I have been struggling with this problem for a long time. Does anyone have any clue about this problem? I created a gridview and set the allowsorting to true. This gridview has four columns: Name, Position, StartDate, and EndDate. I want the gridview to be sorted on the EndDate.
Inside of the save event, I called the BindGrid() function to rebind the datasource to the gridview. The changes will shown immediately, but the problem is that the records are not sorting on EndDate. I have to refresh the page manually to get the view sorted.

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>

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:

i need to sort the gridview based on the radiobuttons. and i have 3 radiobuttons like dept,empcode,reporter..
if i click on any of radiobutton i need to show the gridview by sorting order..
I'm new to ASP.net (and coding in general) and I was very impressed about how easy is to learn enough to create something useful :)
Unfortunately, now I'm stuck on a problem involving gridview sorting and paging: I created a master gridview bound to an sqldatasource, I enabled sorting and paging and then I linked it to a detailsview to enable editing and inserting.
In addition, I set up two other gridviews whose datasources depend on the master gridview.
When a user selects a row and modifies it in the detailsview, the sort takes place and the row is often moved to another page. This can be a little confusing, especially because there are other controls relying on the selected row of the master gridview.
There's a way to find and select the page of the selected row after gridview's databind and sort take place? I tried creating a dataview to search the index of the selected datakey in the databound event of my gridview, but it doesn't work, because it seems that the rows aren't sorted yet. Maybe I should choose another event?
I have the following sorting code that works find when clicking on a column header in a gridview.
Now, I'd like to fire this sorted table & fire it on load instead of having the user have to click a column heading.
how to do that?

how to sort DataGrid column. (Say like FirstName) I have done snippet like: (see Bold text) For HTML :
<asp:DataGrid ID="dtgCustomerSearch" runat="server" AllowSorting="true">
<Columns>
<asp:BoundColumn HeaderText="CustomerID" DataField="CustomerID" />
<asp:BoundColumn HeaderText="First Name" DataField="FirstName"
SortExpression="FirstName" />
<asp:BoundColumn HeaderText="Last Name" DataField="LastName"
SortExpression="LastName" />
<asp:BoundColumn HeaderText="Phone No." DataField="Phone" />
<asp:BoundColumn HeaderText="Email ID" DataField="EmailID" />
</Columns>
</asp:DataGrid>
On Page_load I have wrote: this.dtgCustomerSearch.SortCommand += new DataGridSortCommandEventHandler(dtgCustomerSearch_SortCommand);
private void dtgCustomerSearch_SortCommand(object source, System.Web.UI.WebControls.DataGridSortCommandEventArgs e)
{
SortExpression = e.SortExpression;
BindTheGrid();
}
string SortExpression
{
set
{
if (ViewState["SortExp"] == null || value != ViewState["SortExp"].ToString())
{
ViewState["SortExp"] = value;
}
else
{
ViewState["SortExp"] = value + " DESC";
}
}
get
{
return ViewState["SortExp"] == null ? string.Empty : ViewState["SortExp"].ToString();
}
}

I want to sort with multiple columns.
I have a grid view with manual sorting. In some cells, the data are numeric and datetime. But due to some constrains, the data type on tables are varchar. The problem here is when I sorting those numeric data, it is treated as varchar.Eg: 1, 12, 13, 2, 23, 3, ...But I wanted the order to be: 1, 2, 3, 12, 13, 23, ...I have tried these method, but it doesnt works.

View 4 RepliesI have a gridview, getting data from sql server, there is an Edit link to get the detailed information for example, for a user from database.
this link open a new page with detailed information and when I click the updated button,I want to go back to the same page with that users informaton.
I set the page size to 10, it means I can see only 10 users per page,and if I click the edit link on page 25,and update the users info, I want to go back to page 25.
Should I use viewstate or gridview has any commnad to go back to the same page? the code is written in ASP.net C# sqlserver,
I have a gridview with paging. So for instance, I'm on say the page number 10, and I open the form details on a specific record_id (link). After I update/submit the form, it returns to page number 10. But, if I go to another page, for instance page 5, and submit the form, it returns to page 10.
I've tried some things, for instance history.back(), but it returns to the first page I went to, in this case page number 10 (or whatever the first page I go to).

I have a gridview bound to a sqldatasource with editing enabled. If I click Edit, then either Cancel or Update, the update or cancel occurs and the Edit button reappears. However, I cannot then click the browser's back button without having the Update and Cancel buttons reappear. A second click of the back button takes me to a state where the Edit button shows again, *then* another back button click will take me to the referring page (the one before the one with the gridview on it.) IOW, it looks like the postbacks are cached. How can I prevent this and have the back button go straight to the referring page?
View 4 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.
i read Matt Berseth article also i downloaded this source. But i can not do sorting event. Everything is ok but sorting is not working.

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.
