I have a formview bound to an entitydatsource and it is working fine. here's the scenario though
If the querystring contains a "memberID" , I have setup an object datasource to fetch the results corresponding to the memberid from the database.
I want the name and email id fields in the formview to default to these values in the objectdatasource. How can you do this?
I'm using an edittemplate to handle both editing and inserting for a Formview. In Insert mode, the Identity parameter is not needed (and cannot be used in the parameter list). In Edit mode, I need the bound value to know which record to update. So, what I tried to do is set the Text property in the OnDataBinding method.
[Code]....
The result is that the field is bound for Insert anyway, shows up as a parameter, and my insert statement fails (since this extra field messes up the field order of the parameters). Plus, it is always null in Insert mode by definition.
Is the OnDataBinding method too late to clear the property? If so, where can I do this, since PageLoad is too early (the template has not loaded yet and I cannot Findcontrol the field. Or is there a better way to handle all this?
I 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)
{
}

1) How to bind this xml Using DOM Model to GridView from serverside? I don't want to pull xmldatasource and gridview with columns on FRONT end(aspx).
2) How to dynamically bind the nodes DesignDate, SoldDate....as columns to Gridview, coz there can be many columns with different column names and I don't to specify by saying: HeaderText="DesignDate". I would like to generate this dynamically from serverside.provided with a code to make this working.

This is how it works for a radio button list in a formview insert template.
I have a FormView which will bind values from the database using a ID parameter from queryString. In my database, I have a field named CategoryList which can store multiple CategoryID (From Category table) in CSV format (eg: "1,3,4,5"). I'm using SQLDataSource as my datasource.
So, I want to show the selected category in CheckBoxList. Meaning that, the checkbox will be checked (on page load) if its ID is in the CategoryList. Also, I want to allow the user to check/uncheck the CheckBoxList and updates to the database in CSV format. How can i do that?
I have a dropDownlist in a Formview Edit and Insert Template that is Bound to a Field, It is for a credit card expiration date, so I want to programatically populate it so it will automatically show the next 8 years from this year. Works fine!
Except When I add it to the Formview, and click on edit it gives me an error basically saying my record does not match the list item data, but it should since it shows the year just fine. So I am figuring that it is not binding the ListItems to the dropdownlist.
I have tried every event I could try and I always get the same error. I have tried the ModeChanged, DataBound, DataBiding, PreRender, Load on both the Formview and the DropDownList, but no go. How do I do this?
[Code]....
This works fin on a DropDownList that is not in a FormView, so I know its not the Code. and the record I am updating is 2010, so the record is not out of range
I have a sql-bound formview with three DDL's bound to individual SQL datasources. In edit mode, I want to set the selected value to the formview's value, and this works:
<asp:DropDownList
ID="ddl2"
runat="server"
DataSourceID="ddl2lDS"
DataValueField="Name"
SelectedValue='<%# Eval("Name") %>'
/>
But it only works when there's a match between what's in the formview's DS and the DDL's DS.
Unfortunately, there may be instances where the the formview's DS may return a null value or a value different from the DDL's datasource...and when that happens I receive a compilation error like:
'ddl2' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
What do I need to do to trap that condition before attempting to set the selected value? Do I need to set the selected value of the DDL in formview's dataBinding or dataBound event, by looping through the DDL and checking for a match first?
I am trying to display data in a formview based on the value selected from the drop down list. FormView does not respond or display any data.

im learning webforms and asp.net in general and what i have so far is a formview that displays data being pulled from a sqldatasource, but i also want a checkboxlist that can be used to input information and display information. this checkboxlist is insode the formview. the problem im having is that my formview is calling a datasource with an specific stored procedure with one table and my checkboxlist needs to called another stored procedure that has a different table. formviews does not allow you to have tow different datasources so how can i make this possible? ill paste the front end code and the backend code so you guys can see what im trying to do.

I select a item from gridView and trying to show/update/delete in From view. In Form View I am using the dropdownlist filling it in Code behind. Then i bound the list. But the problem is it is not showing the slected value. Here is the code

