Forms Data Controls :: How To Trim Values Edited Via A Gridview

Jun 1, 2010

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.

Forms Data Controls :: Extracting Edited Values From GridView, To Update/insert To Database?

Jul 28, 2010

I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.

I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set
to an instance of an object" error when I click the Update link for the row of data being edited.

At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).

For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).

Forms Data Controls :: Cannot Trim A Cell Value In Gridview

Jun 22, 2010

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.

Data Controls :: Add Dynamic Rows In GridView With TextBox And Keep Edited GridView Row Data On Post Back

May 7, 2015

I have 3 textboxes , 1 dropdown , 1 Button and 1 gridview .

Textboxes ID are :ACode , ADesc , ASeq
DropDown ID is :CPhase
Button ID is :AddRowBTN
GridView ID is :PhasesTempGrid

Now whats the story is ?After adding some data into textboxes , when a user clicks ADDRow BTN , that data gets saved into datatable , then that datatable gets binded to gridview and it shows my textboxes data in it .

What i want to achieve ?In my gridview i am use templateField and inside that template field there are textboxes ( Let the users edit the row without clicking any button ) .

Take an example of dummy data and problem persisting in there :for e.g i put some data in textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"Then i click Add BTN , it saves the data in datatable and show in gridview , now if i do this in gridview :ACode = "Edited ABCD"ADesc = "Edited EFGH too"ASeq = "WoW There"Then i click Add BTN , it removes the edited record in gridview and shows original data which had came earlier from textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"I don't want that to be done ... Simple is that user can enter data from textboxes , click the btn to submit into grid then he can edit the data like he want ... data must not get flashed , here's my coding i have done so far : 

public void AddNewData()
{
var dt = new DataTable();
if (ViewState["myDatatable"] != null)
{
dt = (DataTable) ViewState["myDatatable"];
}

[CODE]...

here i havent added dropdown combo in gridview but you can do it so that it will save my time (Bind it just the way PhaseDropDown have bind)...

Trim Values In Detailsview When Databinding?

Jul 7, 2010

Is there an easy way to trim values in a details view during edit mode? I tried modifying the database query to trim the values, but it didn't like to do both ways databinding after that. I tried looking through all the properties of the text boxes themselves and found nothing. I know I could add an event handler for the databound event, and set all of the values one by one, but this is an application that has existed since before my employment and there are over 40 values in this details view, all in text boxes with seemingly random names that have little to do with the values they represent or obvious naming scheme.

I thought maybe there was a way to way to iterate over the DetailsView.Fields property, but couldn't figure anything out there either. I am not allowed to change the schema from CHAR to VARCHAR either. Any other quick ideas? There is a strong likelihood this page will change again, and I would like something that might take care of this problem for any new fields added in the future without extra work. Unfortunately, redesigning it is not anywhere near a top priority right now, so a quick fix to alleviate some of the headache of using this monstrosity is all I am looking for.

Forms Data Controls :: Export Multiple, Edited Gridviews To Excel

I have 3 gridviews on my page, all with the same columns. I want the user to be able to click on a button and it export all three gridviews to an Excel file, whether on 3 different worksheets or the same worksheet (preferrably the same, but either will do).

And in code behind, I insert footer rows to total by department, so if I use this

Export to Excel control it will export only 1 gridview at a time and won't export the inserted footer rows separating the departments.
