<%= Request.QueryString["CategoryID"] %>';
        alert(var1);
    }

it gives me alert with correct categoryID... but somehow its not working in ASPX tag./. 

Answer 13

User-908924113 posted

Response.Redirect("yourpage.aspx?somevariable=something&ContractID="+txtContractID.Text); is required in the previous page to access the querystring value in this page...

 

Answer 14

User-908924113 posted

Ohoh... Are you loading this page? I mean as a popup? Because probably the page is being rendered before you set the value

and if you can use javascript the best thing would be to find the control with window.document.GetElementByID('Textbox1').value='<%= Request.QueryString["CategoryID"] %>'>

note the use of valua and not Value or Text

 i am posting my complete code...

on first page Default.aspx; i am passing categoryID... on a button click

    protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Redirect("Default2.aspx?CategoryID=10");       
    }

 

and on second page Default2.aspx, i try to access QueryString in ASPX page as...

<head runat="server">
    <title>Untitled Page</title>
    <script type="text/javascript" language="javascript">
    function test()
    {
        var var1 = '<%= Request.QueryString["CategoryID"] %>';
        alert(var1);
    }
   
    </script>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <asp:TextBox ID="TextBox1" runat="server" Text='<%# Request.QueryString["CategoryID"] %>'></asp:TextBox>           
        </div>
    </form>
</body>
</html>

 

actually the purpose to do this is... i am having an adrotator on second page... and from first page i will get the categoryID and based on that categoryID; i have to give the AdvertisementFile (xml file) to this adtotator... so i write as...

<asp:AdRotator AdvertisementFile='<%# String.Format("~/skins/Skin_15/ProductAds-{0}.xml", Request.QueryString["CategoryID"]) %>' ID="ProductAdRotator" runat="server" BorderWidth="1" BorderColor="LightGray" BorderStyle ="Solid" Width = "" Height="" />

u can use folowing  javascript it will return valye of querystring

function Query()

{

var is_input = document.URL.lastIndexOf('=');

var addr_str = document.URL.substring(is_input+1, document.URL.length);

var mid = document.URL.lastIndexOf

alert( addr_str);

return addr_str;

}

User200962433 posted

Hi Kaushal,

I think I have some sort of a solution. See, I thnk your main problem was that you wanted the AdRotator object to have the value of QueryString. So, I have some sort of a solution

In you SecondPage i.e Default2.aspx add the following jaavscript code

function fnLoadAd()

{

var AdvertObj = document.getElementById("ProductAdRotator");

AdvertObj.AdvertisementFile = <yourfilepath> + '<%= Request.QueryString["CategoryID"] %>' + ".xml";

alert(AdvertObj.AdvertisementFile)

}

Execute this function on the body onload event and I think it will solve your problem. I have tried it on my machine and it worked fine.

Hope this helps to solve your problem

Good Luck [yes]
