I have a gridview and it has two EditItemTemplates. I want to update the items inside the second dropdown (EditItemTemplate) when I select an item from the first dropdownlistbox (EditItemTemplate). I want to update dropdownlist2 when I select an item from dropdownlist1. How can I do this?
I'm attempting to load DropDownLists from the C# codebehind as the FormView switches modes to Edit and displays the EditItemTemplate. I present the data in a FormView ItemTemplate using text boxes. When the user selects Edit, I have been attempting to load the EditItemTemplate dropdownlists by creating a dataset and binding it to the control, without success.
I've successfully loaded them in previous projects from within the .aspx code using <asp:ListItem> and within the C# code behind using Control.Items.Add(new ListItem), which are essentially the same thing of course . This project is different in that I want to get the data from a stored procedure on a MSSQL server.
In my latest attempt, I can see the data in the datasets. I'm getting "Error connecting to database.'eitRace' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value"
I include the code below. If someone could point me to an example I would be greatful. There has to be an elegant way of accomplishing this.
i saw this post on[URL] so the problem is .... if there is a datasource in some editeitem template in grid view .... it won't be accessible from out of the edit-item field.....
here's my code...
that i have here is ID-column which contains a linqdatasource taking a where parameter from a dropdownlist and they are both in the same edit-template field.
and i have in another column (CourseTypeID-column ... edit-item template) a dropdownlist ..... now this dropdownlist i want to bind it to the linqdatasource exists in the ID-column (edit-item template)..... is that possible in the designer (or from) not code behind ..... and how ????
I have a detailsview with three textboxes as itemtemplates. Each for holding a different date. To avoid the option of users entering invalid values the textboxes are disabled and the user can use a calender control to fill the dates. Because the textboxes are disabled I added a linkbutton to empty a date, if the user decides to clear it.
[Code].... In the code behind is the following for linkbutton on click:
Now, the problem is that no matter which linkbutton a user clicks all three textboxes are cleared/emptied. Why?
I would like to move all of this to codebehind so it's easier to work with programmatically. For instance the PracticeId is a selection from a dropdownlist that is populated from another table... i need to determine what the current selection is first so i can display the record / bind properly.
CS0030: Cannot convert type 'string' to 'bool' However, if I use it one a Label it works fine: <asp:Label ID="lblIsPaid" runat="server" Text='<%# Convert.ToBoolean(Eval("is_paid")) ? "True" : "False" %>'></asp:Label>
So another trial I did was to CAST the data from the database to be the text that I want, like so:
SELECT not_paid = CASE WHEN is_paid = 0 THEN 'True' WHEN is_paid = 1 THEN 'False' END ....
System.InvalidCastException was unhandled by user code Message=Specified cast is not valid.

So I wonder, is it possible to change the "Enabled" property based on by boolean value?
I am trying to target a control in a Detailsview in my codebehind, however I am getting an error "Name "control" is not declared" for example, i have a FileUpload field in the edit template of the detailsview, which I am trying to access as
I also tried adding a reference to the Detailsview id such as DetailsView1.FileField.PostedFile.SaveAs("directory")
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.
I've been trying to accomplish this for days without joy. I need to update a specific cell in a gridview with some static text when a button click that is outside the gridview. The cell i need to update is a template field.
I have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?
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?
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.
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.
I have a asp:DetailsView control with the first column are the field headers and the second column is the record details for a given user.
The DetailsView is bound from 4 tables, I need to be able to edit/amend any field. Is there another way I can achieve this from the DetailsView? Would I need to create templates for each table entry then Update SET on each template, would that do it?
I want to update a record in a detailsview which contains a decimal value which I would like the field to formatted as currency while editing.
When I try to update the record I get an error about trying to pass a formatted value to an unformatted table column. The ApplyFormatInEditMode is set to true and you are cautioned by intellisense about unformatting befor updating the record. This is databound field.
Is this a simple as x = Val(detailsviewrow(1).tostring) ?
I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.
I have a bound field in a DetailsView that I want updated with the contents of TextBox2.Text when I update. I have TextBox2 set AutoPostBack True. Cannot remember how to move the contents on update. I tried converting the "Description_Update" to a template field without success.
I can copy and paste the contents of TextBox2 into the DetailsView and it does update as do the other DataFields.
I am using a gridview to select a record and control that record using a details view. I am using a class based objectdatasource to link the data for select, update and delete. Sofar the select works but the update fails. Here is my error message:
ObjectDataSource 'odsDetailsView_1' could not find a non-generic method 'UpdateSet' that has parameters: setId, TYPE, iHPlayer, iAPlayer, iHRuns, iARuns, iH8Break, iA8Break, iHe8s8, iAe8s8, iH15BRn, iA15BRn, iHWins, iAWins, SET_ID, MATCH_FK, HOME_MEMBER_ID_FK, AWAY_MEMBER_ID_FK, HOME_TABLERUN, AWAY_TABLERUN, HOME_8BALLBREAK, AWAY_8BALLBREAK, HOME_E8S8, AWAY_E8S8, HOME_15BRN, AWAY_15BRN, HOME_TOTALWON, AWAY_TOTALWON, HOME_POINTS, AWAY_POINTS, LOCKED, GROUP_FK.
The first group of parameters have lower case letters and they come from my objectdatasources update method parameters. The second group of parameters are all capitalized and they are the fields in my SQL database table (and I don't know how they wound up in the error). This might be a clue.When executing the code my class method never gets the chance to execute because the error pops up before the code gets there.
I'm trying to use the DetailsView to make Updates. The problem is that it can't handle empty fields even though the underlying table field allows nulls.
I get a message like this if I change the "State" field to blank when doing an update
The parameterized query '(@Cust_ID int,@Cust_DL nvarchar(7),@DL_State nvarchar(2),@Last_N' expects the parameter '@State', which was not supplied.I'm using an object data source control which is calling the EditCustomer method in my Customer Class. I'm not sure how to fix this.
