Webpage hangs after the On_Unload event - c#

Need your help guys.
I have a web application which hangs after clicking a checkbox which is set to autopostback. This checkbox is supposed to do some process.
It didn't fire the OnPreLoad and the OnLoad events.
Below are the codes

There is an error somewhere in your OnInit
Try placing try catch blocks around each step and step into (not over) each function in there to see if you have any problems.
My guess is you have a try...catch with an empty catch statement - otherwise you'd have an exception to deal with.
We really need to see the code behind, its probably obvious to some of us here when we see the code.

I found the answer to my problem.
There's one event that is not used, and it is this.
rgEndorsements.ItemEvent += new GridItemEventHandler(rgEndorsements_ItemEvent);
It seems that we must check if all the events that are "instantiated" are being used. Thanks for your suggestions! Highly appreciate 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.

Master/Details ASP.NET C# DataGrid?

I want to display data Master/Details stype with DataGrid not GridView or anything else. At the present I must put a dropdownlist to do this manually. So how can do it automatically whenever we click one master item in the Master DataGrid then it link to Details DataGird , like this:

Datagridview c# with SQL for Professional Developer

First of all I will give short description about my App:
C# application uses sql server to share "Tasks" between team
All user see the tasks
The event happens when user check the checkbox
I use a timer to refresh the grid every 4 seconds
Timer code:
private static int second = 0;
private void timer1_Tick(object sender, EventArgs e)
{
try
{
second++;
List<Tasks> list=taskController.taskController.GetList();
_FillGridFromList(list);
_RefreshGrid();
}
catch (Exception ex)
{
MessageBox.Show(this, ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
/*reFill the grid*/
private void _RefreshGrid()
{
try
{
List<Tasks> list = taskController.taskController.GetList();
_FillGridFromList(list);
}
catch (Exception ex)
{
MessageBox.Show(this, "Unable to Retrive Data from Server", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
/*This function will fill userGridView from Arraylist that get from SQL */
private void _FillGridFromList(List<Tasks> list)
{
dataGridView1.ClearSelection();
try
{
DataTable table1 = new DataTable("sheet");
System.Data.DataSet tmpSet = new System.Data.DataSet();
DataRow row = table1.NewRow();
table1.Columns.Add("ID");
table1.Columns.Add("Title");
table1.Columns.Add("Description");
table1.Columns.Add("Preiority");
table1.Columns.Add("Status");
table1.Columns.Add("Done By");
table1.Columns.Add("Start Date");
int j = 0;
for (int i = 0; i < list.Count; i++)
{
Tasks tmp = (Tasks)list[i];
row[j++] = tmp.ID;
row[j++] = tmp.Name;
row[j++] = tmp.Description;
row[j++] = tmp.Preiority;
row[j++] = tmp.Status;
row[j++] = tmp.Done_By;
row[j++] = tmp.Start_Date;
j = 0;
table1.Rows.Add(row);
row = table1.NewRow();
}
tmpSet.Tables.Add(table1);
dataGridView1.DataSource = tmpSet.Tables[0];
// dataGridView1.ReadOnly = true;
dataGridView1.Columns[1].ReadOnly = true;
dataGridView1.Columns[2].ReadOnly = true;
dataGridView1.Columns[3].ReadOnly = true;
dataGridView1.Columns[4].ReadOnly = true;

