Forms Data Controls :: Loop Through Bulk Gridview?
Dec 15, 2010
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 a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.
I have a gridview with checkboxlist for each record. I was updating each record individually based on that check, but now they want it to be a bulk update instead of individual. So i have commented out my individual update and added a button below the gridview and created my button event, how to loop thru the gridview and find the checked records and call my update procedure.
i found something kinda close to what i need, but its in VB and not sure how to convert that to C#
How to do bulk edit/update with checkboxes in GridView control where in the selection of editting a row needs to have some info brought from db for validation on update?
I'm having a gridview in my aspx page with checkbox, User can select one or more than one record(s) at a time and clicks on delete button, Then i'm constructing an object of my DTO and adding all the checked row's Primary Key (DataKeyNames - GUID's in my case) to a serializable class and generating an XML and sending it as parameter to the Stored Procedure.
My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??
If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..
My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List?
Which one is better, I mean ObjectDataSource or SQLDataSource or my XML method?
I 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?
Is it possible to loop through a gridview and based on if a checkbox is checked, then change the backcolor to that current row? I have gave a few attempts, but luck.
i have a form in which when i enter value and upon pressing submit button all the data were shown
on the grid.from where i can edit and update the grid view. in this case i can edit the only particular row. but i want to edit the whole grid and then update it. means bulk edit
Share the code regarding bulk edit and update according to my above mentioned code.
I am following this article in aspsnippets. I followed each and every line, but when the user check the check box, the row become highlighted and it turns light yellow. I could not figure out where the code to make the row yellow/highlighted is and the gridview in my code is not turning yellow either. URL...
I need to make sure only one checkbox gets checked in a GridView. I have tried a solution on here, but I get an error. The other is looping through the checkboxes in the gridview to get the value, in this case, a date.
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 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 want to add each value of 'k' to a gridview..If I have 10 values for 'k' (count=10), then I want to display a gridview with 10 rows...How can I do this?..
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:
[Code]....
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 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 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'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:
This is my for loop code, it is working fine , just the problem is, if there are 10 rows , it runs for 9 rows and not for 10th time? What correction is needed?
protected void gvouter_RowDataBound1(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { int count_rows_for_saving_answers = gvouter.Rows.Count; for (int ii = 0; ii <= count_rows_for_saving_answers - 1; ii++) { Label lblsubid = (Label)gvouter.Rows[ii].FindControl("lblsubid");
