解决方案
请将您的页面加载代码放入！ispostback。
ex：
protected void Page_Load（object sender，EventArgs e）
{
if（！IsPostBack）
{
Recentinternship（）;
}
}
你正在做什么onrowdatabound =GridView2_RowDataBound显示代码
rowdatabound事件逐行将数据插入gridview，你的分页不工作可能不是geting值。
.aspx code
<asp:GridView ID="GridView2" runat="server" GridLines="None"
onrowdatabound="GridView2_RowDataBound" align="center"
PageSize="4" onpageindexchanging="GridView2_PageIndexChanging" ShowHeaderWhenEmpty="true" AllowPaging="true" >
<AlternatingRowStyle BackColor="White" />
<RowStyle BackColor="#CCCCCC" />
</asp:GridView>
.cs code
protected void Page_Load(object sender, EventArgs e)
{
Recentinternship();
}
protected void Recentinternship()
{
SqlConnection con = new SqlConnection("Data Source=jayraj-pc\\sqlexpress;Initial Catalog=Internship;Integrated Security=True;Pooling=False");
con.Open();
string str = "select B.CompanyLogo as ' ',A.Title,A.InternshipStartDate,A.ApplicationDeadline,A.Duration,A.InternshipCity,A.Category,A.Stipend,A.InternshipID,A.Degree,A.Branch,A.CompanyID,A.Title,A.CompanyName from Internship AS A INNER JOIN Companies AS B ON A.CompanyID=B.CompanyID ";
SqlCommand cmd = new SqlCommand(str, con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
SqlDataReader dr = cmd.ExecuteReader();
GridView2.DataSource = dr;
GridView2.DataBind();
//GridView2.BottomPagerRow.Visible = true;
dr.Close();
con.Close();
}
protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
string str = " Category :" + e.Row.Cells[6].Text + "<br/>Duration :" + e.Row.Cells[4].Text + "<br/>InternshipCity :" + e.Row.Cells[5].Text + "<br/>Stipend :" + e.Row.Cells[7].Text + "<br/>InternshipStartDate :" + e.Row.Cells[2].Text + "<br/>ApplicationDeadline :" + e.Row.Cells[3].Text + "<br/>Required Degree :" + e.Row.Cells[9].Text + "<br/>Required Branch :" + e.Row.Cells[10].Text;
e.Row.Cells[1].Text = str;
//e.Row.Cells[1].Visible = false;
//e.Row.Cells[2].Visible = false;
e.Row.Cells[3].Visible = false;
e.Row.Cells[4].Visible = false;
e.Row.Cells[5].Visible = false;
e.Row.Cells[6].Visible = false;
e.Row.Cells[7].Visible = false;
e.Row.Cells[8].Visible = false;
e.Row.Cells[9].Visible = false;
e.Row.Cells[10].Visible = false;
e.Row.Cells[11].Visible = false;
e.Row.Cells[12].Visible = false;
e.Row.Cells[13].Visible = false;
if (GridView2.Rows.Count > 0)
{
GridView2.HeaderRow.Cells[0].Text = " ";
GridView2.HeaderRow.Cells[1].Text = " ";
GridView2.HeaderRow.Cells[2].Text = " ";
}
Image img = new Image();
img.ID = "abc";
img.ImageUrl = e.Row.Cells[0].Text;
e.Row.Cells[0].Controls.Add(img);
Button btn = new Button();
//btn.Text = "preview";
e.Row.Cells[2].Controls.Add(btn);
btn.CausesValidation = false;
btn.Text = "View and Apply";
if (Session.Count > 0)
{
btn.PostBackUrl = "Apply_internship.aspx?InternshipID=" + e.Row.Cells[8].Text + "&CompanyID=" + e.Row.Cells[11].Text + "&Title=" + e.Row.Cells[12].Text + "&CompanyName=" + e.Row.Cells[13].Text + "";
}
else
{
btn.PostBackUrl = "Apply_login.aspx";
}
}
protected void GridView2_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView2.PageIndex = e.NewPageIndex;
Recentinternship();
} 解决方案
hi,
please put your page load code in !ispostback.
ex :
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Recentinternship();
}
}
what you are doing on onrowdatabound="GridView2_RowDataBound" show code
rowdatabound event insert data into gridview row by row and your paging not working might its not geting value.
