I created a search page(search.aspx) to get the column name the user want to display and pass them as query string to detail list page(detail.aspx).

In the detail list page, I created a gridview to display those columns. At first, when I created the gridview, I invisible them.

<asp:content id="Content1" contentplaceholderid="phMain" runat="Server" xmlns:asp="#unknown">
<asp:gridview id="GridView1" runat="server" autogeneratecolumns="False">
DataKeyNames="autoid" DataSourceID="SqlDataSource1">
<columns> <asp:boundfield datafield="autoid" headertext="ID" insertvisible="False">
ReadOnly="True" SortExpression="autoid" />
<asp:boundfield datafield="name" headertext="Name" sortexpression="name" visible="False">
<asp:boundfield datafield="description" headertext="Description" visible="False">
SortExpression="description" />
<asp:boundfield datafield="typeid" headertext="Type" visible="False">
SortExpression="typeid" />
<asp:boundfield datafield="daterequested" headertext="Date Requested" visible="False">
SortExpression="daterequested" DataFormatString='{0:dd/MMM/yy}"' />
<asp:boundfield datafield="requiredby" headertext="Required By" visible="False">
SortExpression="requiredby" DataFormatString='{0:dd/MMM/yy}"' />
<asp:boundfield datafield="lastupdated" headertext="Last Updated" visible="False">
SortExpression="lastupdated" DataFormatString='{0:dd/MMM/yy}"'/>
<asp:boundfield datafield="lastcomment" headertext="Comment" visible="False">
SortExpression="lastcomment" />
<asp:boundfield datafield="lastupdateby" headertext="Last Update By" visible="False">
SortExpression="lastupdateby" />

<asp:sqldatasource id="SqlDataSource1" runat="server">
ConnectionString="<%$ ConnectionStrings:ConnectionString1 %>"
SelectCommand="SELECT * FROM [tbldetail]

Then, in the Page_Load, I want to visible particular column which pass the string from page before (search.aspx)

protected void Page_Load(object sender, EventArgs e)
{

String selectcolumn = this.Request.QueryString["Selected"];

string[] columnID = commaStringToArray(selectcolumn);

// how to find the datafield of each column and visible them.

}

private string[] commaStringToArray(string strComma)
{
string [] strArray;
strArray = strComma.Split(new char[] {','});
return strArray;
}

In the web, they were all searching the headertext. But, I want to do the datafield.

So, why don't you use it as a server side control?

Another option is to store the value of the textbox somewhere and than again populate it after the postback.

hi Manas Bhardwaj,

with the help of the following code...

Request.Params["ComapanyName"];

how to populated back this value to the html textbox without using runat="server"...

Use request object to get value of your html textbox
and populates the control on every postbacks

Hi Friends ,

I have problem regarding creation bin folder in ASP.NET 2.0 which includes .DLL and assemblies for deploying the website.Whenever , I am compiling and running my asp.net 2.0 application , it won't create bin folder in the application.And I want to create bin folder automatically , as like in .NET versio 1.1

Please, suggest me that , what's the solution of this problem?

thanks in advance.

That is generally known as Precompilation[^].

In simple words VS does not create ddl for WebSite
you will have to explicitly create the dll by precompilation process

DropDownList1.Items.Add(new ListItem(Convert.ToString(DropDownList1.Items.Count + 1), Convert.ToString(DropDownList1.Items.Count + 1)));

If you have to bind dropdownlist from database then bind it after you add new task.

If my post helps you kindly save my time by voting my post.

So, from what I can find (and there is very little on the subject that I can locate) this control cannot be used to interface with a regular database like the login control can be. It seems to be hard wired to want\need to use the Membership system that is part of ASP.NET .

Is this true? Can anyone either conform or deny this? If I CAN use it with a regular old Access database someone please please please point me in the direction of some decent docs on the subject.

Thanks!

Oh, and before anyone comes back to me about using Access, please don't Smile | :)

It's not my fault I am being made to use this poor excuse for a database engine to back an ASP.NET web site. Smile | :)

I have a If statement that i use to return an integer that will mean Success or Failure , now am testing for that integer in my ASP.NET 2.0 Page lke this

 if (Res == 1)
       {


Response.Write(@"<script> alert('You have Successfully Registred');</script>");

           Response.Redirect("login.aspx", false);
       }
       else
       {

Response.Write(@"<script> alert('Invalid Data has been Entered');</script>");

Now if the value is 1, then it should Display the Message and after the Message has been Clicked it should move to the login Page. Now my Problem is that it moves to the Login Page without a Alert Message being Displayed And the send Alert for invalid Entry, will not show anythingm, there is a Warning sign on my Page at the Bootom left of my Page. What is wrong with my Javascript

Thanks

You can not send two responses to one request, so you can't both have a page containing the Javascript and a page for the redirect. When you do the redirect the current page (where you added the script) is scrapped, and a redirect page is sent instead. So the reason that the alert doesn't show up is that you removed it.

You either have to make the login page show the alert, or do the redirect using Javascript.

When you get a warning sign at the bottom of the page, there is an error message. Double click the warning sign to display the error message.

It's probably because you put the script in the wrong place in the page. You should not use Response.Write at all, unless you take over the responsability for the page completely and write out the entire page with Response.Write. If you use Response.Write to put the script in the page, you will write it before the actual html document, which will keep it from working properly.

Use the ClientScript.RegisterStartupScript method to add scripts to the page.

Despite everything, the person most likely to be fooling you next is yourself.

Page.RegisterStartupScript("hai", "alert('hai')")
the above display alert box

Thanks it works

You can do in follwoing way
if (Res == 1)
{
this.ClientScript.RegisterStartupScript(this.GetType(), "key", "myfunction();", true);
)

and in myfunction function just show the alert message and redirect user to Login Page
<script type="text/javascript">
function myfunction()
{
alert('You have Successfully Registred')

window.location.href='Login.aspx';

}
</script>
