We Keep Coding

The Value of textbox is still appear After page reload in Asp.Net

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Request.Cookies["UserName"] != null && Request.Cookies["Password"] != null)
{
txtUserName.Text = Request.Cookies["UserName"].Value;
txtPass.Attributes.Add("value", Convert.ToString(Request.Cookies["Password"].Value));
CheckBox1.Checked = true;
}
}
}
protected void btnLogIn_Click(object sender, EventArgs e)
{
if (dt.Rows.Count != 0)
{ }
else
{
lblMsg.Visible = true;
lblMsg.Text = "Login In Failed";
}
ClearField();
}
}
protected void ClearField()
{
txtUserName.Text = string.Empty;
txtPass.Text = string.Empty;
}
When my else condition execute. it not empty my txtPass Textbox instead if i write wrong password it display correct password in textbox.
i think something wrong with Cookie but idk how to solve it.

You can keep a boolean field in your code and set its value to true whenever the select all is clicked. When loading new pages, you can check that field to automatically display all checked. The same can be done when exporting the grid also.

you can modify and use the following Method
private void selectAllChecksInDAtaGrid()
{
foreach (DataGridViewRow item in myDataGrid.Rows)
{
if (Convert.ToBoolean(item.Cells["Column_Name"].Value) == false)
{
item.Cells["Column_Name"].Value = true;
}
}
}
the 'Column_name' is the name of the checkbox column. if you haven'nt named it yet you can also use the index number .
in your case its 0
private void selectAllChecksInDAtaGrid()
{
foreach (DataGridViewRow item in myDataGrid.Rows)
{
if (Convert.ToBoolean(item.Cells[0].Value) == false)
{
item.Cells[0].Value = true;
}
}
}

You should update (ArrayList)Session["BP_PrdId"] to include all the "Id"s of datasource of gridview. then bind data again.

How to check if cookies are enabled or disabled in asp.net?

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Request.Browser.Cookies)
{
if (Request.QueryString["check"] == null)
{
HttpCookie cookie = new HttpCookie("testcookie");
Response.Cookies.Add(cookie);
Response.Redirect("Default.aspx?check=1");
}
else
{
HttpCookie cookie = Request.Cookies["testcookie"];
if(cookie==null)
{
Label1.Text = "enable cookies";
}
}
}
else
{
Label1.Text = "cookies not supported:";
}
}
}
protected void Button1_Click(object sender, EventArgs e)
{
HttpCookie cookie = new HttpCookie("userinfo");
cookie["name"] = TextBox1.Text;
cookie["email"] = TextBox2.Text;
//cookie.Expires = DateTime.Now.AddDays(30);
Response.Cookies.Add(cookie);
Response.Redirect("Default2.aspx");
}
It's not working correctly.

See the following link.
http://forums.asp.net/t/1044823.aspx?How+to+check+cookies+enabled+in+a+web+browser+
The only way to check is set a cookie then redirect it and again check if you are able to access it or not. So try below method mentioned in above link.
protected void Page_Load(object sender, EventArgs e)
{
if (this.IsCookieDisabled())
errorMsgLabel.Text = Resources.Resource.BrowserDontSupportCookies;
}
private bool IsCookieDisabled()
{
string currentUrl = Request.RawUrl;
if (Request.QueryString["cookieCheck"] == null)
{
try
{
HttpCookie c = new HttpCookie("SupportCookies", "true");
Response.Cookies.Add(c);
if (currentUrl.IndexOf("?") > 0)
currentUrl = currentUrl + "&cookieCheck=true";
else
currentUrl = currentUrl + "?cookieCheck=true";
Response.Redirect(currentUrl);
}
catch(Exception ex)
{
return false;
}
}
if (!Request.Browser.Cookies || Request.Cookies["SupportCookies"] == null)
return true;
return false;
}

