I have a gridview that loads with a new datasource on button click event. On the gridview (which is located in a table columm incidentally) are 2 columns, a descriptor and a checkbox. The problem is that after postback, the column widths change, the checkbox column expands and the other column contracts. Is there a way to keep the gridview column sizes the same after postback?

Basically, what I want to do is to get all my data in 1 statement and then pull data from that into a GridView. I already have the columns that I want displaying in the GridView, but now I want to insert a footer row in between the header row and all the datarows, that contains a couple columns that will be the same for every row in the GridView. So something along the lines of this:
Header1 Header2 Header3
Dept: Technology
data1 data2 data3
data4 data5 data6
data7 data8 data9
The thing is, I don't know what that "Dept" will be, so I want to pull it from my SqlDataSource that already has it.
I have been looking at this article: [URL] However, I have a question: Can't this be used with a sqldatasource, instead of binding the gridview behind? If so, how?

I have a gridview that needs to be generated from code behind. There is a column with a name field and the remaining columns give the different user-ids linked to that id. Like this:
-- NAME, ID1, ID2, ID3......
The Name column will be populated from a table that has the Name as well as number of ID's associated with that name. eg [Name1][3]

I'm trying to change one section in code from DataGrid format to GridView format. The reasoning is that the sample application that was displayed was using a DataGrid even though it should have been using a Gridview for 2.0 and above. Most of it shows up without an error except one line in 3 lines which are pretty much the same. I bolded them and just want to know how do I re-write them for the Gridview?

When the data is retrieved through a stored procedure using the SQLDatasource control that is binded to a gridview control, I want to change some data that is in some of the columns. Can i do this in one of the events either in the gridview or data control? I know you can do some formatting on the aspx page side such as dates, etc. but was wondering if I can do it on the vb code side?

View 1 RepliesI have a series of dropdownlists on webform in ASP 4.0. The first drop down is filled upon load, and then when a user selects a value from that list, it populates the second dropdown. To accomplish this, I have a SQLdatasource with a parametersource of the first drop-down list control. This works great, except when a user changes their selection from the first drop down. It performs the query, but then adds the list of items to the ones that were already there from the previous selection, instead of replacing it with the new data. Here is the code:

Do I need to do something on selectedindexchanged to somehow "clear out" the previous datasource? I can't find anything about this online, although one person seemed to suggest it was related to using a master page. (which I am using).
I have a gridview that was quite easy to setup and pull all the reqested database info from an object data source in my BLL. However for the life of me I cannot get any of the columns to change there widths. If I change the columns footer, header, and item style to something around 50px or as large as 5000px it will not change whatsoever. The gridview width as a whole is left blank. Currently I have a phone number column that is the default column size that is overflowing the entire grid. Is there some trick to adjusting column widths in a gridview? It should be as simple as going to the smart tag, editing columns, and changing each ones style to the width I want?

View 5 RepliesI have a dropdownlist as a template item in a gridview - it populates fine and with the right values. I have an SelectedIndexChanged on the dropdownlist, and has set it for postback. In the SelectedIndexChanged event, I would like to know where the control that fired this event is, - which row in the gridview is it in? How do I get this info? If the row was selected it would be easy, but the only thing that has happened in that row is that the dropdown has changed value and consequently the SelectedIndexChanged event has been fired - is that enough to know which row the event has been fired from?
View 1 RepliesI have a Gridview with about 6 templated columns hooked up to SQL, with a Save button below the grid.
When save is clicked, I loop through each row, and write each row back out to SQL.
Can you recommend a good way for me to tell whether the row has changed so I can avoid re-writing the row when nothing has changed?
This is not only for performance, but I also have a request to write out a "Last Modified Date" along with each record. So for that, I would need to know whether the row has changed.
I saw someone mentioned that the Gridview.RowState could be used for this, but I don't see how.
One alternative I see is to re-read each row from the database first, to see if anything changed. Another alternative might be to set a dirty-bit on each Textchanged, SelectedItemChanged, etc, for the row, but I'm not sure where to store that.
I have Gridview which allows user to edit record.I already build the event to save the new record, time and user machine information to a log database.However, this means a whole record is saved to the log... if the user just change one or two column/field out of say 20 fields, then there is a lot of waste. Also the change is not obvious.How can I log exactly which field(s) was changed in the record ?