AutoGenerateColumns="False"
Width="525px" PageSize="20" DataKeyNames="intPKCountry_DetailID" [code]....
I have a label inside a formview that is not bound to anything.
Lets say I have a table of customers (with a key field called CustomerID), and then another table that has all their orders (with amount spent per order (OrderID) - based on CustomerID)
On the FormView there is a key field (CustomerID) (this is to be used as an INPUT parameter to a SP - which is to return the SUM of all the customers (Order_Totals). I could nest a view within a view I suppose to get this result, however, I just want a label to simply show this ScalarValue.
Basically, I want the label to show the aggregate (SUM) total amount each customer has spent on all orders. I have a SP called SumCost with two Fields (one a grouped by field CustomerID and the other a Summed Total of each customer's orders SumCost)
SELECT [SumCost] FROM [SumCost] WHERE ([CustomerID] = @CustomerID)
I test my SP and it works great, returning the value based on CustomerID - no problem.
My problem is getting the CustomerID passed into the SP on runtime (do I put it in FormView2_Databound) and putting the value into the label (CustTotalLbl) which is inside this form.
In an vwd2005 aspx page, I have a formview, dropdownlist and 2 sqldatasources. My markup is below
[Code]....
When the dropdownlist causes the postback, the formview does not display the data (it's there, I've double checked using query analyzer). Also, the OnIndexChanged only makes a button visible and has nothing to do with the data. What am I missing?
FormView custom data binding problem
View 7 RepliesOkay, here's something that I could easily do the hard way and manually wire up each form element and save it to a datatable in memory, but there has to be a more efficient way to do it.
Here's what I have:
1. A strongly typed datatable and tableadapter in a XSD name Orders
2. A formview control which currently is connected to an ODS connected to the Orders tableadapter, this makes it easy to wire up the databindings for each form field in design view
I would like to:
- bind the the formview to an instance of the strongly typed datatable, and then save the dt to a session object without interacting with the actual database
- load forms on subsequent pages from the dt in session
- ultimately save the dt info to an actual database table on the third page
I've read some solutions where a custom class is created, but to me this seems like almost as much work as wiring up the form field to the table columns manually in code.
how to set a RadioButton List control's ListItem to True or False based on the Databound field?
I tried using Selected='<%# (Bind("multiple_line_required") == "Y") ? true : false %>' but it threw an eror saying that it is not a databind control.
For example I have this control in a FormView:
<asp:FormView ID="AddOnsFormView" runat="server" DefaultMode="Edit"
ondatabinding="AddOnsFormView_DataBinding"
ondatabound="AddOnsFormView_DataBound"
onitemcreated="AddOnsFormView_ItemCreated">
<EditItemTemplate>
<asp:RadioButtonList ID=RadioButtonList1" runat="server">
<asp:ListItem Value="N" Selected='<%# (Bind("multiple_line_required") == "Y") ? true : false %>' >No</asp:ListItem>
<asp:ListItem Value="Y">Yes</asp:ListItem>
</asp:RadioButtonList>
<asp:TextBox ID="AmountTextBox" runat="server" Text='<%# Bind("amount") %>' />
<asp:TextBox ID="AmountTextBox" runat="server" Text='<%# Bind("quantity") %>' />
</EditItemTemplate>
</asp:FormView>
My issue is that , need to change the column name(following some format) of the gridview (which is binded with XMLTextReader). Without changing directly XML file, Required to change the column name dynamically at runtime .

I have a textbox in Formview inserttemplate and I want it be invisible on click of a button.In Visual Studio the intelligensense for this textbox does not show up at all - meaning it is not accessible. However, the control eg textbox OUTSIDE the Formview is accessible.How to modify the code so that we can modify property of a textbox WITHIN inserttemplate WITHIN the formview ?
View 1 RepliesI have a GridView with an TemplateField:
<asp:GridView runat="server" ID="gvReport" ondatabinding="gvReport_DataBinding">
<Columns>
<asp:TemplateField >
<ItemTemplate>
<asp:Label runat="server" Text='<%#Eval("answers") %>' /> out of <asp:Label runat="server" Text='<%#Eval("questions") %>' />
</ItemTemplate>
</asp:TemplateField >
</Columns>
</asp:GridView>
What I'd like to do on gvReport_DataBinding is change the field the Evals point to, so I end up with something like:
<asp:Label runat="server" Text='<%#Eval("answers_foo") %>' /> out of <asp:Label runat="server" Text='<%#Eval("questions_foo") %>' />
I have gotten this far:
TemplateField tf = ((TemplateField)gvReport.Columns[0]);
But I'm not sure what I should be doing with tf. tf.SomeProperty.Replace("answers", "answers_foo")?
Or am I barking up the wrong airplane on this one?
I have a gridview that has certain values in it that I would like to change based on a condition. For example, if a value in the column is 'x', I would like to make that Value Bold and have text that says 'Not applicable'
How can I do this? How can I programtically chnage values in a gridview?
Here is my GridView
<asp:GridView ID="GridView1"
I have a need to change the image (bound) in a gridview after it has been databound. Basically i need to assign a photo to a record and I want to change the image url for that row. I can change the text in any of the cells of the row but I can't seem to find property for the imageurl.his is what I do to change the text(cell 5).
int index = int.Parse(Session["NSI"].ToString());
GridViewRow row1 = GridView1.Rows[index];
row1.Cells[5].Text = "just some text";
But now I need to change the image url for cell 0something along the lines of ...
row1.Cells[0].ImageUrl = "~imagesphotos12345.jpg";
I don't much care for the template rigmarole of the ASP.NET FormView web forms control. It seems the only way to access template defined controls is to 'capture' module level references to the wanted controls in the ItemCreated data binding event, for use in other tasks and event handlers. Ideally I would just like to be able to call set this.DataSource and call this.DataBind on a page, but only the latter is possible through inheritence, and doesn't achieve any of my normal data binding needs. What else is there besides the hairy, scary FormView control?