Bind GridView on Button Click Event with Pagination

I'm new to asp.net and needs some help. I have a gridview with paging for every 20 records per page, I have a search button outside the gridview. What I need to do is when I click the search button, the results must be bind to gridview(which is happening now), however when the records are more than the pagesize and I need to go to the next page of the grid, the binding is lost and the binded records are the ones form the page on load event. below is my code sample.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindData();
}
}
public void BindData()
{
{
List<EventFile> eventFile = new List<EventFile>();
eventFile = CoMailAssociationDAL.GetUploadFileUnAssigned(0, "", "", "U");
if (gvwAssociation.DataSource == null)
{
gvwAssociation.DataSource = eventFile;
gvwAssociation.DataBind();
}
}
}
protected void btnSearch_Click(object sender, EventArgs e)
{
int uFlag = 0;
string uploadFlag = this.ddlUploadDate.SelectedValue;
string fileName = this.txtSearchText.Text;
string uploadDt = this.txtDate.Text;
string status = this.ddlStatus.SelectedValue.ToString();
bt = true;
if (status == "Un-Assigned")
{
status = "U";
}
else if (status == "Assigned")
{
status = "A";
}
else
{
status = "B";
}
if ((uploadFlag == "On") && (uploadDt == ""))
{
uFlag = 0;
}
else if (uploadFlag == "On")
{
uFlag = 1;
}
else if (uploadFlag == "OnorBefore")
{
uFlag = 2;
}
else
{
uFlag = 3;
}
fileSearch = CoMailAssociationDAL.SearchFile(uFlag, fileName, uploadDt, status);
gvwAssociation.DataSource = fileSearch;
gvwAssociation.DataBind();
}
protected void gvwAssociation_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
//SaveSelectedValues();
gvwAssociation.PageIndex = e.NewPageIndex;
//BindData();
//PopulateSelectedValues();
}

First of all you should have the following event handler for paging
protected void gvwAssociation_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvwAssociation.PageIndex = e.NewPageIndex;
bindGridWithFilter();
}
Then, move your search/ filter logic within the search button to a private method (say "bindGridWithFilter")
TIP: Try to combine both BindData and bindGridWithFilter so when there's no filter you display all records
UPDATE
Here's some refactored code for you to get an idea what I meant above.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bindGridWithFilter();
}
}
protected void gvwAssociation_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvwAssociation.PageIndex = e.NewPageIndex;
bindGridWithFilter();
}
protected void btnSearch_Click(object sender, EventArgs e)
{
bindGridWithFilter();
}
private void bindGridWithFilter()
{
List<EventFile> eventFile = new List<EventFile>();
eventFile = CoMailAssociationDAL.GetUploadFileUnAssigned(0, "", "", "U");
if (gvwAssociation.DataSource == null)
{
// If you don't have a filter you show all records
gvwAssociation.DataSource = eventFile;
gvwAssociation.DataBind();
}
else
{
// This is same as the logic in your search button
// display only the filtered records
int uFlag = 0;
string uploadFlag = this.ddlUploadDate.SelectedValue;
string fileName = this.txtSearchText.Text;
string uploadDt = this.txtDate.Text;
string status = this.ddlStatus.SelectedValue.ToString();
bt = true;
if (status == "Un-Assigned")
{
status = "U";
}
else if (status == "Assigned")
{
status = "A";
}
else
{
status = "B";
}
if ((uploadFlag == "On") && (uploadDt == ""))
{
uFlag = 0;
}
else if (uploadFlag == "On")
{
uFlag = 1;
}
else if (uploadFlag == "OnorBefore")
{
uFlag = 2;
}
else
{
uFlag = 3;
}
List<EventFile> fileSearch = CoMailAssociationDAL.SearchFile(uFlag, fileName, uploadDt, status);
gvwAssociation.DataSource = fileSearch;
gvwAssociation.DataBind();
}
}
This should work.

Removing particular items from menu and replacing the new menu through content page in asp.net?

