I would like to use the trim() method to remove white spaces at the beginning and/or end of text entered in text boxes that are in Insert and Edit Item templates. example with the code below if there is a way to do this?
This is the example of one of my template fields:

I have a sql data souce that returns several columns of data, and they are displayed in a DetailsView on a pretty simple vb.net page. I'm stuggling with one field though for the details view.
It's a template field, and if ClientType=1 (this value is determined else where on the page), then the label in the template field should have Text='<%# Bind("ClientName") %>', but if the ClientType = 0, then the label in the template field should have Text='<%# Bind("ClientTemporaryName") %>'
How do I tell the details view to set the text for ClientName to one or the other?

I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.

I have visual 2010 with net 3.5 web app. I was implementing EntityFramework in my project and added a gridview to a entity source control. It worked ok, with select, update, and delete buttons enabled on the grid. But then, i needed to add a template field bound to a Foreign table, so my users select value from a list instead of writing the code. After that, my app fires error when i delete. I tried everything, inclue dakeyNames, write code on my RowDeleting, RowDeleted, RowCommand, but error persists.
Now, i can delete the row, but it then i get the error Object reference not set to an instance of an object If i implemente delete code on RowCommand i get the error: Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries.

View 1 RepliesI 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?
I understand in a gridview that is databound by default HtmlEncode is set to trueHow do I protect template fields in any data presentation control?
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.

Background: I'm populating lots of asp.net c# GridViews and ListViews from a database and subsequently users may export them to Excel. I want export as native Excel (not html). I can't use office automation, and I'm using JET which works fine. I have no control over users' machines. Question: When doing the export, you have to tell Jet what type each field is, in my case "text" (varchar) or "numeric" (double). The difference is that if you export a numeric column, the users can sum the data in Excel, where as strings are exported with a leading apostrophe and so are not much use in arithmetic.
Currently I parse the first data row of the Grid/ListView, check if each value is numeric or text, and assign a type to the column accordingly. That works, except for when I have something in the first column which looks numeric but in fact is a text string. I don't want to parse every row in order to be sure I have the correct data type as some of these exports are quite large. When I load the Grid/ListView from the database, the database certainly knows what type each field is. So my question is... how do I extract the type of the database item behind a a Grid/ListView item? I could explicitly code it as an attribute on the item, but that's duplicating information I already have, if only I can get to it. I know that where I have a DataTable then I can get the underlying type from that, but mostly I don't have tables handy, just the Grid/ListView. Note that Jet will throw if you try to insert an empty string into a nullable numeric column. The way to do this is to omit that column name from the insert statement, or output a zero.
I'm trying to trim a comma from the end of a string. I've tried the following:
Variable.TrimEnd(',');
I've also tried:
char[] CharToTrim = { ',' };
Variable.TrimEnd(CharToTrim);
Neither option is working. why?
I'm trying to to display the first 50 characters of text from a database field.
I thought I could do it something like this: <%# Eval("BodyTxt").ToString().Trim("50")) %> but it doesn't work.
I've also tried this: <%# Trim(Eval("BodyTxt")) %> although I never expected that to work.
I have a repeater that generates last names. My issue is for the names like Smith, Jr I want to remove the comma and everything after it so that is just displays Smith. I thought the code below would work, but it doesn't.

I am using this command to trim a cell value from a grid view.
row.Cells[i].Text.Trim().Length
The result return is always 6.
I have checked that the value of this is empty, when I display it on page using this code,
Response.Write(" '" + row.Cells[i].Text.Trim()+ "'<BR>");
I get ' ', it seems like there is a space in it.
I have a standard gridview, populated via a SQLDataSource, with columns converted to templates.
The edit templates have text boxes. When saving edited data via these text boxes, I need to trim the values to remove any spaces.
How do you recommend doing so? I've tried various methods but none seem to work.
Currently my update parameters are specified in the SQLDataSource.
I am using a gridview populated via a SQLDataSource. When editing or inserting data via the gridview, how do I trim the values before they are inserted to or updated in the database? I want to ensure that no spaces are accidentally added to the end of my text values.
View 4 RepliesI 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 have a LinkButton that is databound to a description. Sometimes the descriptions are very long and unorganized so I would like it to show for example 75 characters and then append a '...' to the end of any description greater than 75 characters.
