I have a GridView, and I want Column1 to be equal to datatable data (filled by a SqlDataAdapter). Then I have two other fields by the SqlDataAdapter (first name, last name), and I want to have those two fields combined to form Column2. I have a TemplateField for my GridView that combines the first name and last name with Eval()'s, but the GridView places this combined field TemplateField and puts it as the first column.
How can I do this so that TemplateField can go in between fields that are databound?
I am using TempleteFields for all columns in my GridView. In that columns I am using only some fields for customization but not all.
Is there any performance issue with Databound Fields vs Templete Fields in a GridView...?
Do I need to replace the remaining columns with Databound Columns instead of TempletField columns...?
I don't understand why my Findcontrol on a selected row is not working. The only thing I can figure is because I put the Select button in an "edit row"???

I have a datatable with the following column names

TPM, PM 10, PM 2.5, B(a)p

When i bind data to this grid view, i get an error saying column "PM 2" was not found. For some reason, the program is dropping the .5 from the column name. I am exploring the possibility of replacing the number with alphabets only but this may not be possible as the end user may not find it user friendly. Is there a way for me to get around this problem? I get a similar problem with B(a)p, it drops everything after the B. Any ideas on how to get the gridview to bind column names with special chars in it?
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.

I have a gridview that is populating from a SQL DB and working fine. However, based upon certain data I find in fields in the SQL table, I want to place a 'n' or a 'y' in extra columns in the gridview that I am assuming need to be templatefields. My thought was I could maybe add 8 template columns and then I could put a 'y' in the appropriate column based upon the data I find the table. For the life of me, I cannot figure out how to do this. I want to do this at rowdatabound time ( i think) but I just cannot find out how to, in my code, put that 'y' in the columns. Is this the right way to do this or do I need to do it another way? How do I get that 'y' in the proper column?

I want to get data from the database and display it in gridview. The gridview should be editable. Meaning the user can add, edit and delete items/rows in the gridview. Everytime the user adds/updates/deletes an item, the gridview is also updated. However, these changes will only be saved to the database once the Save button is clicked.
View 3 RepliesI have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?

View 1 RepliesI have seen a number of posts on this, but none that quite serve my needs. I have a GridView with template fields. I use postback because when a value is entered in one field a calculation is done to supply the value in another field. I simply loop through all the rows after each postback (there are not many so it is fast). I do not use a select command or button to select a row. After postback I do not know how to return the focus to the row that was being used. I can return the focus to the first row just by using gridview1.focus.

My gridview displays fields from a table and allows for edit, delete and insert. I need to add a column with a derived field which will be calculated every time the user is either entering a new row or editing the value of the weight field which is one of the fields of the gridview. This calculation is done in the fly and won't be saved in the database.
