DataSource Controls :: Sending Checked Gridview Row To Database
May 10, 2010
I'm working on a web application in Visual Studio 2008. I'm using gridview to pull data from our database (I'm using a SQL Datasource) . I have a template field with a checkbox function and it allows you to check certain rows and disable them. What I am trying to do is send the enabled rows aka the non selected rows to a seperate table in our database. I'm assuming its just some kind of insert statement but I'm stuck on specifics..I am getting a object reference not sent to an instance of an object error. The line that is higlighted is, cmd.Paramters.AddWithValue("[Wrk_Pgrm_ID]" txt1.Text);
Below is the code i recieved from an earlier thread that I have modified.
Now I am passing selectedUserTypeIDs along with other details to my Stored Procedure and adding those UserTypes for newly Added menu. It works fine for me. Now I want to show checked CheckBox in Edit Mode.
i have code to update multiple rows in a gridview. What I want is that if the row value is = 1 in the database then the row is checked otherwise it's not. I've put some pseudo code in below to illustrate what I want to achieve.
I have a gridview inside which there are 4-5 checkboxes. In that gridview, I have 10 rows too. So, Now what i want is.
IF I check, 2 checkboxes and don't check remaining checkboxes. how to save the value of the checked checkboxes value as Y and unchecked checkboxes value as N into the database.
I have a gridview and users would select some records and would click on the submit button and i will be saving those records into database using a stored proc.... now .... just below the gridview and above the submit button there are few checkboxes by default they wud be checked. How would i save the selected values and the checked boxes in database i wrote the stored proc for the gridview but how would i save the checked checkboxes into the same table.
For i As Integer = 0 To gvSelectScreen.Rows.Count - 1 Dim chkTemp As CheckBox = TryCast(gvSelectScreen.Rows(i).FindControl("cbStatus"), CheckBox) If chkTemp.Checked Then ContractNumber = gvSelectScreen.Rows(i).Cells(0).Text ClientProgramNumber = gvSelectScreen.Rows(i).Cells(1).Text ClientProgramName = gvSelectScreen.Rows(i).Cells(2).Text StartDate = CType(gvSelectScreen.Rows(i).FindControl("txtStartDate"), TextBox).Text EndDate = gvSelectScreen.Rows(i).Cells(5).Text Dim connStr As String = ConfigurationManager.ConnectionStrings("MainConnectionString").ConnectionString Dim myCon As New SqlConnection(connStr) Dim cmd As New SqlCommand("usp_ParametersFromGrid") Dim dt As New DataTable cmd.CommandType = CommandType.StoredProcedure cmd.Parameters.Add("@ContractNumber", SqlDbType.VarChar, 22).Value = ContractNumber.ToString() cmd.Parameters.Add("@ClientProgramNumber", SqlDbType.VarChar, 22).Value = ClientProgramNumber.ToString() cmd.Parameters.Add("@ClientProgramName", SqlDbType.VarChar, 100).Value = ClientProgramName.ToString() cmd.Parameters.Add("@StartDate", SqlDbType.VarChar, 20).Value = StartDate.ToString() cmd.Parameters.Add("@EndDate", SqlDbType.VarChar, 20).Value = EndDate.ToString() cmd.Parameters.Add("@RequestID", SqlDbType.VarChar, 50).Value = RequestID.ToString() cmd.Connection = myCon myCon.Open() cmd.ExecuteNonQuery() myCon.Close() End If
Now above the submit button as i said, there are few checkboxes and they are checked by default...how would i save the selected item (in the gridview and the checked checkbox values in the same row in the database(sql server)
I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
Scenario: I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is: I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
I've created a SQL Server Express database to use with a program I'm working on in Visual Web Developer 2008. The connection works fine according to the Add connection-wizard in VWD. However there's a problem when I try to select data from the database and present the data in a gridview. The error message says that the gridview isn't connected to the database. The gridviews DataSource ID (source-mode) is the same as the name of the database. In design-mode, when I try try configure the datasource I get to a point where I have to configure the select statement, but I just want the connection to work in a way that let's me write the sql-statements in the aspx.cs-file.
I am trying to add the checked rows into the database by looping through but im getting this error:
Object reference not set to an instance of an object.
Description:

i'm new to programming and i'm doing a project of ana e-store, i have a data gridview that brings data from a data base and it have to more templeate files one a textbox and the other one is a label. and i have a button outside the grivdview. what i need that when i press on this button it will take the values from the grid view and insert them into a new sql table.
[Code]....
and here is the VB code that i'm trying to use with no luck : [Code]....
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:
As the subject says, i display a gridview filtered from 3 dropdownlist, wich all the items are from a local Data base, once i display this gridview i want to select a row with a button then and add, modify or delete data from it and then this new info is saved on the data base, so when i display the grid again i will see the new info. Im working on visual studio 2010, i dont use code behind, all is in asp .net.
I have a website that displays information from my database into a gridview. The gridview has a checkbox, that once selected, is suppose to move a 'Y' into the field that has the checkbox selected. I have it generating the code, and displaying the code on my page to confirm, but the database is not being updated. Here is my code,
I am transferring selected rows from 1st gridview to 2nd gridview and removing rows from second gridview when I deselect row from 1st gridview using Javascript and it is working fine. But when I am deselecting the same row 2nd time it is not removing from 2nd gridview. html and javascript
<head runat="server"> <title></title> <script type="text/javascript" language="javascript"> function AddRow(lnk) { var rw = lnk.parentNode.parentNode;
I have Gridview on my webapplication and it is getting filled with multiple rows . When clicked on Save I want to Insert all rows without calling multiple database hits.
Is there any way I can insert all rows by single db hit?
I need to store time in database and then show in using gridview.I wonder how to store and show data so that user will see correct datetime depanding on his timezone?
I am confused here as to how to handle this. I have a stroed procedure that using the IN clause like so:
[Code]....
Now, partners can be either a single partner ID like so: 12345 or it can be many like: 12345, 22222, 33333Here is the sqlDataReader from my code:
[Code]....
When partner_list contains only one partner id like "12345" it works fine. If it has more than one then the DataReader states that there are no rows in the reader? I also tried to send the dealer list as a string with ticks, like '12345','22222','33333' but that doesnt work either.

I have a checkbox column in a Gridview that I would like to use to insert the value of one cell in the row into an access database. There will be a maximun of five cells allowed to be selected so there can be one value written to one field in the database up to the maximum of the five fields. The access database has five columns: Selection1 ,Selection2, Selection3 ,Selection4 and Selection5
When the checkbox is checked, the value of one cell (PliD) should be written to each field in the database. Ie: checkbox in row 1 should write PliD value to Selection1, checkbox in row 2 should write PliD value to Selection2, checkbox in row 3 should write PliD value to Selection3 and on depending on which checkbox has been checked. I am not sure how to get the value of the checkbox and write it into the corresponding fields in the database.
