How do I loop the gridview to read or insert one row by one row?I have a database which has a Primary key. Currently,all the rows seems to appear at one time.Even when I use a counter,it did read one row from a textbox(which is for my testing to read one row) but in the database,it still inserts the whole rows from the gridview.I can't click button twice as it will occur an error "Primary Constraint".

I have a gridview in which I add extra rows manually (besides the regular bound rows).The manually added rows do not have a textbox, they are just text.The normal rows hold a textbox "minprice".Now when the user clicks the NewGarage button I want to loop through the gridview and get the values in each row for the minprice textbox.
Gridview structure looks like this:
MANUALLY_ADDED_ROW
NORMALROW <= enter value here works
MANUALLY_ADDED_ROW
NORMALROW[code]...
I have the following fields in an Appointment table:
ID(PK), TeacherID, DayID, TimeslotID, ParentID, StudentID, Remarks & Editable(bit, Default value=1)
I am developing an application to allow parents to book appointments to meet the child's teachers.
It is compulsory for parents to meet child's mentors, hence Appointments to meet class mentors are already pre-booked in the Appointments table.
Parents could still book appointments to meet other subject teachers. I have a column in my gridview to show parents the list of booked appointments. Parents are allowed to change the Appointment timeslot for an appointment they booked and are not allowed to change appointment time for pre-booked appointments.
Under the Remarks colum, it is stated that the following appointment is pre-booked by class mentor.
How do I make only those pre-booked rows read only since all the appointments belonging to a parent is under one GridView.
I found an example, but this is to only make the 1st 3 rows read-only and I don't think this is in VB coding. I'm usingASP.NET VB coding.
I currently have a GridView control on my aspx page with paging enabled and I need to loop through the entire row collection/count to process the selected records. With my current code, it will only loop through the current page of GridView row.
foreach (GridViewRow data in grid.Rows)
{
//here is my code
}
I tried to keep all the data in the gridview when paging, but when I try to save it, which appears in my database only when it is active pages .. ex: in the first and second page I have data in gridview .. when I save, the stored in the database only the first or second page of course .. so I like to keep all my data in gridview when paging..
i have tried using : foreach (GridViewRow row in GridCustomColumn.Rows) but it's not working..
string sql1;
foreach (GridViewRow row in GridCustomColumn.Rows)
{

i have gridview and having few rows. each rows have checkbox,textbox,combo in each column. how can i loop through gridview using jquery and access each elements in rows in loop for collection the value at client side by jquery.
View 3 RepliesI 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"]))

I am taking count the no of rows having AccountLink=2
I need to read all debit,credit and add all debit into totaldebit,all credit into totalcredit independently from table.
then i need to show the totaldiff as Actual.

View 2 RepliesI have a gridview with a template field of check boxes.I have my rows color coded in BLUE color in the gridview based on a database value on page load.Now I want a button on the page to loop through the gridview and select the the checkbox for the rows that are in BLUE Color without a post back.
View 1 RepliesI 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.
How do I loop through a GridView (the actual GridView, not its data source) to check what's displayed in the first cell (a BoundField with int data) of every row?

I 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()?

I have found demos of multi-edit gridview which basically mark each row as edited then loop through them:

I 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?
I have a code like yis
for(int i=0;i<Count;i++)
{

I need to loop through a GridView and get the values of a databound field. Then use those values in my update statement.
Here is the GridView:
[Code]....
And here is my UPDATE statement, which is actually just passing the values to a stored procedure:

Right now, I just have it grabbing the text from a label control, but I know that will not work as it only passes one value. I need to be able to update multiple rows based on the del_doc_num.
I came across a situation where a user selects no of rows from dropdown , depending upon the user input, automatically that no of editable rows should appear to input data...(maximum 8 rows only)
View 1 RepliesI have a GridView, the first column it's a RadioButton template and the second it's a DropDownList Template, the number of rows depends on the user, I mean they are not static. I'm using the following JS function to get the row selected with the radiobuttons:
[Code]....
With this function I know which RadioButton was selected, now, I would like to get the DropDownList value or text of the selected row, I know I have to loop through every DropDownList to get an array of controls, but since they are something like ctl00_ContentPlaceHolder1_GVProducts_ctl02_DValsDropDown, I just don't know how to achive this through JS.
I'm trying to loop through a manually created row's controls in a gridview and set the visible property.
I can use findcontrol and it works fine and I don't have to loop. But there are a lot of controls, so I just wanna do it in a loop. But it never finds the control type I'm looking for. Here's my code:
