I've got a gridview that returns student order history which works just fine. It pulls the StudentId from a hidden field on page load. I have a link button that ADDS AN ORDER when clicked. It calls a stored procedure, inserts the record, then rebinds the gridview and displays the new record at the top of the list.
Problem is when I go to EDIT it, i get this error... "The GridView 'GridViewOrderHistory' fired event RowEditing which wasn't handled." But the interesting thing is the error doesn't occur if I close the browser and reload the page and then click on that new record that was created. Obviously I'm missing something in my code when the new order is created. Here are the 2 subs involved in the process.

I am populating the gridview on the basis of listbox selection . However, I am setting the datasource in the click event after listbox entry. When i am trying to update any record in the gridview this error gets thrown because the datasourceid from the aspx page has been removed. Code for reference -
protected void btn_save_Click(object sender, EventArgs e)
{
ArrayList list = new ArrayList();
foreach (object o in ListBox2.Items)
{
list.Add(o);
}
string str2 = null, str, host;
string str1 = "SELECT SYSTEMNAME, DATETIME, PDOWNTIME, UDOWNTIME, SYSDOWNMINS, REASON FROM PLANNED_DOWNTIME where ";
host = Convert.ToString(list[0]);
str2 = " ( SYSTEMNAME like '" + host + "'";
for (int i = 1; i < list.Count; i++)
{
host = Convert.ToString(list[i]);
str2 = str2 + " or SYSTEMNAME LIKE'" + host + "'";
}
str = str1 + str2 + " )";
string connectstring = "Data Source=SRCPA035\ovops;Initial Catalog=reporter;Persist Security Info=True;User ID=sa;Password=ril123";
DataTable dt = new DataTable();
SqlConnection connection = new SqlConnection(connectstring);
try
{
connection.Open();
SqlCommand sqlCmd = new SqlCommand(str, connection);
SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd);
sqlDa.Fill(dt);
if (dt.Rows.Count > 0)
{
GridView1.DataSource = dt;
GridView1.DataBind();
}
GridView1.DataSource = SqlDataSource1;
}
catch (System.Data.SqlClient.SqlException ex)
{
string msg = "Fetch Error:";
msg += ex.Message;
throw new Exception(msg);
}
finally
{
connection.Close();
}
}

Basically, I have a gridview and it has RowEditing function, which to be fair has two lines of code
GridView1.EditIndex = e.NewEditIndex;
GridView1.DataBind();
When I press the edit button from one of the row in gridview, it hides the whole gridview!
To bring it back, I have to call the function which does the binding and suprisingly, it loads back in edit mode!

why the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?

all of a sudden my GridView has stopped firing the row update event. Friday I was working on it and was working flawlessly. Now I haven't made any changes to the code and all of a suddent has stopped working (yes rediculously bizarre and have been banging my head all day thinking what the something is wrong with it, excuse my french).
Everyone of those events fire except the update. I click the update button and nothing happens.

I ask for a date, on OnTextChanged event i bind data with a SqlDataSource to a dropdownlist and also bind data to a repeater passing the dropdownlist SelectedIndex (i use SqlDataSource too and ControlParameter to link the dropdownlist and the repeater) On my repeater during the ItemDataBound event i create dynamic dropdownlist controls, my code is :
[Code]....
[Code]....
On the Page_load event of my page i bind the data & recreate the control :
[Code]....
Everything works fine, datas are bound and SelectedIndexes are restore on every postback.
The probem occurs when user change different dropdownlists, if he choose to change the 1st dropdownlist the event is fire (normal), after if he modifies another dropdownlist the event is fire twice, if he modifies a 3rd time the event is fire 3 time etc...

I have one UpdatePanel which contains search criteria controls for a GridView.
The GridView is in another UpdatePanel.
I have a reset button in the search criteria UpdatPanel which resets all the search controls to their default values. However when I click this button for some reason my GridView RowDataBound method fires.
This is slowing the page down when the reset button is clicked. Does anyone know why this is happening and how to stop it. I haven't posted the code and explained it in plain english for ease of reading.

i read article "using javascript with asp.net radiobuttonlist control" and i found it useful.
[var RB1 = document.getElementById("<%=RadioButtonList1.ClientID%>");
var radio = RB1.getElementsByTagName("input");
if am setting radio[1].checked = 1; the item is checked. ]
step1: radio[0]=checked
radio[1]=not checked
radio[2]=not checked
step 2: by using javascript , am changing the selection
now
radio[0]=not checked
radio[1]=checked
radio[2]=not checked
step 3: if am changing radio[0]=checked by clicking, it wont fire the selected index change that i wrote on code behind
but if am changing radio[2]=checked by clicking, it will fire the selected index change that i wrote on code behind
My requirement: i want to fire the selected index change in both cases. for that i need to change the selected index in step 2.

I have visual 2010 with net 3.5 web app. I was implementing EntityFramework in my project and added a gridview to a entity source control. It worked ok, with select, update, and delete buttons enabled on the grid. But then, i needed to add a template field bound to a Foreign table, so my users select value from a list instead of writing the code. After that, my app fires error when i delete. I tried everything, inclue dakeyNames, write code on my RowDeleting, RowDeleted, RowCommand, but error persists.
Now, i can delete the row, but it then i get the error Object reference not set to an instance of an object If i implemente delete code on RowCommand i get the error: Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries.

I've been hunting for a solution to grab the radiobuttonlist when they answer that particular question. It varies for the number of questions, but only one displays at a time, but there could be a radiobuttolist or checkboxlist based on the question type. I was figuring I could do this easy in the row command of the gridview, but that hasn't worked out so well since I can't get the datarow for some reason.

I have a gridview that has a radiobuttonlist ( YES/NO ) selections. but since you cant uncheck once selected, they are asking to add a clear option so that if they make a mistake they can clear it..
How can i do that within a gridview so that they can clear any mistakes prior to submission?
I have a loop checking all my radiobuttons to perform an update, so if i would like to be able to clear the selection as soon as the click on "Clear" so when they submit, that row shows as if it was never selected.
