I'm dynamically loading a user control with a form view inside, when I'm trying to update the form view the user control disappears on the post back and update never happens;
View 3 RepliesI'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 want to download all the pages from a gridview to excel, I have the code which is working. But the problem is that it gets the data only from the current page.
I tried making paging=false. But it doesnt work. And if i use databind it does not get any data from the gridview.
I'm developing an ASP.NET application with C# and Ajax.I have a page that holds user controls loaded dynamically. I need to pass some data (integer values and some strings) to the user control that has been loaded dynamically.Now I use Session to pass these values, but I think I can use another way; something like VIEWSTATE or hidden input.What do you recommend me?The fact that I load the controls dynamically is important because controls are loaded on every postback, and I can't store any value on controls.
View 9 RepliesI have the follow form view:
<asp:FormView
DefaultMode="Edit"
ID="FormView1"
runat="server"
onitemupdating="FormView1_ItemUpdating">
<EditItemTemplate>
<asp:TextBox
ID="txtPrimerNombreNatural"
runat="server"
SkinID="texto"
MaxLength="30"
Text='<%#Bind("PrimerNombre") %>'></asp:TextBox>
<asp:TextBox
ID="txtSegundoNombreNatural"
runat="server"
SkinID="texto"
MaxLength="30"
Text='<%#Bind("SegundoNombre") %>'></asp:TextBox>
</EditItemTemplate>
</asp:FormView>
<asp:Button
ID="Actualizar"
runat="server"
Text="Button"
CommandName="Update"
/>
This formview is bound in this way:
protected void Page_Load(object sender,
EventArgs e)
{
Persona _persona =
new
Persona();
_persona.ObternerPersonaByUserIdApp(1);
List<SILPA.AccesoDatos.Generico.PersonaIdentity> persona =
new
List<SILPA.AccesoDatos.Generico.PersonaIdentity>();
persona.Add(_persona.Identity);
FormView1.DataSource = persona;
FormView1.DataBind();
}
When the page is shown, the textbox are filled correctly, this textbox are filled with the "primernombre" and "segundonombre" properties from the persona class. After this, If I change the textbox, and after click the update button, I need to update the persona class with the changes from the textboxes, then I call a ActualizarPersona method for updating the database. How can I do for update the persona class when I change the textboxes and click the update button? I try this method protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs
e)
{
}

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.

Have a Formview set up to edit a single record in an SQL table. It displays the record fine, but when you click the "update" link it just appears to do a postback and nothing else.After the postback you're looking at the original record without any of the changes you just tried to make.I went to my Dataset TableAdapter and checked the UDATE query there..it works fine, I was able to change a record.My ObjectDataSource is correctly configured to use the UDATE query--I triple checked all that.

Trying to update a .NET .20 datagridview in the following scenario. A page contains a formview. The formview contains a datagridview and some other fields not in the grid. The formview has its own ObjectDataSource and the datagridview has a separate ObjectDataSource. Each ObjectDataSource has an OnUpdating event. Clicking a Save button triggers the formview update event and the "non-grid" ObjectDataSource updates without a problem. In that same event, I also want to update the grid's ObjectDataSource. Because it's a grid, this OnUpdating event has to loop through each row, get the data for that row and set the UpdateParameter values. A foreach loop can get the values, but how do I trigger the update before looping to the next row?
Should I try calling a different kind of event for the DataGridView's ObjectDataSource? Or is there a way to get all the grid's new data at once as a dataset or datatable and do one bulk update? The datagridview does not have row-level edit/update buttons. It is meant to be an all-or-nothing kind of update.
I have a FormView that that implements all templates (Insert / Edit / Item). When a user updates the form and the operation completes successfully, I want the form to be closed.
I understand that the default behaviour of the FormView is that it returns to ReadOnly mode. I also understand that I can change the default mode so the view will not be ReadOnly, but Insert or Edit. However, I want a much simpler thing - just close the view alltogether (as if it was unbounded).
I tried to change the Visible attribute of the form to False (=Not Visible) at the OnItemUpdated event, but that created consequences errors (something about viewState.... don't want to go there...)
am working with form view for the first time.My issue here is i have an insert item template and edititem template where i have dropdownlist to insert and edit data in to databasemy code below

