Forms Data Controls :: Query About Listbox Control For Updating To Database?
Aug 11, 2010
I do have a listbox control and a button to update values of the list box with few other values of the form to the database. If i select 3 values in the listbox, it has to update the database in 3 rows (Unique for Listbox value) with the other value being the same. I use a details value for inserting values.
I have a web page with a gridview & formview (master/detail relationship) combo. On page load the gridview shows all records from a SQL table. On my page I have a button that when clicked shows the formview in Insert mode to allow users to add a new record to the data. I have also added a column to my gridview that has a link. When a user clicks this link it hides the gridview and shows the formview in edit mode with the detail from the record selected from the gridview.
In my formview I am using a listbox control to allow users to select multiple values. The choices in the listbox are populated by a SQL data table. I have successfully written code to post the selected listbox values to my SQL data field during Insert. When the user selects a record to edit I have code in the databound event to select values in the listbox from the choices based on the value in the sql data field. This works as well. My problem is that I cannot figure out the correct code to update my SqL data when a user is editing the record and makes changes to the selected listbox value. I have included my design code for my listbox in my formview edittemplate and also my behind code that I have attempted.
I have 2 gridviews on a webpage that are fully editable. I also have a button, that when clicked, runs some SQL in codebehind to insert new rows into a data table. The gridview should then update with the latest results of the SQL query, which is does.
Then the user clicks on to the next page to do the next thing.The problem is, when they go back to the first page, they're still seeing the old, non-updated data. I've run the SQL from the page manually on the server, and the new data is there, but the GridView doesn't want to pull it.
I have a dropdown list which provided input to a SQLDataSource query which is bound to a listbox. When the user changes the index of the dropdown box, I want to trigger the SQQLDataSource to requery the database, and repopulate the listbox.
I have set the autopostback = true for the dropdown box. I have also added a Response.Redirect back to the same page in the SelectedIndexChanged method, but the DataSource does not Repopulate. How to trigger the requery?
I am sure I am not the first to ask this question but I cannot find an answer in these or any other forums. I guess I am not wording the question right. In short I have a gridview populated but a database via an SQLDatasource. I have an Edit column in the datagrid and an updatequery in the datasource. When the Edit is click the line goes into edit mode, the user then clicks Update and I get an error. Could not find control 'DropDownList1' in ControlParameter 'Frequency'. The only complication is that there is a drop down control when the "EDIT" column is selected. The dropdownlist gets it list from another SQLDatasource. This all works fine. Here is the code snip:
I have a DataList that on Update calls a function "DataList1_UpdateCommand" to update the data
OnUpdateCommand="DataList1_UpdateCommand"
It does not actually update the new value typed in. I placed a debug on the line below, but the text in the "FieldBalance" displays the original value and not the updated value, but the web pages does display what I typed in and not the original.
Dim FieldBalance As TextBox = CType(e.Item.FindControl("txtBalance"), TextBox) Below is the DataList code and the DataList1_UpdateCommand sub
I have a page where I want to let the users vote on displayed items. My customer wants this done with an image and a VOTE FOR THIS link. The link and image are to disappear once the user has voted, and be replaced with the number of votes for that item. I've made the VOTE FOR THIS link a link button. I'm have two problems:
1) the ListView1_ItemCommand code is always excecuted twice, so the vote count is being incremented by two, not one each time someone votes.
2) A page refresh causes the ListView1_ItemCommand code to run (twice) so a page refresh also casts two votes for the item
If it makes a difference, I display one item per page.
I have a search option which a person can use a multi select listbox. I have it coded so it would loop through to see if its selected or not. I also have a stored procedure where the sql statement is coded for the select statement. For some reason, its not populating my gridview. Where am I doing wrong? Below is the code and stored procedure. [Code]....
I managed to insert items in a listbox (as a cart). The data inserted in something like this 3x T-Shirt @ $40.00 each Black Small 4x Trunks @ $ 12.95 each Blue Large I want to be able to insert this as a chunk of code in 1 column in .mdf
I have listbox which retrieve data from database as follow
[Code]....
if the user want to access editpage , and he made some changes on listbox2 by removeing or adding more rows , it should be edited in database I need the best way to edit it , the way that I am doing now is deleting all record and then entring new record from listbox2 , but sometime it's adding duplicate record.
I have an updatable Gridview control that I cannot seem to URL encode a textbox in one of the columns. I cannot encode some of the other controls in the row, so the solution from the msdn site doesn't work in my case. I only want to encode the single textbox. However, with the code I have, I don't get any errors, and the database is updated, but the column that is edited becomes empty in the database. Here is what I have in the gridview rowupdating:
I've the user creation form where a user will be created by entering username. Below that is checkboxlist for UserGroup which is binded with the dataset with the all the usergroup. Hence up on entering the username and checkbox selected(as the user can belong to multiple UserGroups).At database end, there are basically 3 tables-
So when i click create new user, the UserId along with GroupID(whichever checked) is saved into UserToGroup table.Im relative to this kind of process and hence facing setbacks. Can somebody help in end to end process. From front to DB SP.
I'm just wondering if anyone has come across a good, easy method for updating a SQL Server 2000 DB table using the edit feature in GridView. The catch here is that I need it to encrypt, send to database, then decrypt when the page calls it to be displayed. I have successfully implemented an insert method using FormView with encryption. For some reason, I just can't seem to figure out the edit/update.
A ListBox is being filled from the database, from a SQLDataSource. Im setting the parameters in its _Selecting event. Except when it is done getting its new Data, the ListBox isn't updated with this new data. Eventhough i rebind my ListBox to the DataSource.
when i checked the checkboxes(not all) ,corresponding rows data has to be updating when i click save button which is outside of gridview,Its just same like our gmail delete button.
I've been googling for 2 days for the solution, but I couldn't find something useful. The problem is that I have GridView that is connected to the SQL database and that is how it is being populated. I added EDIT and DELETE buttons in the columns, but as far as I can see the event which handles them is empty.
I have an app where i have a GridView connected to a DropdownList....The selectedIndexChange determines what the gridview shows. Then have coded in the row editing event the ability to change the information in the row. MY ISSUE- cant take the new information changed in the row and update it in the database. I have a row updating event that im trying to figure out how to attach it to my stored proc and the newly edited row

i am making use of two listboxes. the data from one listbox is transfered to other listbox on button click, bt teh the data which is selected must be added to the table in the sql server. but it is not storing values it is throwing execption...Â
private void InsertRecords(StringCollection sc) { SqlConnection conn = new SqlConnection("Data Source=ABCD;Integrated Security=True"); StringBuilder sb = new StringBuilder(string.Empty);
I have created a simple application to edit data in an access database using gridview but its not working , the results are shown correctly , but when i click update nothing happens..
I am using fileuploader control in gridview template control's edittemplate but the problem is when i press edit button fileuploader control and update other controls such as textboxes and press update button there is no value for Fileuploader control so i need the value of image control that is in itemtemplate so i pass it as a parameter.
