In my application I am sorting the gridview and also have Edit in that gridview, sorting works fine but when i click Edit, it puts the gridview in the original sorted order. when i click Edit - it lets me edit the row but it changes the order and show me the original record on that row in the edit mode.
below is my code:
protected void GridDispatchshow_RowEditing(object sender, GridViewEditEventArgs e) {
GridDispatchshow.EditIndex = e.NewEditIndex;
Label lblpblm = (Label)GridDispatchshow.Rows[e.NewEditIndex].Cells[10].FindControl("lblproblemfaced");

I have a grid view which populates data just for viewing purpose(report) . One field shows the Active/inactive status for which I am showing a checkbox..if data in database is 1 then the checkbox will be checked otherwise it'll not be checked. This field is inactive so that the User does not check/uncheck it. The issue is that this field cannot be sorted. All the fields in the gridview are being sorted.

Moderators Note: THIS ISSUE IS BIG FOR ME AND EVEN IF POSSIBLE, GET THE REPLY FROM THE DESIGNER OF GRIDVIEW. I have been looking for him for long. I am really fed up with reviewing a good lot of web pages on how we can possibly customize the gridview to enable sorting and paging. So many sites have listed out a lot of information and so many guidances. But the problem is that one works out fine and the other is a burden. I really feel bad about being given the job of customizing this kind of a gridview which has no user friendly approach to it. Also, this control is rendered without the pager links inside the <tfoot> tag. I have tried the Pear Pager in php. It is that good and easy to use and compared to that, the gridview in asp.net is the worst ever control i have ever tried so far.
1. i can use the images to indicate the sorting direction
2. I can have the custom pager like
[code]
<<Previous 1 2 3 .. 7 Next >>.
[/code]
When i click the next when i am viewing the page at 3 , the pager links should change as
[code]
<<Previous 2 3 4 .. 7 Next >>
[/code]
Kindly look into this type of requirement and firstly tell me whether this is possible with the gridview control. I would like this request even to be escalated to the designers of the gridview control also, so that Microsoft comes out with a reply THAT WORKS and not the kind of stuff like surfing through a lot of links and pages and finally wasting a lot of days precious time and still breaking the head with this useless control. I have spent a lot of time in searching for a perfect way. Not writing a code that is non-standard. I am really serious b'cos I have spent weeks in customizing this control. If I dont get a solid reply atleast now, I am going to generate all the output by HTML content by custom coding.

although i had to take the table that has my calculated column and make a view (so i could filter) and then bind the gridview to the view.
My question is as this.
1.) in order to get my calculated field i had to load my data into a table (as suggested)
2.)Add a column to the table and perform calculations
3.)make a dataview from the tables because i could not get the Gridview.datasource= ds.tables("loads").select("Deadhead <= " & sngRadius
4.)the largest of the 3 tables my query is based on contains about 7000 records. The way i have the logic & programming now everytime a new "truck location" is put in the textbox1 and "find loads/button1" is clicked. It calculates the deadhead miles of all 7000 records before filtering. I am filtering based on the deadhead miles.
Does anyone have any recomendation about how to speed this up a bit.
Also in order to get paging to work i had to rebind/filter the data again ... means looping through all 7000 records each time paging is called. This seems terribly ineffecient as i am already forced to use access instead of SQL.
Would i see a performance increase if i installed SQL or mySQL and create linked tables to the ones i use in access. or would access still be the bottleneck?
I don't know if the performance increase would be negligible as i still ultimately be getting the data from Access.
I have posted the entire code for the page below. When i originally started i didn't think there would be to much code so i left it all on one page instead of using code-behind. Would i gain anything by swapping to code-behind now?

I go this code that can so a manual sorting on grid view. The code works fine for "ASC", when I wanted to sort the field to DESC, it never works. Second, it also failed when I switch to another page. Case 1: By default, the column is sorted DESC, then I switch to ASC, works fine, then I switch to DESC, it failed (remain at ASC).Case 2: By default, the column is sorted DESC, then I switch to ASC, works fine, then I switch to other page, it failed (remain at DESC on new page).

I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:

I got a web page, it has a tabcontainer, within each tab, there will be a gridview, all the tabs and gridview are created at run-time, i have only one code, that I will loop through to create all those tabs and gridview. When I apply the sorting, and I click on the column name on any grid, it returned an error saying index was out of bound. BUT, when there is only ONE grid view created, it is working fine, I suspect it mixed up all the grid view's id and so on. But I have assigned different ID to gridview
View 8 RepliesI have a gridview which has editable columns.
The gridview lives in a formview, which lives in another formview.
Inside one column is an end date. This column has a textbox which gets it's value when I choose a date from a calendar control. However, when I choose a date from the calendar control, the program crashes instead of populating the text box.

that aspx page contains gridview that contain one more gridview inside in it.Now i want to sort out both the grid i.e)claimgrid and Gdclmline1 i want code in c#.
I'm trying to extend the GridView control to enable sorting and paging for any situation.
When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach?
To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView.
Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView.
My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable.
The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below,
[Code]....
I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.
I have a databound gridview using datatable as datasource. Template fields are used to edit the row content.This cell value should get updated in the datatable on text_changed event without using gridView edit. Is it possible to overload the GridViewEditEventHandler for this purpose.
View 3 RepliesI ahve displayed a group of data in my gridvew with the edit option linkbutton template field for each row. The gridview columns consist of employee name and projectname and total hours field employee worked.
So in this when i click the edit button using the datakeynames alue for project name id and employee id ,i have to redirect the page to another page with the values in the grid for the particular employee.so that i can update the totalhours field in the redirected page.and if i press the update button in that page then the page should be redirected to the gridview page with the updated value for the particular employee and project. The page which should be redirected consist of project name dropdownlist, module field,date field and total hours field. No employee name field.
Using the gridview rowdatabound field i have postbacked the url page with the project name id but it does not displays the project in the redirected page.And employee name i have to redirect with the session value i think?