{
dataGridView1.Rows[i].Cells[0].ReadOnly = true;
}
else
{
dataGridView1.Rows[i].Cells[0].ReadOnly = false;
}
}
else
{
dataGridView1.Rows[i].Cells[0].Value = false;
}
}
}
catch (Exception e)
{
MessageBox.Show(this, e.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
private void dataGridView1_CellValueChanged_1(object sender, DataGridViewCellEventArgs e)
{
try
{
if(second > 5)
{
foreach (DataGridViewRow dr in dataGridView1.Rows)
{
DataGridViewCheckBoxCell drx = (DataGridViewCheckBoxCell)dr.Cells[0];
if(sender == drx)
if (drx.Selected != null) //Cells[0] Because in cell 0th cell we have added checkbox
{
if (drx.Selected==true && dr.Cells[6].Value.ToString() == utility.Util.User.Display_Name)
{
Tasks tsk = taskController.taskController.Read(dr.Cells[1].Value + "");
{
tsk.Done_By = "";
tsk.Status = "";
taskController.taskController.Update(tsk);
}
}
else
{
if (drx.Selected !=true)
{
Tasks tsk = taskController.taskController.Read(dr.Cells[1].Value + "");
tsk.Done_By = utility.Util.User.Display_Name;
tsk.Status = "Closed";
taskController.taskController.Update(tsk);
}
}
}
}
}
}
catch (Exception ex)
{
MessageBox.Show(this, ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
The main problem is that when I fill the form again the listener is called because I rebuild the gridview.
http://i.stack.imgur.com/l0Rdv.png
I solve the problem by using the below code :
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
//MessageBox.Show(e.RowIndex+" "+e.ColumnIndex);
// Int32 selectedRowCount = dataGridView1.Rows.GetRowCount(DataGridViewElementStates.Selected);
// Int32 selectedColumnCount = dataGridView1.Columns.GetColumnCount(DataGridViewElementStates.Selected);
if ( e.ColumnIndex == 0 && e.RowIndex >= 0 )
{
string x=dataGridView1.Rows[e.RowIndex-1].Cells[6].Value.ToString();
if ((bool)dataGridView1.Rows[e.RowIndex-1].Cells[0].Value == false && x!=null )
{
if(x==Util.User.Display_Name)
{
Tasks tsk = taskController.taskController.Read(dataGridView1.Rows[e.RowIndex-1].Cells[1].Value + "");
tsk.Done_By = "";
tsk.Status = "";
taskController.taskController.Update(tsk);
dataGridView1.Rows[0].Cells[1].Value = true;
}
}
else
{
if ((bool)dataGridView1.Rows[e.RowIndex-1].Cells[0].Value == true)
{
Tasks tsk = taskController.taskController.Read(dataGridView1.Rows[e.RowIndex-1].Cells[1].Value + "");
tsk.Done_By = utility.Util.User.Display_Name;
tsk.Status = "Closed";
taskController.taskController.Update(tsk);
}
}
}
}
I only change the type of listener from private void dataGridView1_CellValueChanged_1
to
private void dataGridView1_CellContentClick

Unable to move files into devexpress file treelist

How to fix this?

I want to update only those columns in my database whose textboxes are enabled and keep previous data for those which are disabled?

(http://s14.directupload.net/images/140127/fooispgt.jpg) Link for image
Please view image for more clarification of the problem bcz i know i'm not able to make it more clear to you.
I want to update data for only those columns which are checked by user via checkboxes and those which are left unchecked don't get updated by NULL value....
what i'm thinking is use 511 if....else conditions each for different update query but it's not possible to implement this.
till now the code for update is this:
else if(update_rdbtn.Checked)
{
FileStream fstream = new FileStream(this.imglocation_lbl.Text, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fstream);
imgbtarray = br.ReadBytes((int)fstream.Length);
SqlConnection con = new SqlConnection("Data Source=JackSparrow-PC\\sqlexpress;Initial Catalog=HCE_DB;Integrated Security=True;Pooling=False");
SqlCommand cmd = new SqlCommand("Update StudentInfo SET Rollno='" + this.rollno_txtbox.Text + "',Student_Name='" + this.studname_txtbox.Text + "',F_name='" + this.fname_txtbox.Text + "',D_O_B='" + this.dob_txtbox.Text + "',Address='" + this.address_txtbox.Text + "',Phone='" + this.phone_txtbox.Text + "',Valid_upto='" + this.validupto_txtbox.Text + "',Image=#IMG,Branch='" + this.branch_txtbox.Text + "' WHERE Rollno='" + this.rollno_txtbox.Text + "';", con);
SqlDataReader myReader;
try
{
con.Open();
cmd.Parameters.Add(new SqlParameter("#IMG", imgbtarray));
myReader = cmd.ExecuteReader();
MessageBox.Show("Data has been updated");
myReader.Close();
con.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
