I use ObjectDataSource and FormView for Editing of table data. Fields of table are to be edited by a few users.I use common page using ODS and FV (EditItemTemplate with a table) and want to succeed above purpose by allowing relevant fields to respective users.By searching through Google, I use table row's visible property like below
<tr id="Row1" runat="server">

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 have a gridview which has editable columns.
The gridview lives in a formview, which lives in another formview.
Inside one column is an end date. This column has a textbox which gets it's value when I choose a date from a calendar control. However, when I choose a date from the calendar control, the program crashes instead of populating the text box.
Here is the page and the selectedIndexChanged sub for the piece of work I'm trying to accomplish...

This is probably a dumb question, but I have to ask because I spend so much time editing my formviews and listviews. Is there a way to edit the default template setup for these controls, in the code or somewhere? When you drag them over you get the default text with textbox column names; then I spend over 30 mins editing each to look the way I want it to.
I know I can create standard templates for WebForms and save them as Exported Templates.
And is it possible to edit the default control when you drag them on to the page, to list certain attributes automatically. example (validation controls you always have to add ControltoValidate I would like to drag mine onto the page and it say controltovalidate="" and then all I do is fill in the blank. Intellisense is fine, but sometimes you get brain freeze after hours of web design and forget the needed attribute and you have all to go through all of the errors and mistakes.
The ultimate would be, to drag a FormView Control and when you Refresh the Schema, you get textboxes, label controls instead of text for column name, and divs for forms, and Image Buttons , I am sure there is an XML file that runs the code that you can edit or something.
OR
ASP Developers, When you develop the next ServicePack allow us to edit or create default templates to customize the default templates, in VS and VWD.
This might be confusing but ill try to explain the best as i can. I have a gridview that get the data from datatable. This is simulation my grid view.

I am somewhat new to ASP.Net and the interesting ways to build forms that edit data. I am working on a FormView and have come to a hurdle that I can't seem to figure out how to get past.
This link will open the form and a dummy record where ID=2. [URL] ....
The ID is the variable to open a specific record. That's pretty obvious. Clicking the Edit button switches the FormView from ItemTemplate to EditItemTemplate. My problem is that after changing some values then clicking Update, the record is not updated.
I need to have the record updated and return to the ItemTemplate view. I believe there are issues with the fmvData_ItemUpdating and fmvData_ItemUpdated functions. I am not sure what has to go in there.
I also want the Inspection Date field to be formatted to mm/dd/yyyy when switching to the EditItemTemplate.
My TableAdapters are creating using the App_Code/DataSet.xsd method.
I am using Eval("fieldname") in the ItemTemplate for values and Bind("fieldname") in the EditItem template.

View 6 RepliesI'm amazed that it took me minutes to figure out how to retrieve text from a specific SQL database record and display it on my aspx page using FormView---and yet days later I still can't figure out how to retrieve/display the corresponding database image...(I feel like I went to a fast food restaurant, received my burger and drink in minutes---but for the fries I'm told to leave the restaurant, drive to another county, and search for the granite boulder under which I am to find the next clue in the quest to get my fries.
I don't want to waste anybody's time---I do see that this issue has come up here before (but each solution seems more complicated than the previous one): clearest way (or your favorite past thread on this topic) to retrieve/display/edit binary image data using FormView?
I am using a SQL DB to save and display a simple collection of data which contains several dates. As the intended audient is UK based, I wish to display the dates in a UK format (DD/MM/YY). This works well (using {0:d}) and the display and creation of records also works fine.
However, as all fields are editable, when the record is displayed in the Formview edit mode and saved, the dates field try and save in the UK format and will more often than not fail with an invalid date error. How can I display the date in a UK format yet get the same field to save in the usual SQL date format?

I'm receiving an error when I write some text in a text box then use a button to display the data in a form view after it finds the record in the database. Other word, I have a textbox as a search then the button to search the database to display the results in a form view. I do have an autocomplete in ajax which comes up with the correct information. The following is my code. For some reason its not working. Instead I get the an error.

I have an asp.net c# web forms application with a formview. When I click "Edit" on the formview, I have set the focus to a textbox. This works just fine.
protected void fv_comp_status_list_DataBound(object sender, EventArgs e) {
if (fv_comp_status_list.CurrentMode == FormViewMode.Edit) {
TextBox tb = (TextBox)fv_comp_status_list.Row.Cells[0].FindControl("pol_numTextBox");
tb.Focus();
} }
The problem is that the textbox is at the bottom of the screen. I want to set focus on the textbox and also have it move (scroll) to the top of the screen. This will allow the user to see the entire form, withhout having to scroll initially.
How can I modify the code to set the textbox (pol_numTextBox) at the top of the page on DataBound once the focus is set?
I wish to add a sub to vb file that changes the display value of several asp:panels located in a Formview Item Template. My only question is what is the proper event to run this in. (databound, item created etc...) If it matters this formview appears in a Gridview Item Template.

I need to add a check for a checkbox column in the grid. Something like:If CDate(e.Row.Cells(6).Text) < Date.Now and 'checkbox is checked' Then make another colorHow do I check for the value of the checkbox?
EXISTING CODE:
<asp:HyperLink ID="HyperLinkG102" runat="server" Visible='<%# (Convert.ToInt32(Eval("L_ID")) != 77777 ) %>' Text='<%# Eval("L_GalleryName") %>' NavigateUrl='<%# String.Format(".... /findlink.aspx?linknum={0}", Eval("L_ID")) %>' Target="_blank" Font-Size="9"
ForeColor="Blue"></asp:HyperLink>
Is there anyway to put an OR conditional in the Visible text?

I have a gridview on my aspx page. I know we can format gridview row in rowdatabound() of gridview. But my problem is bit different.
In my gridview, i have a column customer code, a single code can repeat more than once successively. I want for one customer code, row color should be blue and as soon as code changes colour should be yellow for that code. Similarly when code changes again color should be blue again.
In this way color of my gridview rows should be blue and yellow alternately based on my customer code.I have arranged customer code in order by using sql order by clause.
I am using a column named "bk_End_Date" in my gridview.I want to change the row color based on a condition.i.e. if the date value is within one week of today's date (upcomming days only), it's color should be red.I tried following method in RowDataBound Event of C#
//if (DateTime.Parse(e.Row.Cells[5].Text) <= DateTime.Today.AddDays(7))
//{
// e.Row.BackColor.Equals(Color.FromName("Red"));

I have a conditional Eval statement in a Gridview that returns a boolean result to display an image if two datafields(strings) are identical:
Visible='<%# Eval("customerA").Equals(Eval("customerB")) %>'
Works great except I don't want the image to display if both datafields are empty. How can I add that logic into this Eval stmt?
