I have one big DataTable with X rows. I want to select Y rows from it and bind them to a new ViewList. While doing it, I want to delete these rows from the DataTable (Having X - Y rows).
What is the best and fast way to do it?
I don't know if it is better to create a new DataTable to have the Y and after that bind them to a ViewList or something else?
I'm also looking for example in code how to select/delete rows from DataTable.
I came across a situation where a user selects no of rows from dropdown , depending upon the user input, automatically that no of editable rows should appear to input data...(maximum 8 rows only)
View 1 RepliesI have a gridview which right now is getting loaded with four pages of data. There are 50 rows per page. My problem is I need the "select all" button on my page to select 180 rows, not just the 50 on the page. This is my javascript:
Code:
function sel() {
var frm = document.forms[0];
isSelected = !isSelected;
for (var i = 0; i < frm.elements.length; i++) {
var e = frm.elements[i];
if (e.type == 'checkbox' && e.name.indexOf("ckSelected") > -1)
e.checked = isSelected;
}
}
I am more a C# person than javascript, but I am deducing that I need something other than document.forms[0] to represent the entire gridview. Or perhaps, I can't do this in javascript at all. Do I need server code to run and set a session variable, then when the user clicks the button to do something with all his selected rows (it goes to a detail page), query that session variable to see if it's all rows instead of iterating through each gridview row individually to see if the checkbox is checked?

id like to display the lowest column value there is, but if there are multiple rows with the same (and lowest) value id like it to be random which one of the rows is selected.. how would i do this? my select statement is currently:
SELECT TOP (1) url, ABS(r1 - @r1) + ABS(r2 - @r2) AS difference

If I change the page size to 1 or 7 then the results will show.

i am using the inbuilt database in VS08. I was trying to write code to query Gridview control to show only those rows whom i specify through my Query.
I searched for it and found some code which might work for External databases. But found no code for inbuilt database MS SQL Server provided in VS08.
Also there is no such method available for GridView1 object.

I was thinking of using Regex to do this, by replacing the * with regex for any character. But am unsure as to what the SQL or LINQ code should be for the selection.
