Forms Data Controls :: Loop Gridview To Update Values In Gridview To Stored Procedure?
Jan 14, 2010I would like to ask a question on the visual basic codes to loop the gridview to retrieve the values and based on the values, it will be provided as parameters to update to the database table using stored procedure.
Firstly, I have a gridview named grvProduct. The page (ui) will be loaded with data from the database with the use of stored procedures. And only certain values can be edited through the use of template in gridview. So based on those edited values, I'm supposed to pass these values as parameters to the stored procedure which will then update a database table.
Let say, I have 3 records retrieved from the database and displayed in the gridview. And I would like to edit a values in the 3 records, how do I do batch update and pass those parameters to the stored procedure? I went to debug and step through the visual basic codes and realised there were too many arguments specified because I actually loop the gridview.
Below is my visual basic codes:
[Code]....
Below is my Stored Procedure code:
[Code]....
I believe it is the error in the looping of the gridview which results that I could not batch update the data/values.

Forms Data Controls :: Loop Through Bulk Gridview?
Dec 15, 2010I have a Bulk Gridview(all rows are editable) I need to loop through.I need to get the text that's displayed in each of the textboxes in the gridview, my current code is this:
[Code]....
like this, I need to loop through the gridview, but instead of just getting the text in each column, I need to get the text from the textboxes. How can I do that?If i'm going to use findcontrol() then I need the ID of each control. the gridview is always created dynamically, which means I don't know the number of controls that's being created beforehand. So, how/where can I find the ID?Is there another way to extract data from the textbox, other than findcontrol()?
Forms Data Controls :: Multi - Edit Gridview Without Row By Row Loop?
Mar 3, 2011I have found demos of multi-edit gridview which basically mark each row as edited then loop through them:

Forms Data Controls :: Loop Gridview Rows To Read One By One
Mar 24, 2011How do I loop the gridview to read or insert one row by one row?I have a database which has a Primary key.

View 6 RepliesForms Data Controls :: Loop With GridView To Detect Updates/changes?
Nov 9, 2010I have a two gridviews that I populate it through some tables from a database.
In the same page I have a ASP:Button with onclick event.
When click is perform I wish to write a code that compares the old values of both gridviews (that retrieved from database), with the new values, and if changes were made then create the changes in the database.
I think that the best way is to loop every gridview sepertly, and compares it with the values in the database
How do I do that? Do you have a sample code that loops on gridview and compares with the old values to detect changes?

Data Controls :: Loop Through Parent And Child / GridView And Same Data To Database
Mar 3, 2014 I have nested gridviews, in the outer grid I am displaying the question and in the inner grid 4 options are displayed in radiobuttons. I have kept Lock Answer button inside Item Template in inner gridview , so this button is coming with each and every question and when i click on Lock Answer button in front of any question, its saving the corresponding answer in the database. For ex, if there are 10 questions this button is coming with all the questions, all the questions are on single page and all are multiple choice. Now everything is working mine, my requirement is that I need on 1 common Lock Answer button at the bottom of the page and not with all the questions. And when I click on that common button it should run for all the questions that are displayed on the screen at should fetch and update each unique answer corresponding to that question in the database. Below is my code:
<asp:GridView ID="gvouter" runat="server" GridLines="None" AutoGenerateColumns="False"

Forms Data Controls :: Loop Through Different Sets Of Rows In A Datatable?
Oct 13, 2010I have a following scenario - A use selects criterias from a webform (C#) - a result is then returned from the sql. Say, to start, there are 2000 data returned from the sql and are stored in a dataset.
Now, the user wants to choose a number of drops (up to 6) - with the number of drops selected, they can enter their own quantity in each box. So, they can divide the 2000 records into 6 different drops. With each drop, there is campaigncode created based on the mail date and the job number they provide.
So, now i have the 2000 records in a dataset. What i want to do is loop through the gridview where the user fill out the quantity depending on the number of drops (for ex: if they say 3 drops, then there will be 3 rows in gridview with 3 quantity box to fill).
In the loop, I am getting the quantity, dropdate and the job number. The Campaigncode is created as well. Then, i am looping through the datarow in the dataset; updating the Campaign Code column with the CampaignCode for the number of records thats set in a loop. It works but the Campaign Code is not populated for the next set of records.
Here is the code:
[Code]....
I think its this line right here thats causing the problem. But i don't know how to tweak this so as to accomplish what i want to do.
if (Convert.IsDBNull(DSAEFile.Tables[0].Rows[i]["Campaign Code"]))
