Can a gridview contain an image and text in the same column?


I have a 1-column gridview (and it must remain 1-column) which contains only text.  My requirement is to prefix each row with an image followed by the text.  The image may or may not be indented a bit, like an expanded child node in a tree.

I know a gridview renders as a table and I know I could put an image at the beginning of each row in a table (using a repeater, for example).  But this is an existing app with a couple gridviews which need to be enhanced and I don't have the time to swap out the gridviews for repeaters.

I can't find any reference anywhere on the 'net which deals with this topic.  Anyone have any ideas?

Thanks in advance,

Changing the binding for a GridView column



I have a gridview bound to a SQL Select statement. I want the binding of one of the columns to depend on one of the values in the database record. For example, say I have a SQL table containing FirstName, LastName, ShowFirstName. 

I want a the Name column in my Gridview to be bound to FirstName if ShowFirstName is 1, and bound to LastName if ShowFirst Name is 0.

What's the easiest way to do that?




Tooltip for GridView Column Headers (ASP.Net)

I just wanted to add auto tooltips for my GridView headers. There are couple of ways but I don't want to use javascript and wanted to use simple 'title' attribute. It took couple of hours to get the working code supporting sortable columns. I thought it will be very useful for others. Here's the code and logic behind it.

Use a column as parameter for a sds in another column; gridview


Hola, I have a gridview which is bound to a sds which returns 7 columns and I added two columns from the GUI.  What I want is to fill up the 9th column with DDLs and these  DDLS will get their data from a different sds which is using a stored procedure with a single parameter.  I created the 9th row, used template field, made the sds for 9th row, the stored_procedure, threw a DDL in Item template and all  I need now is to pass a parameter in the first column to the sds in the 9th column.  I can code this but i'm getting tired of aspx.cs :) and would like to do it from the GUI.

Rendering data with HTML tags in the DD Gridview for a selected column


I am having trouble finding out where and how to HTML Encode a cell's data on the Dynamic Data (v4.0) gridview of List.aspx.  As a simple case, suppose I have formatted cell data that is A<br/>B in the DB.    Obviously, I want A stacked on B in the cell.

It seems gridView1.HtmlEncode = true has gone away.

So maybe I'll try to catch it on the RowDataBound event:

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)

            if (e.Row.RowType == DataControlRowType.DataRow)
                // Html Encode the cells


but this event never fires?

Has anyone figured out how to properly render HTML tags data in the List.aspx's GridView1? 

If I figure this out, then I can add a MetaAttribute called something like [EncodeAsHtml(true)] and be on my way.  Thanks!

Unique text value in databse column


Hi Everyone!

I know this is probably a very basic question but how do I keep a column's text values unique in SQL server (ie for a unique username)?  The column is not an integer it's varchar(50), and it's not the primary key but I could make it the primary key if recommended.

The front end could handle it;  where the user would enter text, it's validated, then a query is done to see if that username is available.  If so, then user can decide to choose it and an insert is done, if not they pick a new username and process repeats.  With this approach, the responsibility of keeping the value unique solely rests on the front end, nothing on the database side.

Is this the correct way to handle this? 

Thank you!


gridview tablecell text emptystring in RowDataBound event when editing


HI and thanks in advance.  asp.net using vb, using a codebehind page.

I have a relatively simple gridview bound to an product table that displays great.  The problem comes when I choose to edit a row.  When I do so, the gridviews' RowDataBound event fires and the values of the text properties of the tablecells in the row evaluate to "" emptystring. 

I do notice that if I break within the GridView1_RowDataBound event during a refresh of the page, the values are there.  But again, when I hit the "Edit" button in the first column (the CommandField column) .  Text properties of the cells resolve to ""

 Here is the code for the event, followed by the gridview in the form (inside an updatepanel)

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then  ' not a header, footer row.. etc.
            Dim cellProductNumber As TableCell = e.Row.Cells(3) ' ProductNumber column

'>>>>> after clicking "update", even though a value displays in the gridview,
' the cellProductNumber.Te

Changing a textbox's readonly property right before update on a gridview


I have a gridview with a date field. I don't want the user to be able to type in their own date and mess up the format so I made the property readonly. That date is then set by a point and click interface. This is all working fine but when the user clicks update this field doesn't update because it's readonly. If i turn readonly off it works so is there a way to turn off the readonly property right before submit?

SSIS Changing Column Order during Transformation

First let me say, I really can't believe this chain of events myself--and they are happening to me. I am upgrading several DTS packages to SSIS on what will be my new production server.  These packages create tables, export them to a flat file, and ftp them off to other locations. What is happening (on the SSIS side) is that the OLE DB Source is reordering some of the columns on its own (moving them to the end of the table/file.  Then when my pickup/load routines run, the data is out of place and they fail. Can anyone please explain what is happening here with the mapping.  I have evaluated the table and the columns are in the order that I expect.  When I preview the source table in the OLE DB Source Editor the columns are in the correct order/alignment, but when them in the OLE DB Source Editor --Columns section within BIDS the order is changed arbitrarily. I have been somewhat successful (2 out of 3) in being able to re-map the data, but this last table just doesn't want to change.  Thanks in advance for any help and/or information you can provide

How to read a column of a sharepoint list to a text string field of infopath form?

My infopath form used to read these email addresses from a web service and web.config file. Now i would like to get these user email addresses from a contact list in a sharepoint server. I am trying to do this without writing any codes. Here is what i have done so far: 1. Adding a new "data connection to receive data from SharePoint library or List" where i selected Email Address column of the contact list. 2. I added a new Text Field and define a new rule with "Query using a data connection" defined above. When i try to access the newly created Text field above it always return empty as if the Query attached to it did not executed at all. What did i do wrong? Is there a better way? Thank you in advance for your help.
