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.
My Master/Detail view is working fine, but if i try to add Modal PopUp extender it does not work at all.
[Code]....
adding Modal Popup to this code. I have studied [URL] article many times but could not find problem with my code. My code should display Modal PopUp 2 times. Once New Client btn is clicked & other time when edit inside GridView is clicked.
i have an issue running JavaScript inside an updatepanel,
i'm using a script as follows:
[Code]....
and each time the update panel updates i load a new variables for the FlashFileName to display a different movie.
outside an update panel this works, but inside the script doesn't run, i have read on other posts that there is an issue with running javascript inside an updatepanel.
Acctually I have done lots of coding on Page_Load of a page which comming from other page. So for that i tried to use ModalPopupExtender. but problem is that its working fine for button but how can i use it for Page_Load.
My scenario is:
protected void Page_Load(object sender, EventArgs e) { PleaseWaitPopup.Show(); //Lots of code and queries;
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 gridview and when i click on the edit button i will get the modalpopup window which is having a popup window i want to update the data in that details view and refresh the data into gridview also.
My file based ASP.Net 3.5 website was working fine. For the pastcouple of days I am getting the following error.Unable to update auto-refresh reference 'ajaxcontroltoolkit.dll" Cannot findassembly c:Program filesMicrosoft ASP.NetAjax LibraryWebformsReleaseAjaxControlToolKit.dll.Project : c:mis.My ASP.Net 3.5 website root folder is c:mis. I browsed to subfolder Bin and looked atBinAjaxControlToolkit.dllAjaxControlToolKit.dll.refresh. The following was the reference...Program FilesMicrosoft ASP.NET Ajax LibraryWebFormsReleaseAjaxControlToolkit.dll
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 GridView control and assosiated DetailView control.
When the record form GridView is seleted, I am showing the details on DetailView.
I have set the Auto generated delete button to true. And now I want to delete the record when someone clicks the Delete button from DetailView control.
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 am trying to update a record using a details view. When the update button is pressed nothing happens, even if I check the db then the record is all the same. No error occurs but there is no update. I am using OLEDB connection with a db2 DB.
How can I programmatically Update Details View. NOT through SQL DataSource or through Wizard. I want to Update the Details View from Code- Behind (.cs)
I have a Drop down list loaded with UserNames, Up on Selecting the UserNAME, I am loading the Details View with User Information.Now I want to Provide Update faeture programmtically.
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?
when I click on "update" button of my detailsview I have the same values on my db table.It seems that the update method don't get my new values inserted in the "boundields" in editing mode.Below there is my code.
