Forms Data Controls :: Sort An Unbound DataGridView By Numeric Or Date Value?
Aug 16, 2010
I'm new to DataGridViews. I have successfully created an unbound DataGridView that contains columns of string, numeric and date values, but I can't seem to figure out how to define a column as a numeric or date value--only strings. I have enabled sort on the columns so the user can click on any column to sort by that column. When I click on the numeric column, it sorts like:
12345.56
13.35
1442.22
...
The dates also sort as strings rather than dates.What is the code to change the data type of an unbound DataGridView column? Is it possible? If not, how can I do this with my unbound data?

Is it possible that once I have created a datatable programatically, I can then sort that datatable before binding it to a asp:repeater? I have a number of records that I have to get from a com object that has not been eliminated. The com object populates an array, then I loop through the array to pull data from my datatbase, adding the db data to the datatable. Then I bind the datatable to a repeater.
1) the array is multidimensional
2) The COM object doesn't sort the data by company ID (which is what I need to do)

I have created a class file which gets me the state codes,license numbers and the expiration dates for the same.
I fetch the expiration dates in string format.
Each customer can have many licenses.
I have changed the format of the date (initially appearing as YYYY/MM/DD 00:00:00 when retrieved from database) to MM/DD/YYYY.
After retrieving all the licenses pertaining to a single customer, I bind them to a datalist.
Now the requirement is that for each customer, I need to sort the licenses according to the latest expiration date and then display the same.
How can this be achieved ?

I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}
It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.
I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?

I am populating a DataTable and binding it to a GridView's source.
I have a dropdown box in an itemtemplate in the gridview.
I want the dropdown to have 3 options and depending on what is in a column from row in datatable a specific value will be selected.
I was able to do this when I was binding gridview source by looping through SQL but now I that I am putting the results in a datatable I am not sure how to go about it.

I have some template columns that have multiple textboxes in them.
There is one textbox for the Date portion of a datetime field and another textbox for the Time portion of the datetime field.
How do I populate those textboxes after the user clicks on the "Edit" button?
My assumption was I could get the data from the label that was displaying the datetime field data, break it down into Date and Time, and then access the textboxes.text property to fill those.
I can get the data from the label control, but when trying to fill the two textboxes with the data, I get Object Reference Not Set... errors.
Im assuming maybe those textboxes are not setup yet during the RowEditing Event?

i use a gridview to show data from datasource, but i have some column in this gridview that they're not bound. If i go in edit mode, my unbound control show me the textbox to enter value and its ok, but if i modify value thru rowdatabound, now when i go in edit mode, the textbox are not showing as i expect, its just showing the value i put in rowdatabound, but i don't have the textbox to let me enter a new value and update it after.
And more in the same relation: with the two above condition i wrote, when i dont modify value in rowdatabound, i can modify value in prerender event with this line:
TextBox
box1 = this.GridView1.Rows[this.GridView1.EditIndex].FindControl("TextBox1")
as
TextBox;
box1.Text = "a value"
;
but
when again i modify value in rowdatabound, the line above will not work too, box1 is load with a null value

I think it's very simple but i just don't see it at this point: I have a detailsview that's bound to a sqldatasource. I want to have access to the data in a field in the table thats not currenty bound/used in the detailsview. I have a table which has one collumn that contains a username of the user who submitted the record. This field is not bound in the detailsview.I want to have the detailsview show delete/edit buttons only if the current identity matches the value in this collumn of the currently bound record. But i don't want to show this field as a row in the detailsview. I thought maybe i can access this field in the databound event of the dview and create/show the buttons here. But how can a access this data if it's not used in a dview field? I also tried creating a templatefield for this field and set it to visible = false. But then i also can't access the data it seems.

I have a gridview control bound to a sqldatasource in c#. In the rowdatabound event I look at a value in a cell and use a function to evaluate the value and depending on that value I populate an added unbound column in my bound datagrid to show an excalmation point. I now want to sort by the column with the excalmation point.

The Datalist is being databound via an ObjectDataSource and everything here works fine. I have a label which I've added to my datalist and it's unbound to anything. Depending on the message information, I want this unbound label to display a certain phrase but it has to be next to a bound label. But if I try to change the text of the label in the code-behind, VS2k8 reports that the label is not declared. How do I do this?

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:

Here is an example of just one of those SLQ statements inside GetSQLQuery:
