Forms Data Controls :: GridView To Excel Data Duplication - How To Stop It

Jan 15, 2010

I am new to ASP.NET but have had about a year of experience with VB.Net. Currently I am working on a webpage where I can download my inventory list from a GridView control to an excel spreadsheet. The routine is very straight forward however I cannot get it to stop duplication data in the spreadsheet. When I run my routine it inserts the gridview twice in the spreadsheet, the second one immediately to the right of the first table...

[code]....

It renders perfectly on the page by using the following commands:

I have tried a little bit of everything to stop the duplication and am completely stumped.

Forms Data Controls :: Make The TextBox In The Gridview Template A Datasource?

Feb 6, 2010

I have a datagrid, with a template with a textbox in it. I am trying to add a "update" feature to my datagrid, writing my own code. Stuck on one thing though. I try to update the DataSet with this code:

[Code]....

But when running the code, an error message is showed saying that there where no changes to the GridView. This should probably be because the textbox in the gridview is never declared as a datasource for the gridview. How do i make the TextBox in the gridview template a datasource?

Forms Data Controls :: Multiline Textbox In Gridview - How To Make # Of Rows Depend On Content

Jan 26, 2010

Language: C#

Values for multiline textbox in gridview are coming from SQL db "text" type previously entered by user...sometimes a small amount, sometimes a lot. Want to display enough to make it readable without wasting space on the screen. Can't believe this mechanism is not built in but have researched & see I may have to count lines then set the "number of row" property.

Question 1: Should this be done in databound or rowdatabound event?

Question 2: Could someone provide the "row counting" code (in C#)?

Forms Data Controls :: Accessing Textbox Inside ItemTemplate Of Gridview?

May 17, 2010

I've been searching all day for a solution to this, but nothing has worked.

Here's my scenario: I'm binding the gridview to a datatable. One of the columns is a textbox that will accept user input.

When a "submit" button is clicked, I need to loop through all the rows, get the textbox's text, and add them all together. Simple, right?

I've tried the following (this is on the "submit" button's click event):

[Code]....

The itemtemplate looks like this:

[Code]....

The txtDays.Text property is ALWAYS empty. UNLESS I assign it a value w/in the control. But then it's ALWAYS that value. I need to get the value of what the user enters.

PageView Duplication Inside A Multipage

Jan 23, 2012

I have a web page containing a multipage and 3 pageviews filled with controls... linked to VB server side code.All I want to do, and I imagine it's pretty simple intuitively, is to grab all the controls from one of the 3 pageviews and add it to the multipage.

Now I have 4 pageviews. The 4th one being a copy of either pageview 1, 2 or 3.I looked everywhere and I understand I need to deep copy the PageView and stick it to the Multipage, as I already do for a blank PageView, but I am missing the rest.

Data Controls :: Assign Value To Label Inside TemplateField Of GridView From TextBox?

Jan 5, 2013

In my gridview, I have 6 columns. The first 5 columns are filled with data retrieved from database.In the 6th column I want to display a value from textbox from same form. The value should be displayed on the row next to last row of rest of the columns. So my last column (i.e.) 6th column will just have all the rows filled with the same value of the text box.

First 5 columns of grid will be filled by selecting the college name from dropdown.The last colum (Date) must be filled with the date that is given in the textbox.It can be even after button click event(date of attendence).

It can be done after button click event also..
