...Searching all columns without using column name
I am developing a search engine for my application and I need to grab the entire row from the table if I found the search field in any of the columns and the search is not defined to one table. Please let me know how to search all columns in table without using column names indivdually.
If the data is in a DataSet, you can access rows and columns using indexes:
will get the first row, first column. .Rows and .Columns have a .Count property that can allow you to get all columns and rows:

I'm working with PB 5.0.04 on Win 95.
I have a datawindow object which I want to use as dddw. This datawindow object
retrieves a numeric ID and three string fields from a table. I created a
(named) computed field in the detail band which consists of a concattenation of
the three string fields. I'm not allowed to use a SQL computed column.
When I use this datawindow object as dddw with the computed column as
display-item and the ID as data-item I can't store the (main) datawindow. I get
a "syntax error at line ## in column ##" ...??

win2k / pb8.01
When I forget to enter a required value on a dw, I get a MessageBox like
Required value missing for COLUMN NAME on row N
Please enter a value
For legacy reasons my column name is called lineval and can't be changed
I have set a column label in the datawindow painter to "Line Value" which
would look a lot nicer in an error message.
Is there anyway to specify in the dw to use the column label instead of the
column name in the error message ?
Well that's not a PB-generated error, so it must be in your code somewhere...Using the column value of another row in computed column.
Hi fellow PBer's,
I am having trouble figuring out how to reference the column value of a specific
row. In the computed columns property sheet, I select the "More" button to
modify the columns expression. The way I understand help is to specify
columnname[integer] where integer is the number of rows (positive or negative)
relative to the current row (ie Total[-1] would be the value of the Total column
in the previous row. However, I cant seem to get this to compile in the modify
expression painter. I am using PB5.0 on Win95. Any help would be greatly

Greetings,I have several GridViews all showing different collections of similar product data. Due to changes in codes used to distinguish properties such as color and size, I'm having to write several rules into the row databound events. The issue I'm having is that the group who will be using the application haven't finalized the order of the columns, so everytime I reorder the columns, I have to changes all the column indexes in my code behind so that the rules are being applied to the right columns.

I have several extremely similar datawindows that I have to maintain that go
against the same table. Recently, I had to add a column to that table, and
also add the column to ALL of these datawindows that go against this table.
I added the column to the first datawindow, set up the edit control style,
etc. I then did a copy/paste of the columns edit control to the remaining
dw's (of course remembering to first add the column in SQL). Everything
(update props, column specs, column props) seems to indicate that the pasted
column is linked to the column I selected, HOWEVER, when I...Hiding columns in the ItemDataBound event without using the column index
Lately I've needed to hide certain columns in DataGrids depending on the specific data source so I create a property at the top of the page like so:
private string DisplayProjDesc
//DisplayProjDesc property - for ItemDataBound event of the DataGrids to determine whether to display project description
this.lblBoolDispProjDesc.Text = value;
}Then, in the ItemDataBound event of the DatGrid, I use something like:

I need to retrieve a column from my database but do not want to display it in the gridview. However, I need to be able to show that information later in the application. I am using the wizard control. I believe I can use the DataKeyValues property of the gridview but can't figure out how to write the code to get the value of the cell in that column when the row is selected so it can be referenced later. I am using VB. Thanks for your help!!
Found the answer. Here it is in case anyone else needs it:
&nbs...Cannot delete columns of GridView by using "Edit Columns..."
I have a GridView with quite a few auto-generated fields. When I go to GridView Tasks to use "Edit Columns..." to delete a few columns, the design window shows the columns removed just as expected. However, the source code does not change at all. If I save the .aspx file and reopen it, it shows all the deleted columns like nothing has changed. I can go to the source code to delete the fields and the deletion will stay. I am using VS 2008 standard edition.
Could anyone shed some light on this?
