Re: How can display 10 rows in a datagrid with no values ? [modified]

Hi,

Check if your datasource has more than zero rows.
If no then add 10 rows manually to the datasource with blank data and then bind your datagrid to the datasource.

Thanks and Regards,

I presume that you are binding the datagrid using a datatable. If no data is present in the datatable, add 10 rows manually and bind that to grid.

There is no easy way to do this as the server cannot push data to the browser. You would have to either refresh a page often to check if an event is coming up or use Ajax to check. Of course all this depends on the user having the browser open (and you can't force to browser to take focus on the desktop).

What about writing a small app, that displays a pop-up reminder, that subscribes to a web service?

Theres no reliable way to get this information short of testing the connection. Obviously you'll get a different answer every time so you'd have to get an average some how. In short, its tricky and if its just for a progress bar don't bother (I don't see any way you could get it to work in this scenario anyway)

Help with a paging problem & checkbox selections with GridView (C# asp.net)

I have quite a complicated problem with the above. I will do my best to explain, although I have a word doc (size 149KB) with the problem explained full with screen shots if any kind person would like me to email this link too I can do...

My Grid View consists of 4 cols:-

1 - ItemTemplate (checkbox)
2 - imageField
3 - ItemTemplate (linkbutton)
4 - ImageField

The data that Im binding too consist of nearly 1000 items and I have paging switched on Pagesize = 200.

Once a user selects an item from the grid, this info is passed to another page.
There are 3 ways in which a user can do this:-

1 -The user clicks col 3 (linkbutton) then col 1 (check box) becomes automatically ticked and the details are passed to another page. This is working fine

2 - The user clicks two checkboxes (col 1) and then clicks col 3 (linkbutton) , but because two other check boxes are already selected and the user has clicked the ‘Col 3’ of one of those items selected, the details of BOTH selected items are passed to another page. This is working fine

3 - This is where I need help If a user clicks on Col 3 (linkButton) and 'other checkboxes' have been ticked (but of different rows to the one which the LinkButton is one) I need to unselect all of the selected check boxes & then auto select the checkbox associated with the clicked linkbutton, then details of this single selected row are then passed to another page. My problem is that some of the checkboxes I have to unselect maybe on different page

If anyone actually understands what I’m trying to do ?! Any help would be most appreciated.

Many thanks,
Janet

Hi,

You should loop through all the rows of Gridview and find checkbox inside it and uncheck that checkbox in your code.

foreach ( GridViewRow r in gv.Rows )
{
CheckBox chk = ( CheckBox )r.FindControl( "chkid" );
if ( chk.Checked )
{
chk.Checked = false;
}
}

Now the question comes of the checkboxes on the different page of gridview.

That I think u dont need to worry about if u r not maintaining their values during postback.

If u r doing so then you shoul remove all the values from there except the one which u want to keep.

I hope this will help u.

Thanks and Regards,

how to print an excel file?

19-Jun-07 1:07

Hi,

You can do this by following.

tbl1.Rows[rowindex].Attributes["class"] = "cssclassname";

here "tbl1" is the id of your HTMLTable and "rowindex" is the index of row in that table.

I hope this will help you.
