Forms Data Controls :: Databound Fields Vs Templete Fields In A GridView?

Aug 18, 2010

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...?

Forms Data Controls :: GridView - Putting TemplateField Fields In Data Bound Fields?

Sep 26, 2010

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?

Forms Data Controls :: GridView And Focus / Have A GridView With Template Fields?

Apr 27, 2010

I 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.

Forms Data Controls :: How To Add Calculated Fields On A Gridview

Jul 21, 2010

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.

Forms Data Controls :: Null Fields After Update In Gridview?

Apr 13, 2010

I have a Gridview showing the data on one of my tables, and when I try to edit the data in one of the columns after I click update, rather than updating the record with the new value I typed in, the rows become null as in, everything in the row I just edited disappears. This inmediatly makes my application crash because one of the fields in my table (IssueDescription) doesn't allows null values.

This is the code, which is actually 100% auto-generated from when I created the GridView control and specified in the options to implement update, delete, edit options.

<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AutoGenerateColumns="False" DataKeyNames="ticketNum"
DataSourceID="SqlDataSource1" [code].....

What is making the rows turn into null after the update? I did some research and tried to define the Update behaviour myself using RowUpdating function. After hours of learning how to use it I got it to "work", but because the Update turns everything to null when it updates, the sqlconnection command I use to do the query sends null anyways. I can paste the C# code if you'd like to see it, though I'd rather not use it if the auto-generated by asp above can be fixed instead.

Forms Data Controls :: Customizing The Appearance Of Fields In A Gridview?

Mar 19, 2011

I've got a gridiew with I've bound data to using a linq query as a datasource.The issue I have now is that I'm not sure how i can go about adjusting the appearance of the results in the fields.For example, if I want to turn the results in field 1 into a hyperlink (per record, e.g. record 1's hyperlink would point to url "x" and record's hyperlink 2 would point to url "y") which points to a location determined by a db query based on the record's value, how can I do that?And how would I go about adding columns that aren't present in the results, like a checkbox for each record?I suppose the stumbling block for me is that when using a linq query as a datasource, I am not presented with a layout of any kind in the aspx page, unless I use a linqtoSQL datasource (Which I would rather not use as I can't use complex queries with it....can I?

Forms Data Controls :: Display Data From This Table In A Gridview Using Template Fields

Oct 26, 2010

I have a datatable with the following column names

ProviceID, ProvinceName, Year,
TPM, PM 10, PM 2.5, B(a)p

I'm trying to display data from this table in a gridview using template fields. Here's an example of a label in my item template

[Code]....

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?

Forms Data Controls :: Dynamically Populating Fields In A Gridview Depending On Data In A Table?

Jul 17, 2010

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?

Forms Data Controls :: Edits In GridView Not Working For 'Text' Fields?

Oct 29, 2010

I'm using Visual Web Developer 2010 against SQL Server 2008 R2.

I have a number of GridViews and FormViews working now, with edit functionality. However I have one field in my main database table that is of type 'Text'. With that one field, the edits won't take. I click Edit, change the text in the GridView, and click Update, but it just reverts back to the unchanged text.

It seems like I've tried everything. Is there a way to make that work without having to code it the hard way with a Textarea control?

Forms Data Controls :: Way To Manually Setting Up Gridview Fields And Sorting Using Datatable

Mar 20, 2011

I have a need to call Oracle stored procs to populate a gridview. I'm able to call one stored proc to get the column header text and another one to get the corresponding data. Currently I'm using a datareader, but I want my gridview to have sorting and paging enabled, so likely I'll need to read the data into a datatable and then bind the gridview to it.I've never had to manually configure a gridview - usually just use autoformatting.1. Do I essentially set up the columns manually in the gridview since it has no data to go off of in design mode? I'm guessing most of these will be Bound fields. A few of my columns are going to display date values that need to be formatted a certain way
and one column will be a link that needs to call a second method to populate a different grid. I'm not sure what the syntax for this is.
