You need to rebind the gridview in SearchButton_Click.

My childhood story -
I have a user control with one gridview control on it and the code behind for the user control is shown below
protected void Page_Load(object sender, EventArgs e)
{
gvResults.DataSource = theSource;
gvResults.DataBind();
}private List theSource; public List<string> TheSource { get { return theSource; } set { theSource = value; } }When I pass value to the control on the page load I works fine with the data being displayed on the grid as shown by the code below
protected void Page_Load(object sender, EventArgs e)
{
string[] myData = {"10", "20", "30"};
DataPager1.TheSource = myData.ToList();
}But when I try to do the same thing by clicking a button, the page shows no data
protected void SearchButton_Click(object sender, EventArgs e)
{
string[] myData = {"10", "20", "30"};
DataPager1.TheSource = myData.ToList();
}DataPager1 is the usercontrol ID. Any help will be appreciated.
I tried it myself, but not success at all with that. I can provide you alternate way. Just change your
SearchButton_Clickevent with following snippets.protected void SearchButton_Click(object sender, EventArgs e)
{
string[] myData = {"10", "20", "30"};
//DataPager1.TheSource = myData.ToList();
GridView gview = (GridView)DataPager1.FindControl("gvResults");
gview.DataSource = myData;
gview.DataBind();

Thanks Hiren for your response, what you posted will work but the only problem is that I need to manipulate the data on the user control, not on the web page itself. So I just wanted a way to pass data from the web page unto the user control and then manipulate it from there. Funny thing is that it works on the Page_Load event but doesn't on the button_click event!

Instead binding the data on Page_Load event of the user control, I created a method for doing the same thing and it worked. I think the reason is because the Page_Load even of the user control fires and then that of the page fires too which happens automatically, so in order to force a bind, I had to create a simple method like this
public void BindData() { gvResults.DataSource = TheSource; gvResults.DataBind(); }and then on web page, I just did this
protected void SearchButton\_Click(object sender, EventArgs e) { DataPager1.TheSource = myData.ToList(); DataPager1.BindData(); }Now that works, but now it looks as though the gridview events from the user control like "OnRowCreated" ain't firing. Oh well, at least I've got one bit working :)

Yes, That's the way. Thanks for sharing solution.
