Thanks for your answer.

try

void GridPage(object sender, GridViewPageEventArgs e)

        {

            GridOut.PageIndex = e.NewPageIndex;


        }

try to update your method ,

void GridPage(object sender, GridViewPageEventArgs e)

        {

            GridOut.PageIndex = e.NewPageIndex;

            GridOut.DataBind();

        }

With following,

void GridPage(object sender, GridViewPageEventArgs e)

        {

            GridOut.PageIndex = e.NewPageIndex;

             GridOut.DataSource = YourData;

            GridOut.DataBind();  

        }

Thanks for your answer...

I tried but the problem is that my Colleciton "CollectionforGreadView" is not Accesible in GridPage method.

I get collection after button click event.

I made Collection public and implemented it but it is still disaper...

Please notcie that i also use masterpage.

Does it have somthing with that to do...

using masterpage doesn't matter. The basic idea is to repopulate your GridView with the updated data after you do the paging and then call DataBind().

protected void GetUser_Submit(object sender, EventArgs e)

 {

 CollectionforGreadView= getUser.GetUserAccount(ConnectAD); //Hier i get my my collection.

            GridOut.DataSource = CollectionforGreadView;
            Session("DataSource") = CollectionGreadView;

            GridOut.DataBind();

}

 

void GridPage(object sender, GridViewPageEventArgs e)

        {

            GridOut.PageIndex = e.NewPageIndex;
            DataSource = Session("DataSource");
            GridOut.DataSource = DataSource;
            GridOut.DataBind();

        }

Update your code with above code..Try it and give feedback...You have to use session variable to get the datasource after postback..

Mark my post as Answer if it solve your problem..
