I have a gridview with paging, which displays 5 records in each page.
How can I sort the elements of the current page only?
And other pages should not be sort?
I am using ASP.NET and C#.NET.
Is there any way to do this in LINQ?
I 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?
I have a datatable as a datasource to a grid view, it has a column amtDue, i would like to be able to sort by this column,, while not displaying it.
View 4 Repliesi had button under gridview
and sending value to another page here i could not get the second row column . It is taking only
1st row column only, check below code

i want to sort my Gridview rows by a template column that is not bound to any database field. This template coulmn just has a label whose text i set in code depending on a value in a different column that is databound. So am stuck on how to set its sortExpression since its not linked to an column.
View 1 RepliesI want to orderby the list. Today date is on the top and then next date and all dates but when today date is passed then it comes on the end of the list. Is there any formal query in linq or some other code is used to achieve this?

but when today is passed then it automatically go to end and next today date is on the top
Just spent about 8 hours googling and looking through this forum for a solution on how to make sure that I can dynamically sort. Here is the situation.
I have 1 Gridview that displays 10 different scenarios based on what button is clicked.
I am also returning only top 10 records. I am doing all of the data binding pragmatically. So I have BoundFields, HyperLinkFields etc.
I also want to sort some records. When I change DataSource SQL statement the gridview somehow remembers what the last sort value was and it errors out saying that value "x" cannot be sorted because it does not exists.
I tried this:
Tried setting gridview1.sqldatasourceid = null; gridview1.allowsorting = false; gridview1.databind();
Here I get an error that says that the data source does not support sorting? Doesnt it say gridview1.allowsorting = false;
I also tried gridview1.sort("", SortDirection.Ascending); This does nothin... except query my database one more time because i have a onSorting event that looks like this:

View 3 RepliesI have a simple dynamic gridview with following code -
GV = new GridView();
I seem to be running into an issue where my Grid-view doesn't display any rows when the number of items is less the page size (in this case 10), I'm using the object data source and at times it can return 1 or 7 for the number of items function call, which cause the grid view to not display anything at all. If I change the page size to 1 or 7 then the results will show.
View 1 RepliesI have a gridview with data. I want a button which is not part of the gridview. Then if I press a button the gridview is sorted by two colums. i.e column1 ascending column2 descending.
I am not looking to work with a Sqldatasource as I use a data access layer. So the sort would have to be from a datatable and databind or directly with the gridview.
Actually i want to ask which is the best for sorting in Asp.Net is it DataView.Sort Method or List<Object>.Sort() method.
View 1 RepliesI'm looking for a way to sort the rows of a datatable without setting the DefaultView.Sort to a specific column. I have a datatable in session that users can add records to. I want them to be able to sort the data by clicking on a button. But new records added after that need to show up at the bottom of the list until the sort button is clicked again.
View 2 RepliesI've got a Varchar2 field in my table which I want to convert to a CLOB. I am unsure whether the data would get truncated when selected. If so, what is the limit and does it depend on the database settings?
In my TOAD or SQLPLUS window it gets truncated but this may just be the environment settings. I'm not sure whether it would get truncated in my actual application (I can test this, but up to what size should I test?)
If it does get truncated, what's the best way to display the whole CLOB? There are other fields in my SELECT query, so I think I can't just loop through multiple rows. Is there any way out?
I have a gridview in an updatepanel with sorting enabled and an event handler as follows:
protected void MyGridSort(object sender, GridViewSortEventArgs e)
{
var TheDirection = (e.SortDirection).ToString();
var TheColumn = (e.SortExpression).ToString();
I put a breakpoint just after these lines. Every time I press the column header, my variable TheDirection is always showing Ascending. Why is it not toggling from ascending to descending and back?
What's the best way to do this? I have seen quite a few examples that use a Dataview etc. what is the best method. I'm thinking about speed issues when a grid has a few thousand records etc.
this is how I populate the gridview:

I have a repository that contains all of my LINQ queries for this project that I am working on. I am able to get the LINQ results to a DataTable and bind that to a gridview for displaying the data. Now I need to make the gridview sortable. I have set AllowSorting="true" and I have the OnSort event handled in a routine in the codebehind.
View 2 Repliesthe specific example i am referring to is this site [URL] notice the sort by drop down list. basically i want to sort products according to price,name,popularity? do i have to requery the database and retreive the sorted data in gridview again, or should i already sort the items in the gridview that are already there? I tried to this but its the wrong approach, basically i was trying to repopulate data in the page load event, which was giving error.
