Forms Data Controls :: Using A Gridview To Perform Bulk Update?
Feb 9, 2010
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#
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.
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?
if it's possible to use the Gridview (SQLDatasource) UpdateCommand to actually perform an INSERT and not a true update.Here's the dealUsing a Select statement in my SQLDatasource,I'm retrieving records for which there are no History records for a specified period.(Essentially, I'm asking "Show me all records for which there are no historical records within a specified range").I'm using that result set to feed my GridView. Basically, I'm displaying all I need to know about the insert records sans one piece of info.When the user choose the "Edit" button, the row goes into edit mode.Using a template field, I've created a drop down box to allow the user to input the status of the data for that particular time period.When they click the save button,the idea is that the UpdateCommand will fire.However, when I click the save button (in edit mode),I get a postback error that tells me System.Data.SqlClient.SqlException: Must declare the scalar variable "@EQP_PK".
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 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 an ASP.NET GridView which displays a list of neighborhoods.
I wish a user (administrator) to be able to edit the neighborhood name.
Now, the database is quite complex, and as such, i can't simply provide an UpdateCommand / SqlDataSource for the GridView.
I bind the data manually (on first load, and on the PageIndexChanging event).
Binding/listing paged data is working fine.
However, i'm having trouble trying to UPDATE the data.
The user clicks the "Edit" button, the textbox for the neighborhood name is shown, i change the text, click "Update", but the RowUpdating event is not firing.
I basically want to grab the row that was edited, and perform a custom update using LINQ.
Is this not possible with a GridView? If it's not, what are my alternatives? A repeater with LinkButtons and a hidden textbox that can swap in/out the labels?
I have the following gridvew that contains this information below
Type_id quantity Red 2 Blue 3 Green 6
Now, I would like to add a small button next to the type_id, so that whenever the user clicks on it, it reduces the quantity by 1 through the use of query, I wrote. see description below
Type_id quantity (button) Red 2 (button) Blue 3 (button) Green 6
I have placed Chekc box in Gridview when i select the check box can perform 2 operations simultaniously one is entire recordset is populated into form fileds and second one is can delete the selected record permanently from database table.following code for this fuctionality.
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 select few columns from table A in dataset. Example "EMP_ID","Name","Address","Phone_Number". I want to save data in this dataset into some other table B.
I want to save data from dataset into table B. But i want to have following functionality
1. Before saving a record from dataset to table B if that record if previously present in table B, if yes then check if any value are different, if yes then update that record with the record from dataset, if all the values are same then leave the records as is.
2. If the record is not present in table B then insert it new records in table B from dataset.
Is there any efficient way to implement in .NET C#.
