AJAX :: Unable To Update DetailsView?
Apr 8, 2010
I've been following the tutorial from (hxxp://mattberseth.com/blog/2008/04/masterdetail_with_the_gridview.html), and trying to implement it in my web app.
I get details view showing up with right data and in edit mode, but when I try to update I get following error:
Error: Sys.WebForms.PageRequestManagerServerErrorException: Could not find a row that matches the given keys in the original values stored in ViewState. Ensure that the 'keys' dictionary contains unique key values that correspond to a row returned from the previous Select operation'Source File: http://localhost:60402/ScriptResource.axd?

I have two sets of cascading drop down lists they are contained in a detailsview <edititemtemplate>. The problem is that when the user clicks update; the original data is wiped out and the user has to redo the selection of all items contained in a cascading dropdown even if the user didn't want to change that particular aspect of a record. If the user doesn't select everything an error is thrown by the stored procedure in regrds to null values not being valid.
Is there a way i can use cascadingdropdown so that the current values are visible when the user clicks update; meaning that they don't have to redo selections for all items involving drop down lists. The current selections would be default values.

i have a religion dropdown1 , on this selectedindexchange i have to populate castes into the listbox(not dropdownlist).
i am unable to use cascadingdropdown as it is tightly binded with dropdowns.
please guide me how do i update listbox items based on the dropdown selected value using ajax.
i tried with pagemethods getting the dictionary object using JS function and thought of binding it.
but i am unable to bind the list.
//html code
Religion
<asp:DropDownList ID="ddlReligion_RS" runat="server" TabIndex="6" onchange="GetCastes_RS(this.value);">
</asp:DropDownList>
<br />
Caste
<asp:ListBox SelectionMode="Multiple" ID="lstBxCst_RS" runat="server">
</asp:ListBox>
//js function
function GetCastes_RS(relgnID)
{
abc.BLL.Services.AjaxService.GetCastes(relgnID,
function (resp)
{
var ddlCaste= document.getElementById("<%=lstBxCaste_RS.ClientID%>");
ddlCaste.length=0;
var castesList = resp;
alert (resp);
if(castesList.keys.length >0)
{
for(var i=0 ;i< castesList.keys.length;i++)
{
op=castesList.keys[i];
ddlCaste.options[ddlCaste.length]=new Option(castesList.values[i],op);
}
}
},
function(val)
{
alert(val.get_message());
}
);
}
i could call the webmethod, but i am getting this error in javascript.

when gone thru few links i have seen few examples supporting dictionary object , why not in my case?

My problem is that I have tried to update my gridview which is inside my updatepanel but the data in the gridview does not update or change when I change the data in my database.
I have used the basic method of using timer to change the label like this Label1.Text = DateTime and with trigger <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />. Timer is <asp:Timer ID="Timer1" runat="server" Interval="1000" Enabled="true" OnTick="Timer1_Tick"> .

I have a page that binds data from DB to a DetailsView.I want to use the auto-generated Update command.
Everything went OK, and also updating was successful, but if I remove any field that I don't want to have chance to update, then the Update command doesn't update! the old values retain!
I mean: if all of the fields are present in the detailsView, the update will be OK, otherwise, the update will NOT update any thing.I've tried to mark the fields that I don't want to view as "Visible = 'false'" but with no good results!

I have an update button in a detailsview. based on certain criteria in the data that is being updated (blank field), I want to stop the update from happening. I tried putting the following code in my UpdateButton: 'check to see if the status is 'complete'
Dim statuscheckbox
As CheckBox =
TryCast(formulationDetailsView.FindControl("FormulationCompleteCheckBox"),
CheckBox)If statuscheckbox.Checked
Then
'check to see if color code has been entered
Dim colorcodetextbox
As TextBox =
TryCast(formulationDetailsView.FindControl("ColorCdTextBox"),
TextBox)If colorcodetextbox.Text =
""
Then
'show a message, the color code has not been entered
MessageBox2.Text = "Please enter Color Code prior to complete"
statuscheckbox.Checked = False
resetformwithoutediting()
End
how to stop this code from proceeding to the update?

Not sure where I went wrong with this one, but I can't figure it out now... I've got a DetailsView in an UpdatePanel. A dropdownlist controls which person's details are displayed in the DetailsView. I have the DataSource set to an ObjectDataSource, which has select, insert and update methods defined. I also have a method for the ItemCommand, ItemInserting, ItemUpdating and DataBound events of the DetailsView specified.
When I click "New" or "Edit" on the DetailsView I get the open form with either the details for the current person, or a blank form, exactly as I would expect. But when I click the "Update" or "Insert" buttons it does absolutely nothing. I have it running in debug, and have put breakpoints in the ItemCommand, ItemInserting and ItemUpdating methods, right at the top, and it never goes there. The form remains open, and nothing happens. If I click "Cancel", it posts back and goes back to ReadOnly mode.
A couple more minor details that may be important: This page is using a Master page, which is where the ScriptManager is. I'm actually using the ScriptManager from the AjaxControlToolkit. I also have a GridView in this same UpdatePanel, and that has a FileUpload control in it. Because the FileUpload control doesn't work properly without some tweaking, I have to call a RegsiterPostbackTrigger method on page load to link it back to the Master page's scriptmanager. Not sure if that's causing any issues...?
I had this working fine, but then as the page got more complex and I had to change some of the code, at some point it just stopped working and now I can't figure out how to get this working again... I'm happy to post code if necessary, just thought I'd try this first to see if anyone has a quick idea for what to check.

I've got a DetailsView control with Edit and Update enabled. I'd like to write the edited record to an XML file after Editing. What's the best way to do this? I thought I could write to a text file and concatenate the db fields between XML tags but is there an "automatic" or best practice way to do it?
