Forms Data Controls :: Error - Gridview Fired Event "Sorting" Which Wasn't Handled Using Visual Studio 2008
Feb 21, 2010
I have a gridview in an update panel which is declared in an ASPX page, and bound to a SQLDataSource in code. The gridview's 'allowsorting' attribute is set to true, and because it is bound to a SQLDataSource, I expect the sorting to be automatically handled.
Yet I am getting the "Message: Sys.WebForms.PageRequestManagerServerErrorException: The GridView 'grdStatusItems' fired event Sorting which wasn't handled" error. I am using Visual Studio 2008, IE8, IIS7. What am I doing wrong? I have done anextensive search for this error, but it seems in most cases where this error occurs, the people are not using a SQLDatasource, so have to handle the sorting event themselves. Is this the case here? Here is the updatepanel and gridview declaration in the aspx file:

I have a page displays CRM data (with CrmService) in GridView. Everything run ok until I tried to sort out one field by default and I received the following exception: The GridView 'GridView1' fired event Sorting which wasn't handled. The reason I am using GridView to do the sorting because:
1) Cannot do it with SQL "ORDER BY" since date retrieval from CRM Web Service
2) Cannot use OrderExpression for QueryExpression from CRM because the column I want to sort is generated by my algorithm
GridView1.Sort("ColumnName" SortDirection.Descending);
in Page_Load, or Button1_Sort(object sender, GridViewSortEventArgs e), they all trigger the above execption!
I also added the method to the following method to handle exception, but didn't work:
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
GridView1.Sort("ColumnName" SortDirection.Descending);
}

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();

Why wasn't my GridView's RowDataBound event fired? I have a masterpage on whick i have a query button, and I have a content page on which i have a customized GridView(named cgvEmployees,derived from GridView). The logic is when user click the button, the button click event triggered that search the underlying database and populate the GridView.
Everything runs great except that RowDataBound event isn't triggered. Because I have to change some cells' representations in RowDataBound event handler. I have surfed so much pages to find the answer but failed. Below is what i have already done:
1. set the autoeventwireup to true;
2. i have a cgvEmployees.bind() sentence in the button click event handler;
3. i have OnRowDataBound="cgvEmployees_OnRowDataBound" in the content page GridView tag attribute
by the way, the database query is coded by Linq Dynamic Query (please google 'dynamic Linq').
void Master_QueryButton_Click(object sender, EventArgs e)
{
RetiredEmployeeDataContext db = new RetiredEmployeeDataContext();
NameValueCollection nvcQueryKeyValue = getNVCQueryKeyValue();
Expression<Func<RetiredEmployee, bool>> searchPredicate = getLambdaExpr(nvcQueryKeyValue);
IQueryable<RetiredEmployee> retireds = db.RetiredEmployees;
Expression expr = Expression.Call(typeof(Queryable), "Where",
new Type[] { typeof(RetiredEmployee) }, Expression.Constant(retireds), searchPredicate);
IQueryable<RetiredEmployee> query = db.RetiredEmployees.AsQueryable().Provider.CreateQuery<RetiredEmployee>(expr);
List<RetiredEmployee> employeeList = new List<RetiredEmployee>(query);
List<RetiredEmployeeEO> employees = new List<RetiredEmployeeEO>();
foreach (RetiredEmployee employee in employeeList)
{
RetiredEmployeeEO employeeEO = new RetiredEmployeeEO();
employeeEO.MapEntityToProperties(employee);
employees.Add(employeeEO);
}
cgvEmployees1.ListClassName = typeof(RetiredEmployeeEOList).AssemblyQualifiedName;
cgvEmployees1.LoadMethodName = "LoadFromQuery";
cgvEmployees1.LoadMethodParameters.Clear();
cgvEmployees1.LoadMethodParameters.Add(employees);
cgvEmployees1.DataBind();
}
protected void cgvEmployees1_RowDataBound(object sender, GridViewRowEventArgs e)

if (e.Row.RowType == DataControlRowType.DataRow)
{
//Add the edit link to the action column.

}
else

}

if(e.Row.Cells[0].Controls.Count==0)
e.Row.Cells[0].Controls.Add(editLink);
//Add checkbox to display the isactive field.
CheckBox chkActive = new CheckBox();
chkActive.Checked = ((RetiredEmployeeEO)e.Row.DataItem).liveOrDead;
chkActive.Enabled = false;
if(e.Row.Cells[24].Controls.Count==0)

I have in my laptop VS 2003, VS 2005 and VS 2008. I am making some SMS application in which I am using some DLL which need asp.net 3.5 so I am making application VS 2008. Now in my application I am using DAL and BLL method where in I am making .xsd file with TableAdapted from that I am making BLL files.
I added Formview in my aspx page configure it with Objectdatasource . IDE was not invoking the wizard for objectdatasource after lot finding. I got from some forum that after removing bin folder from application. It will start working. This was the first problem now I add gridview in my aspx page now and configure with Object data source. But when I go property builder of gridview I cannot see Edit Template, I can see only Empty template and Pager Template. Here my question this is new in VS 2008 as when i was working with VS 2005 I could see all Template. Next thing when change anything through property builder, I can see changes in the design view mode but I cannot see any changes in HTML source view. Again when I switch back to HTML source view to design mode all changes will go away. Why is it so !! For more info I will put my aspx, aspx.vb page code here.

