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 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!
I have a data field "Gender" (sql data type - bit).
I have created bound the data with if condition to check true-> male otherwise -> female. But it still does not display.
Here is the aspx and code behind code:The gridview shows true/false instead of male/female:

The gridview Gender column shows true/false instead of male/female.
Thanks!
You need a TemplateField for this. Assuming Male equates to True, this should work:
<asp:TemplateField HeaderText="Gender" SortExpression="Gender">
<ItemTemplate><%# (Boolean.Parse(Eval("Gender").ToString())) ? "Male" : "Female" %></ItemTemplate>

I have 2 ASPxGridView controls
- gvPatient and
- gvOrder
gvOrder is placed inside detail row template of gvPatient.
the issue i am faciing is i have to get the values of rows of gvOrder(child) on focus row changed or selection changed. I have code for these events but these events do not fire on selection changed of rows and focus changed of child grid . Strange this- here these child grid events fire on gvPatient(parent) row selection and focus changed.

You need to set properties SettingsBehavior.ProcessSelectionChangedOnServer and
SettingsBehavior.ProcessFocusedRowChangedOnServer to true.
From docs: "If the ProcessSelectionChangedOnServer property is set to false, the ASPxClientGridView.SelectionChanged event is handled on the client side without a postback to the server".
I have a GridView which allows users to enter data using a EmptyDataTemplate. There is a text box having a calendarextender. I want to get the date entered (format MM/dd/yyyy) and pass it to the database.

Basically, I want to fetch the values from the NodataToDt & NodatafrmDt textboxes in codebehind and pass the values to my stored procedure.
Thanks
In your code behind:
// Find the 2 text boxes within your GridView control
TextBox toDateTextBox = (TextBox)GV_Rotl_Asgt.FindControl("NodataToDt");
TextBox fromDateTextBox = (TextBox)GV_Rotl_Asgt.FindControl("NodatafrmDt");
// Grab the values out of those text boxes
string toDate = toDateTextBox.Text;
string fromDate = fromDateTextBox.Text;
From there, you can do whatever you need with those two string values.
