Update MySQL using HyperLink ASP.NET - c#

I store all data in MySQL and display it's some colums in gridview. Gridview's delete button works fine. I would like to edit datas so created HyperLink. it navigates another url and gets values from MySQL DB and sets textboxes, textareas. Everything is fine until this time but I try to edit values in new page it sets old values in DB. How i can solve this problem?
This my Main Page which has gridview and delete button, hyperlink KayitGoruntule.aspx;

The textboxes on your form are being populated with their database defaults in the Page_Load event. This is fine the first time through; however, when you click your 'degistir' button, a "postback" occurs, and Page_Load fires again and repopulates those defaults, losing whatever changes were submitted. Keep in mind that Page_Load fires before any control click events.
To fix this, you need to check for IsPostback in Page_Load to prevent your loader from firing on the update. If IsPostback is true, inhibit the load of the defaults from your database. This, in turn, should allow the update to occur with the updated data provided on your form. Something along these lines:
// code snipped...
if (Session["kullanici"] != null)
{
Response.Write("Hoşgeldiniz..." + Session["kullanici"]);
Response.Redirect("KayitAyrinti.aspx");
}
else
{
// Response.Write("Giriş Yapınız.");
}
if (!IsPostback) // <-- Add this check
{
string connectionString = "xxx;Database=xxx;Uid=xxxx;Pwd=xxx;";
using (MySqlConnection cn = new MySqlConnection(connectionString))
{
string[] keys = Request.QueryString.GetValues("id");
/// rest of code snipped
Also, be sure to modify your UPDATE statement to include a WHERE clause that limits the UPDATE to only that record with the desired ID. As it is, ALL your records will be updated!

radio button in gridview template field

I am making a exam web application in ASP.NET. I am using grid-view for showing question and the possible answers. I set size of grid view is 1 so it display only one question on a page-index. I am using radio button for multiple choice option.
When I select a radio button and going to next question or next page index of grid-view and come again previous question then I see that the radio button which I selected previously is not selected. What should I do for this?

I'm getting this error while binding data to data list
too many characters in character literal asp.net

"too many characters in character literal" is caused by having a char-literal with too many characters in it.
You have probably mixed up the '-character and the "-character.
The error probably lies in your "android.aspx.cs"-file rather than the .aspx-file that you have provided.
Could you provide the code for that as well?
Well, your problems are right here:
<%# Bind('ModelID') %>
Replace your single-quotes with double-quotes and you will be golden!
<%# Bind("ModelID") %>
Same goes for all your Evals/Binds
Also see these questions:
Why I'm getting CS1012: "Too many characters in character literal" and CS0019?
Too many characters in character literal?

I think the origin of the error is:
Eval('brand')
It tries to convert brand to a character and fails with that error.

Try this
GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);
HiddenField empID = (HiddenField)row.FindControl("EmployeeID");
Session["Employee"] = empID.Value;

Try This:
Use Response.Redirect("UpdateEmployee.aspx",false);
instead of Response.Redirect("UpdateEmployee.aspx");
This is because of the way Redirect and session variables work.
When you create a new session an volatile cookie is set on the client that contains the session token. On all subsequent requests, and as long as the server session and the client cookie have not expired, ASP.NET can look at this cookie and find the right session.
what Redirect does is to send a special header to the client so that it asks the server for a different page than the one it was waiting for.
Hope this helps!!

How can I understand which columns value when I press the button?

I try to write data grid in aspx. In my database there is a column which name is 'PROJECT_NAME'. I want these columns in my data grid, then I add second column (editbox) to add values every each of project. This is all in grid view, and I add button in form. When I press the button how can I understand which columns value belong which project?
I mean, for example
Row value : A project 2 Column value : 50
Row value : B project 2 Column value : 60
Row value : C project 2 Column value : 70
I want to know when I press button 1. project value 50 how can ı understand this?
This is my aspx code :

Thanks.

Inside of Button1_Click you need need to loop through all the rows in the GridView and do a FindControl on each row to get the label and textbox. From that you can determine what the PRJ_PROJECT_NAME and values in the textbox are.
Here is an example:
Default.aspx
<asp:GridView ID="gvData" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="lblLabel" runat="server" Text='<%# Bind("Number") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="txtData" runat="server" Text='<%# Bind("Value") %>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:Button ID="btnSubmit" runat="server" OnClick="btnSubmit_Click" Text="Submit" />
Default.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
// Create some fake data and bind it to the gridview
var data = new List<TheData>();
foreach(var num in Enumerable.Range(1, 4))
{
var newData = new TheData();
newData.Number = num.ToString();
newData.Value = num;
data.Add(newData);
}
gvData.DataSource = data;
gvData.DataBind();
}
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
for (var index = 0; index < gvData.Rows.Count; ++index)
{
var row = gvData.Rows[index];
var lblLabel = row.FindControl("lblLabel") as Label;
var txtData = row.FindControl("txtData") as TextBox;
//Here is where the values are grabbed, at this point you can do what you need to.
var number = lblLabel.Text;
var value = txtData.Text;
}
}

one solution I have used before takes advantage of the CommandArgument attribute of the button. You can set the CommandArgument='<% Eval("ColumnValueYouWant") %>' and each button will get the value for the column in it's row. Then, in the click event you can parse the object sender back into a Button and access the CommandArgument value.
