When I click on my GridView header "End Time" all the rows which contain the string "N/A" disappear.
Here is my code:
[Code]....
Note: GetSortDirection returns "endTime ASC" or "endTime DESC" and save in ViewState:

Then I fill the DataAdapter and use the ViewState info to sort it:

I have a page with a TextBox, a Button, a GridView, and a SqlDataSource. I click the Button to execute the SQL in the TextBox using the SqlDataSource. The SqlDataSource populates the GridView. Everything works as expected until I click a column heading to sort.
When I click a column heading, the GridView disappears and I have to click the Button to display the grid again. When I do, the grid is displayed in the order of the column I clicked.
I don't understand why the GridView is disappearing when I click a column header.
Does anyone know how to fix this so the GridView is sorted and displayed only by clicking the column header?

I have several grid views indide div's, and when I click the Sort header on an open div the div collapses and no sort happens. I believe it is just reloading the entire page but when I surround PageLoad with !ISPostBack then the page redraws as blank. Since the sort script is generated by the GV, I don't know how to stop it from creating side effects.
Here's my code:
<script type="text/javascript" language="javascript">
function toggleDisplay(id) {
var obj = document.getElementById(id);
obj.style.display = (obj.style.display == "none") ? "" : "none";
return false; // cancel the href
}
</script>

I need to sort the gridview values when I click in the title of each colum.
View 2 RepliesIs this a good method for displaying a soricon? or are there better ways of doing it;

Also when the gridview is first loaded its sorted by a "Date Submitted" field which is sorted on the data source (stored procedure) is there any way of showing the icon then so people know that it is sorted by "Date Submitted" at the moment the icon only shows when someone re-sorts the grid.
I have a simple dynamic gridview with following code -
GV = new GridView();
AllowSoting is true on every column of my gridvieww.

how can i do that?
I have a GridView in MultiView and everything works fine. When page load everything looks good,but then when i try to edit something in my gridview it does postback and the whole gridview disappear from the multiview.

View 5 RepliesJust 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:

how to display a header of gridvew as a 3D view color Header?
View 14 RepliesScenario:
I have a Gridview where I want to handle the Sorting in a custom control that I've added to the header.
I've added this control to my GridView's Header via OnRowCreate event handling. I want the Sort Expressions to persist session to session (via Webparts Personalization)
Here is what I have for adding the custom header control to the GridView Header
[Code]....
This works out well for adding the control, but I can't get anything to persist because these controls are creating initially via postback (per the event) and re-created on all subsequent postbacks. I can't add an If(!IsPostback) because the controls are initially created on the gridview's postback (well at least thats how it's acting when I put it in there) If I were to add this control via the ASP page, not via the Codebehind, I would be able to persist the control. If I try to treat it as though everything is setup correctly, and assign my custom control's controls to [Personalizable], I get a runtime error telling me that I can only have webpartzones in or before Page_init (I'm guessing this is due to when/where the
gridview hits the OnRowCreate event). If there is some fundimental logic I'm missing, or best practices that I'm moving away from,
is there anyway i can add in the gridview in header column name a button instead of label ?
column name 1 column name 2 column name 3 button
i am using checkbox column in item template for the button ,i wish after selecting checkbox for some row to click on the button on the header !!
I am using the following code to change the header based on the session variable

I have a gridview in which i have declared one static templatefield (with some button ctrls inside) in design itself.
I add the remaining columns to it as a dynamic templatefield by inheriting the ITemplate interface.
My problem is that now when i cause some postback for the firsttime after the Gridview is bounded, it works fine. But when i cause some postback for the second time, all the controls in the static templatefield disappears.
below is my code

I have a checkbox column in a Gridview that is added in the aspx and the other columns are added in the code behind. The checkbox is a choice to print the record or not. When the print button is pushed the page posts back and the checkboxes are gone.
I have read that you have to re-add the checkboxes on postback, but where do you do that and how do you retain the viewstate values - checked/not checked? I have tried everywhere - PreInit, PreLoad, PreRender... I can't get the viewstate values to appear anywhere. The checkboxes can be added just about anywhere but the vaules are set to "unchecked" by default... no values ever come back no matter where I re-add them.
I already implemented the dynamic templatefield which will re-created in every postback. Everytime I make a postback in the page I see no problem but when I click my imagebutton inside the gridview then the dynamic templatefield disappear.
To double check if it is really gone at all I just select the second page of the gridview using my customize paging using dropdownlist outside the gridview and the templatefield with its correct data reappear again.
I already put a variable inside the rowcommand to see if the number of columns are the same with the number of columns the gridview render together with the dynamic templatefield during debugging and it is there but cannot render that templatefield in the client.
I am using gridview to display some columns with autogenerate column as 'true' and not added boundfields,headers.
And i am used stored preocedure for data source in gridview and i used dataset for gridview databind.
The gridview columns comes dynamically for each time.

I am trying to put the select command in code behind:
sdsAdd.SelectCommand = String.Format("SELECT Classes.ClassId, Committed, CallNumber, SubjectArea, CourseNumber, SectionNumber, GradingBasis, NumberOfUnits, NetId FROM Classes INNER JOIN EnrollmentAdjustmentClasses ON EnrollmentAdjustmentClasses.ClassId=Classes.ClassId
WHERE AllFormsId='4' AND SectionId='1' AND NetId=@NetId AND Committed='True' AND EnrollmentAdjustmentClasses.FormId={0}", Request.QueryString["FormId"].ToInteger32());
gvAdd.DataBind();
When I do that, then click edit to edit the selected item, the item disappears from my gvadd. What am I doing wrong?

I have a GridView attached to an ObjectDataSource (returning a DataTable) in a UserControl. The code is really simple. Data comes down fine when the page is first rendered. When I click on Select or Delete (inside TemplateFields), RowCommand is supposed to fire but it doesn't, the page goes straight to Page_Load. I literally have 0 other event handlers that are set on this control and everything else in the codebehind shouldn't even fire if it's a postback. Also on postback, the Select and Delete buttons disappear. It looks like the TemplateFields are still there but they're empty. The data fields (all of two columns) post back fine.
