Forms Data Controls :: Cannot Reference Text Value In Footer Of Gridview Control
Sep 19, 2010
I am trying to implement adding a new record using the Gridview footer.
I have an example that works finethat I got from [URL]
My situation is a little different .. as I am using master page and the Gridview is in a page derived from the master page.
I have tried:
Dim txtNewName As TextBox = DirectCast(GridView1.FooterRow.FindControl("NewName"), TextBox)
"NewName" is the ID of the textbox in the footer of the Gridview.
When I try referencing ... txtNewName.Text ... it returns a null value.
There must be some trick to referencing this .Text value when using the Gridview that is within a Content Place Holder that results when using a page that was created using a master page.

After displaying a summary data in Gridview Column Footer in ASP.Net...is there a way that i can then use that summary(total information) in other parts of the application? For instance, like adding the total from the GridView footer to a different data that appears in a textbox somewhere else within the app?
So if i have a GridView like this
entry1 10
entry2 20
Total 30 <----this is the info in the footer
then add this footer total to a total from another control? How can i get this done? How do i go about using that total from the gridview in my app?

I display the incrementing number in the header. I create a column to show the current Row Number, but I'm not sure how to display the header text (Incrementing number) in the corresponding footer. Is there a special trick for it if I'm creating columns on the fly?

I've been trying to get the total of some columns in my GridView. I used the code in the MSDN and finally did this:
[Code]....
GVcm is the name of my gridview.I have a button that loads the gridview, but it does not show the total. I don't know if I have to call this method inside the ButtonClick Event, I'm still a noob with c# and asp.net.Other things that maybe you should know, I'm not using template fields, I don't know if that is the problem I'm using normal bounfields.

If I want to add the value of a GridView footer to say, the values in 3 textbox, and then put the summed up value in a 4th textbox called txtSum...how do i go about getting this done? Are there any examples out there that I can take a look at?
So to further elaborate on the task I need to complete...the textboxes do not reside within the GridView. I want to take the total within the footer of the GridView and add it to values that are within textboxes which are located in other locations of the page, then displaying the result in another textBox that is also located somewhere else on the page. Meaning, there are 5 different controls located at several locations on the page which are involved.
(value in footer + TextBox1 + TextBox2 + TextBox3 = TextBox4)

How can i add a textBox to the footer of a gridview? I just want to add one testBox which would display the total of one of the gridview columns. Are there any examples out there that I can take a look at? My google search did not return any.
Here is what my Gridview looks like right now...
[Code]....
Basically i want my grid view to look like this:
First Entry 20
Second Entry 50
Fifth Entry 30
Total (Footer) 100 <== this in a textbox.
So only one Textbox is required in the whole GridView..

I am having problems with displaying the totals in the footer of a gridview. I am writing a page whereby users can enter comments and marks for an online photo competition.
The page has a details view to enter the comment and mark. Its has a details view where the photo is displayed. It has a gridview where the comments and marks that have been entered are displayed.
It works well - the details view allows comment and mark entry and the gridview show the comments and marks as they are entered. The problems are twofold. Firstly the total shows double the marks that should be displayed. Secondly, when you leave the page and then return later, you have to refresh the page before it will show the latest comment and mark even though it shows this immediately after entering the data.
Ive provided my code below:

I wanted to create CrossTab o/p as In Ms Access. tried couple of articles based upon coding in C# but in one way or other they could not give me final result. Then I posted here.
muhammedsalimp almost resolved my query. But only problem I am left with is adding a TotalSum to the selective columns in GridView or In SQL.
It can be seen from the screen-shot that columns 1-7 does not require sum but columns after 7 all will require sum as they are the Items passed their now will vary from day to day.

I have a GridView with column headers that include text and images. I would like to have the header essentially duplicated at the bottom of the GridView. how to accomplish this? I have found some internet resources that have explained how to use the GridView PreRender event to add an extra footer row but I'm trying to find a simple way to populate that row with the same text and images that appear in the header row. I am not using header templates. I am using the footer row of the GridView as the "insert" row.
