i have a grid in which i did this :
i get into console it is giving this error on update click :
Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Updating is not supported by data source 'ExistingSqlSource' unless UpdateCommand is specified.
I'm trying to understand how to get the UpdateCommand to work with an Access DataSource and a GridView controlI can click Edit which opens the row for editing, change the Department Field, then click the Update link. The page refreshes, but the change I made is not updated. I have tried hard coding the UniqueID field with a '1' and hardcoding a new Department code into my code and that works. But I really need the interaction with the user version to work. This is my first attempt to use VS 2008 with a web page.

On update the dropdown value shows NULL in database : here's structure for my gridview
<asp:TemplateField HeaderText="Construction Phase" SortExpression="Phase_Name">
<EditItemTemplate>
<asp:DropDownList ID="EditedDropDownInGrid" runat="server" CssClass="form-control" DataSourceID="PhaseSQLDataSource" DataTextField="pp_name" DataValueField="pp_id">
</asp:DropDownList>
</EditItemTemplate>
[Code] ....
It updates other controls in gridview but does not update my selected dropdowns item value in Integer format which is inside gridview...
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.
How specify input parameters to UpdateCommand
View 3 RepliesI'd like to pull several NewValues from a FormView and write them to a database as part of the Update command.For some reason, I am unable to do this using the following code. Is there something I am missing?
[Code]....
Using the code below, I am able to load my dynamic dropdownlist and supply it's selectedindex. But when I fire the update command I can see that the information displayed has been lost.
when I fire the update I don't lose data!

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:
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateEditButton="True"
I have a gridview that I'm trying to update the Date something is corrected in the database. When I am putting a new value in, it is updating, but it isn't updating the new value, just the old one that is already there. I cannot figure out why this is happening.

Here is the situation I have, I have a repeater inside a Usercontrol. The datasource is a IEnumerable<Investor> Exposed through a UserControl's Property. I have overridden the UserControl's databind event to set the Repeater Datasource before databinding the repeater. When it's not a postback, it databinds find and the events on the repeater item's controls fires up fine. But there is one event on repeater items (Delete Investor) which call back the DataBind of the UserControl after removing the Investor from de datasource. When this Event is called, it does all the work (deleting the investor and so on...) calls back the usercontrol's databind but when (within the usercontrol databind) the repeater is databinded again, the repeater items doesn't update (repeater items for investor not on the DataSource anymore still appears). My ItemDataBind doesn't even fire by then.

and code bedind

I Tried with both the Repeater Item Command and each LinkButton Event to see if it would make any difference, but none worked
I have a parent gridview which has a child gridview in the itemsTemplate. Both are binded to different SqlDataSources. I can successfully update and delete rows in the child gridview. After updating in the child gridview, some related data in the parent gridview are not updated automatically. So i have placed ParentGridview.Databind() in the rowupdated event of child gridview. But it doesnt look working.
How can i accomplish this?

I have a GridView with 5 fields. Only two of the fields are edittable (the others are READONLY).
I have an UpdateCommand as follows
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:NHLPOOL %>"
SelectCommand="SELECT [PlayerID], [Firstname], [lastname], [Goals], [Assists], [Goals]+[Assists] as Points, [AsOfDate] FROM [PlayerStats], [Player] where [PlayerStats].[PlayerID] =[Player].[ID] ORDER BY Points DESC"
UpdateCommand="UPDATE PlayerStats SET Goals =@GOALS, Assists =@ASSISTS, AsofDate=GETDATE() WHERE PLAYERID = @PLAYERID">
</asp:SqlDataSource>
The issue is I want the PLAYERID GV column to be READONLY but I get a runtime error when updating if the PLAYERID is READONLY.
I get the error "
Must declare the scalar variable "@PLAYERID"."
I am using LINQ to SQL and on my DetailsView it updates fine but with my gridview it is not. Both I used template fields so I am not sure what the issue is?

I have a gridview and I want to update a cell with a session variable username. In the Gridview1_RowEditing event I have this code :
GridView1.Rows(e.NewEditIndex).Cells(5).Text = Session("username")

I am trying to update gridview record, i am not getting any error but its not updating the record either.

Having a bit of difficulty working this gridview update problem out - I have managed to get edit/update function working but instead of only updating the current gridview row it is updating the whole table I believe this is due to a missing where statement on my Update statement - to single out the row index of my grid row.When I configure my sql datasource I am using custom statements Here is my update statement
UPDATE SimpData SET store_nbr = @store_nbr, date = @date, data_type = @data_type, acct_1 = @acct_1, amt_1 = @amt_1, acct_2 = @acct_2, amt_2 = @amt_2, acct_3 = @acct_3, amt_3 = @amt_3, cheque_nbr = @cheque_nbr, cheque_amt = @cheque_amt, gst_hst = @gst_hst, qst = @qst, comments = @comments, uploaded = @uploaded

i have a DropDownlist in my GridView that is bind to another DataSource than the GridView.
For the display it is working well but when I want to update datas I m stuck. Something is wrong and I don't know why.
[Code]....
I am stocking in the Database the value of the dsDroit but when I want to update the field I just know how to get the text not the value.
I have a gridview that holds 4 columns. in the fourth column there is a DropDownlist that holds three items.
I want my users to select one of the values and when they do the auto post back (which is set to true) should execute a method that updates the database selected row. But do i use the selectedindexchanged of the DDL or the Gridview? My head is totally thrashed so i imagine its really simple and im just over thinking it.
[Code]....
i wanted to refresh the gridview once user enters values and clicks update button. But its not updating. If i change my selection to pop up gridview, then it is showing the updated values. I dont know where i am doing wrong. can any one suggest changes in my code?
[Code]....
I'm using a GridView to retrieve data from a stored procedure using a SQLDataSource (db is SQL Server 2008). When I compile my application and go to my website, all the data is loaded and shown fine. If I was to add a new entry to the table however (a seperate page on my website has a Wizard control to facilitate this) and then return to the page with the GridView, the new entry doesn't show up.
Looking from SQL Server, the data has been added, but the GridView isn't updating to show it. If I were to recompile the project with F6 and refresh the page, the new data will show up. I tried calling DataBind() on the GridView in the Page Load event, however the issue still remains.