I have a menu and label in my master page which i want to update depending on the type of user logged in.
Firstly am removing few MenuItems from the menu that is working fine but its not showing up in the master page. Instead the old menu is only seen with all the menu items for limited user also. When i debug the label text shows what i have set but when page loads its not updating too.
Am using the following code.
Label lbWelcomeMessage = new Label();
protected void Page_Load(object sender, EventArgs e)
{
Master.FindControl("CAMenu").Visible = false;
}
protected void btnLogin_Click(object sender, EventArgs e)
{
string userName = txtUsername.Text;
string password = txtPassword.Text;
Common common = new Common();
DataTable tab = new DataTable();
tab= common.GetUserDetails(userName);
string firstName = string.Empty;
string userPassword = string.Empty;
string RoleID=string.Empty;
if (tab.Rows.Count == 1)
{
firstName = tab.Rows[0][2].ToString();
userPassword = tab.Rows[0][4].ToString();
RoleID = tab.Rows[0][5].ToString();
}
if (userPassword == password)
{
if (RoleID != "1")
{
Menu CAMenu = new Menu();
CAMenu = (Menu)Master.FindControl("CAMenu");
int count = CAMenu.Items.Count;
for (int i = 3; i > 0; i--)
{
string text = CAMenu.Items[i - 1].Text;
CAMenu.Items.RemoveAt(i - 1);
}
lbWelcomeMessage = (Label)Master.FindControl("lbLoginMessage");
lbWelcomeMessage.Text = "Welcome"+" "+ firstName;
((SiteMaster)Page.Master).MyText = lbWelcomeMessage.Text;
Response.Redirect("AdHocSMS.aspx");
}
else
{
lbWelcomeMessage = (Label)Master.FindControl("lbLoginMessage");
lbWelcomeMessage.Text = lbWelcomeMessage.Text+" "+firstName ;
Response.Redirect("NewTemplate.aspx");
}
}
}

I assume you have written this code in your login.aspx. When login button is clicked then it takes you to another page and all the life cycle of page is run again. and master page contents are reset.
The solution to this problem could be. Move this logic to your master page code like
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
if (Session.Count == 0 || Session["Username"] == null)
Response.Redirect("~/Login.aspx", true);
CheckRole();
}
public void CheckRole()
{
if (System.Web.HttpContext.Current.Session.Count > 0)
{
tab= common.GetUserDetails(Session["Username"]);
if (tab.Rows.Count == 1)
{
firstName = tab.Rows[0][2].ToString();
userPassword = tab.Rows[0][4].ToString();
RoleID = tab.Rows[0][5].ToString();
}
if (RoleID != "1")
{
Menu CAMenu = new Menu();
int count = CAMenu.Items.Count;
for (int i = 3; i > 0; i--)
{
string text = CAMenu.Items[i - 1].Text;
CAMenu.Items.RemoveAt(i - 1);
}
//your label logic
lbWelcomeMessage.Text = "Welcome"+" "+ firstName;
((SiteMaster)Page.Master).MyText = lbWelcomeMessage.Text;
Response.Redirect("AdHocSMS.aspx");
}
else
{
//Logic
Response.Redirect("NewTemplate.aspx");
}
}
else
{
Session.Abandon();
Response.Redirect("~/Login.aspx", true);
}
}
You have to put a UserId or Username in Session this is the one disadvantage but for every page you dont have to worry about anything.
for life cycle read this article http://msdn.microsoft.com/en-us/library/ms178472.aspx
let me know if it solves or not.

What i did is something like this
In Site.Mater:-
public void CheckRole()
{
try
{
if (System.Web.HttpContext.Current.Session.Count > 0)
{
string firstName = string.Empty;
// string userPassword = string.Empty;
string RoleID = string.Empty;
Common common = new Common();
DataTable tab = new DataTable();
string userName = (string)Session["UserName"];
User user = new User(userName);
tab = user.GetUserDetails(userName);
if (tab.Rows.Count == 1)
{
firstName = tab.Rows[0][1].ToString();
RoleID = tab.Rows[0][3].ToString();
}
if (RoleID != "1")
{
int count = CAMenu.Items.Count;
if (count == 5)
{
for (int menuCount = 3; menuCount > 0; menuCount--)
{
string text = CAMenu.Items[menuCount - 1].Text;
CAMenu.Items.RemoveAt(menuCount - 1);
}
}
lbLoginMessage.Text = "Welcome," + " " + firstName;
loginStatus.Visible = true;
}
else
{
lbLoginMessage.Text = "Welcome," + " " + firstName;
loginStatus.Visible = true;
}
}
