Drag and drop a GridView and name it as GridView1
Try the below code for merging the header
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable("Employee");
//Name Age Gender Mobile Phone Email
dt.Columns.Add("Name");
dt.Columns.Add("Age");
dt.Columns.Add("Gender");
dt.Columns.Add("Mobile");
dt.Columns.Add("Phone");
dt.Columns.Add("Email");
dt.Rows.Add("Anoop", "25", "Male", "996633352", "02255566", "anoopukrish@gmail.com");
GridView1.DataSource = dt;
GridView1.DataBind();
}
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
GridView gridView = (GridView)sender;
GridViewRow gridViewRow = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);
TableCell tableCell = new TableCell();
//add Personal Info
tableCell.Text = "Personal Info";
tableCell.Attributes.Add("style", "text-align: center");
tableCell.ColumnSpan = 3;
gridViewRow.Cells.Add(tableCell);
//Add Contact Info
tableCell = new TableCell();
tableCell.Attributes.Add("style", "text-align: center");
tableCell.Text = "Contact Info";
tableCell.ColumnSpan = 3;
gridViewRow.Cells.Add(tableCell);
GridView1.Controls[0].Controls.AddAt(0, gridViewRow);
}
}
... There by u get the desired output...

Just a note:
The original question was how to merge a *DataGridView* Control.
The answer above appears to show how to merge a *GridView* Control.
The two controls are not the same.

Hi All,
I have a datatable with som rows. for example :
activity date time
a 01-01-07 12:00
b 01-01-08 13:00
c 01-01-07 12:00
As you can see, activity a and c have the same date and time. Now i have to filter those rows from the datatable and set them into a textbox. So how can i compare all rows with eachother and if they have the same date and time, then show them in a textbox????
Thanx.

In the RowCreated event of GridView match each row from datatable to that of the time in the new created row. if it matches show it in textbox else leave it as it is. Take care that the activity is not matching.

Hi,
Something like this might do it for ya...
DataRow[] _dataRow1;
DataRow[] _dataRow2;
foreach(DataRow dr1 in whateverYouCalledThis.Rows)
{
_dataRow1 = dsYourDataSet.Tables[0].Select(“date”);
foreach(DataRow dr2 in _dataRow)
{
_dataRow2 = dsYourDataSet.Tables[0].Select(“time”);
}
this.txtDate = _dataRow2[0]["date"].ToString();
this.txtTime = _dataRow2[0]["time"].ToString();
}
I'm sure there are better ways to do this

How can I Disable users not to view the Source Code of Javascript using Internet Explorer ->View->Source at runtime?

I think We cant disable..

Disabling the user from viewing your source? I don't know if that is possible by a remotest way. But, you can surely obfuscate your javascript. Look at the following URL:

oncontextmenu="return false">
The above statement can block the right clicks on the page. Then also the browser has options to view the source. So better try encrypt HTML.

Hi All,
I have a button on my screen that kicks off a long background worker, if the user clicks this button again is it best practice to:
a) inform them that the process is already running in the background
b) disable the button completely
c) just perform a check, if the background worker has started do nothing, if not kick it off ...
Cheers,

Well I think that depends entirely on your application. b) is neat but a) is more informative for stupid users (they're all stupid unless proved otherwise). c) suggests that you don't care whether your users know whether its running or has run at all.
Don't think there's a best practice as such here.
Regards,
Rob Philpott.

Haha!
Indeed ... Your right, after I posted that I was thinking "hang on ... they all have merit ..."
There is loads of feedback in the interfact already showing them that stuff is happening like feeding a count to the interface a progress bar and another label showing them detailed info about what is being processed at any given time ... thing is at the moment they can still hit the button and kick off another background working that will basically just do the work again ...
hmm ... time to protect things methinks!

Hi all
I have 2 classes
Public class DB
{
public dataset select(string Query,string tablename)
{
try
{
//Select logic
}
catch(Exception Ex)
{
throw Ex;
}
}
}
Public class InterActDB
{
public dataset selectQuery(string Query,string tablename)
{
try
{
DB obj = new DB();
obj.select(Query,tablename);
}
catch(Exception Ex)
{
throw ex;
}
}
}
from winform file i create object of InterActDB and anc call selectQuery, if any Exception occured in DB class that can not throw up to Winform try catch .

You will try this...
int result=0;
try
{
DB obj = new DB();
result=obj.select(Query,tablename);
}
catch(Exception ex)
{
throw new Exception(ex.Message);
}
return result;

This is simply awful! You've just lost all relevant information about the exception and instead just passed the message up the chain. At least add something relevant if you want to throw a new exception:
int result=0;<br />
try<br />
{<br />
DB obj = new DB();<br />
result=obj.select(Query,tablename);<br />
}<br />
catch(Exception ex)<br />
{<br />
throw new Exception("Failed to execute Select",ex);<br />
}<br />
return result;

thanks for help could you specify it in my code?

Nothing needs to be added to your code, you use Find in the code trying to find one of your elements. Did you even read the documentation I linked to?