I have a very simple asp.net page, just some buttons and one GridView on it. The logic is a user click the QUery button,then the button click event was trigured to populate the gridview with data queried from database via LINQ. for a user friendly interface, in RowDataBound event, I visit every row, change a boolean value into checkbox represention. But it seem that the RowDataBound run twice, because the checkboxs were inserted twice for every row in one cell. so why? the source code snippet as follow:
protected void btnSelect_Click(object sender, EventArgs e)
{
RetiredEmployeeDataContext db = new RetiredEmployeeDataContext();
GridView1.DataSource = db.ENTUserAccountSelectAll();//userAccounts;
GridView1.DataBind();
}
protected void GridView1_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox chkActive = new CheckBox();
chkActive.Checked = ((ENTUserAccount)e.Row.DataItem).IsActive;
chkActive.Enabled = false;
e.Row.Cells[5].Controls.Add(chkActive);
}
}

I have a Gridview which contains templated column that has 5 checkboxes in it. When you click on one checkbox, I want to uncheck the other 4.
I am using the Item Template for this. I don't want the user to have to Select a row, before clicking on the checkboxes. Here is my non-working code to uncheck the other checkboxes. I realize it's not "SelectedRow" that I want since there's no selected row, so how do I find the row containing the checkbox that fired off CheckChanged?

since APS.Net 4.0 I have a curious problem with an event.
There is a FormView and inside of the EditItem there is a GridView. In the Footer of the GridView I put Controls for inserting records.
But when I fire a markup defined RowCommand of that GridView then the same event is getting fired for the Parent FormView. First I had 'Insert' as the CommandName and so I was getting the Error that my FormView had to be in insert mode to insert a record. Then I changed the RowCommand of the GridView to 'xxx' and I got also the RowCommand 'xxx' at the RowCommand eventhandler of the Parent FormView.
The project was migrated from .Net 3.5 a few days ago, but nothing was manually changed in the code/markup. And the problem was not there with the "old" framework.
[Code]....
Of course, I could simply change the CommanName of the LinkButton e.g. to 'InsertChild' but I would like to know:
Is this a known change or a bug of ASP.Net 4.0?

So I have a GridView control with autogenerated column set to true, it also has autogenerated Edit and Delete buttons, sorting and paging, and also I am binding this same gridview to multiple data sources at runtime. All is working well.
Now I am adding a dynamically generated footer row at runtime. This footer row will allow users to add new record regardless which data source it binds to. So it is working as well except there's a small bug I couldn't figure out why. It's when I navigate to the last page of the gridview, if the rows on the last page is less than the page size, for example, I have page size 10 and the rows in last page is 9, then when I click the 'Add' linkbutton, the Add event does not fire, instead, it fill the last page with additional blank rows, that means if the last page has 5 rows, it will fill 5 blank rows below, if it has 9 rows, it will fill 1 blank row below. Then if you click the add again, it will work. If the last page already has 10 rows then, it works just fine.
Below is the code I used to dynamically add footer row:

I have a page on which everything is loaded dynamically.
There is a Gridview (AutoGenerateColumns=true) and in the RowDataBound I check every column for a boolean datatype. If found I add a checkbox (autopostback=true) to the cell and register the CheckedChanged event.
The problem is, that I only get the CheckedChanged event, if I reload the grid in Page_Load:
protected void Page_Load(object sender, EventArgs e) {
LoadGrid();
}
But this is very expensive and causes that the db request will be executed twice. If I changed the code to what I want:
protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack)
loadGrid();
}
I get no CheckedChanged event.
Is there a possibility to get:
- Adding a Checkbox in RowDataBound
- Only "LoadGrid()" if it is no PostBack
- Getting the CheckedChanged event of the relevant row

Background: I use SQL server 2005 developer edition and visual studio 2008. Visual studio 2008 is running on a local machine with Vista business edition. SQL server is running on a remote server using Windows server 2003. Both computers are within the same domain.
Problem: First, I used the server explorer to connect to the SQL server. Everything works as desired. Then I write code to do the same thing. I keep getting the following error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid)
However, I used the exactly identical connection string as the one used in the server explorer. So connection string should not be the problem. In addition, I tried the test code in MSDN, which tells whether my domainusername can flow the network. It turns out the user name is fine. I also went to the SQL server management studio and found the login for my computer is NVCWeihao while my computer login name is NVCweihao. I am wondering if this uppercase letter really affects the connection.

Is there any tool for Visual Studio 2008 which can reformat ASPX code to make it more presentable (eg insert line breaks, format the lines so they wrap when necessary, etc)?