DataSourceID="ods_ChildPhysicalActivite"
onitemcommand="fv_ChildPhysicalActivites_ItemCommand"

I'm having a problem with a formview i've created. The formview itself uses a costum template to perform updates to the database. Its a form to edit Car details. One of the details is the brand. I use a dropdownlist control to let them select the name of a brand thats in our database, this passes an ID to BLL's update so the car gets updated with a brandID. My update query works perfectly when i try it directly on the database, however, when i use the formview it updates everything except the brand.
When I debug and watch the NewValues object he passes, it does contain the new value for the brandID.
btw, brand is 'merk' in dutch, so brandID is called 'MerkID', and the brandname is called 'Naam'

I have a formview and data source that opens in the edit template and allows the user to update a few free form text fields. I also have some drop down boxes that allow a DOB to be built and populate another text box. All of this was working fine yesterday, and today somehow I hosed it and can not find the cause. I have rebuilt this page three times to get it working again, but I can't figure out what I am doing wrong to break it.

I have a gridview linked to a formview both in an update panel, my triggers are GridView SelectedIndex, and FormView ItemDeleted, ItemUpdated, ItemInserted, and ModeChanged;however, when I insert, or delete in the Formview the Gridview does not update, even though the update panel shows the progress update, and now shows the new record. How do I get the Gridview to update when the panel is updated?

The code which I used is :

But I am getting following runtime error in above highlighted code:
Arithmetic overflow error converting expression to data type datetime.
Is it possible to update and edit a record in Formview at the same time. Currently, the formview's default mode is set to Insert where users can add a new record to an SQL database, however, when that record is added I need that information to update another table all on one click. Is this possible with a stored procedure or a button that allows both?
View 4 RepliesI have a formview tied to a gridview. The formview shows the data for the row selected in the gridview. The formview is invisible by default , default mode is readonly and becomes visible only on Selecting a row in the gridview. I make it visible in the SelectedIndexchanged event of the gridview. There are Insert and update buttons present outside the formview which perform the insert and update using code-behind. The code is below.
AFter an insert or update, the formview makes invisible again. I want to show the formview with the newly inserted or updated row in Read-only mode. How do I do this?

I have Gridview that opens in the Edit Template with UPDATE and CANCEL links at the bottom, so the users can modify records.
When the user clicks UPDATE there is no indication that the DB was updated. I don't want to redirect the user.
What is the easiest way to provide a confirmation that the DB was updated?
Im having a problem with a datetime conversion using a formview with a nested wizard. The senario is I the user can add to the database allowing for null datetime values. The code below work fine on an insert query, but when the formview is in update mode the conversion fails.

It is a header with two columns: On left column there is a TreeView, and on the left there is nothing (now there is a label to try the thing that I want to do).
When user select a node on treeview a click on Edit button. Code for click event is:
protected void Edit_Click(object sender, EventArgs e)
{
if ((DestinationTree.SelectedNode != null) &&
(DestinationTree.SelectedNode.Depth > 0))
{
BaseControl baseControl = new BaseControl();
UpdatePanelRight.ContentTemplateContainer.Controls.Clear();
switch (DestinationTree.SelectedNode.Depth)
{
case 1:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control1.ascx");
break;
case 2:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control2.ascx");
break;
case 3:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control3.ascx");
break;
}
UpdatePanelRight.ContentTemplateContainer.Controls.Add(baseControl);
}
}
Depending on node selected depth is going to load a custom control dynamically. It works, but when the user select another node on treeview, the original label is reloaded on right column.
I have a Formview control that has several lookup fields. The value is an int ID but the textfield is the name, e.g. value = StateID, displayed text = StateCode)
If the user leaves that field blank, I get a Server Error when attempting to Update: Failed to set one or more properties on type orgOrganization. is not a valid value for Int32.
In the table for the LinqDataSource which provides the data for the Formview, all fields except the text field OrganizationName allow Nulls.
Does anyone know why this might be happening? I tried a test which just has the numbers, no lookups, and get the same result.
