You can save your time using that, even you don't need post this question if you have searched..... Use perfect keywords while searching in search engines.

Anyway I'll give you answer this time. Here in that page the OP solved the issue himself.

hi, thank you for all. i sorted out the issue. There are lots of problems related to this. if u created the Reports in 2005 and deployed in Report server 2008, you must have use Report viewer 8.0 or higher in your application.
And my issue was related to the credential. when i disable the report service credential class. the report starts to working fine.
Thanks for all.

Sql Membership / Login works local but not on production server

Hi All,

I have created a basic login site, right now just has a login and forgetpassword page.
The site works perfectly locally but on publishing when I navigate to forgotpassword page
after typing the username and click submit I get the following error "We were unable to access your information. Please try again. "
Also when I am trying to login I get the error"Invalid Username Or Password".

Why does it work locally and not on the production server?

Here is my web config file, I am unable to figure this out. Have done a lot of research and would appreciate your help.

Problem with a drpdownlist in a datalist

Nafiseh Salmani2-Apr-11 8:32

2-Apr-11 8:32

I have some problems with a dropdownlist which is in a datalist. the dropdownlist is created statically and has only 4 items from 1 to 4, and it is in each row. when I get the dropdownlist selectedindex all of them just return the default value 0 even if user select another items!! Cry | :((

I use the following code to access the dropdownlist and the selectedindex

DropDownList drp= dstQuestions.Items[i].FindControl("DrpAnswer")as DropDownList ;
int answer = drp.SelectedIndex + 1;

(dstQuestions is the name of the DataList.)

answer always return 1 !! what is the problem?!

Does your dropdown list has enable Postback. By default its false with DropdownList. So all the you are getting index as 0 which is the first index.
Hope you got my point ! Thumbs Up | :thumbsup:

problem with drawing a polygon

I want to draw a polygon using Graphic class on a webform, I use the following code but it doesn't show anything!!! D'Oh! | :doh:

protected void Page_Load(object sender, EventArgs e)
        {
            Bitmap objBitmap;
            Graphics objGraphics;

            objBitmap = new Bitmap(400, 440);
            objGraphics = Graphics.FromImage(objBitmap);
            objGraphics.Clear(Color.Blue); 
        }

even I delete all the HTML tag except

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="ImageResults.aspx.cs" Inherits="Yadgirandeh.WebForm5" %>;

I would be really grateful if anybody helps me.

You need to set the response type of the response, and then write the bitmap to the output stream of the response.

Something like (after your existing code)...

Response.ContentType = "image/jpeg";
Response.Clear();
Response.BufferOutput = true;
objBitmap.Save(Response.OutputStream, ImageFormat.Jpeg);
Response.Flush();

Assuming your other code is correct which I haven't really checked.

what have you done to isolate the problem? Is it the page rendering, the data access, or something else. How much ram? Is everything on a single machine? How much traffic? What is the network like? There are any number of things that could causing you problems, but with details we can't help

Hi,
I am mani. I have a problem in display the data in datagrid.
What i did is I am creating a form and in this form i created a 6 textboxes and one search button. whenever the user enter a text in textbox i retrieve the data from the database and displayed in the datagrid.
The problem is when the user again enter the text in text box the datagrid is filled with new data and last data will be lost. But i want that newly searching data should be displayed in datagrid including the last searching data.

This is my problem i sent last time to this portal. i got some answers. But using the DataTable i didnt get the answer. I write my code here. please tell me what is the wrong i did it in this.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;
public partial class AdvanceSearch : System.Web.UI.Page
{
SqlConnection con;
SqlCommand cmd;
SqlDataAdapter adptr;
DataTable dt;
DataView dv;

protected void Page_Load(object sender, EventArgs e)
{
if (Session["mani"] == null)
{
dt = new DataTable();
Session["mani"] = dt;
}
else
{
dt = (DataTable)Session["mani"];
}
dv = new DataView(dt);
SearchResultGrid.DataSource = dv;
SearchResultGrid.DataBind();

}
protected void ButtonSearch_Click(object sender, EventArgs e)
{
con = new SqlConnection("Data Source=MVB;Initial Catalog=Communication; Integrated Security=True");
string select_query = "SELECT *FROM CommunicationDetails WHERE CommunicationId=@comid OR IssueType=@issue OR RegionName=@regname OR ApplicationName=@appname OR Descript=@Desc OR CommunicationDate=@comdate";
cmd = new SqlCommand(select_query, con);
cmd.Parameters.Add("@comid", TextBoxCommunicationID.Text);
cmd.Parameters.Add("@issue", TextIssueType.Text);
cmd.Parameters.Add("@regname", TextBoxRegionName.Text);
cmd.Parameters.Add("@appname", TextBoxApplicationName.Text);
cmd.Parameters.Add("@Desc", TextBoxDescription.Text);
cmd.Parameters.Add("@comdate", TextBoxDate.Text);

try
{
con.Open();
adptr = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
adptr.Fill(ds);
dt = ds.Tables[0];
dv = new DataView(dt);
SearchResultGrid.DataSource = dv;
SearchResultGrid.DataBind();
con.Close()
}
catch(SqlException)
{
con.Close();
}
}
}

using this code i get the answer every time the user enter the data to search. but the last time the user searched data will be lost. i want that last time searching data including the present data.

regards,
Manikanta.

One possibility is that when you make a new query:
- save the last results in a datatable 1 (the currently binded datatable)
- execute a new query
- from the query save the results to datatable 2
- merge datatable 1 and 2 to datatable 3
- bind the datatable 3 to the grid

You can do this with two datatables also if you want. For information about Merge, see http://msdn.microsoft.com/en-us/library/fk68ew7b.aspx[^]
