pass a value to same page on clicking a button in asp.net

[priravi]

Hi

i'm new to asp .. and .net environment.. the task is on clicking a button i want the same page to be posted back with an additional flag variable..and then i want to check this variable and based on it i have to follow a different path

so i tried in the onclick event of the image button to call the same page

e.g default.aspx?'&flagvalue=1'

and in the codebehind on page load event if i try to get the value

using request.querystring , it always seems to be null ami missing something here

or is there any better way than this


thanks in advance

hi

<input type=hidden id="favouriteflag" value ="">

<td border=0>
<input type="image" align ="absbottom" src="images/favourite.gif" alt="My favourites" border=0 style="cursor:hand;" onclick=" 'cb_datalist.aspx?Title=Concept Bank&amp;profile=' +'<%=Session["s_repositoryId"]%>'+ '&amp;workspaceid='+workspace + '&amp;parentid=0'+ '&amp;favouriteflag=1'" >
</td>


and in the code behind in pageload event,i gave
if(Request.QueryString["favouriteflag"]!=null)
{
Session["favflag"]= Request.QueryString["favouriteflag"];

}

I just want to show the text before of paging, is there any property to set the text before the page index.

hi friend,
i think there is a space between Concept and Bank
remove the space and try

You could do some of the above or you could find the values in a simple onclick. HTH.
