Forms Data Controls :: Required Field Gridview?

Jan 19, 2011

If Session("location") = "HOME" and DropDownList3.SelectedValue = ("5") then
"fieldinmygridview" cannot be null (i.e is required)
end if

Forms Data Controls :: A Required Input Field DropDownList If Old Records Have Null In This Field?

Apr 1, 2011

I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .

I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList

<asp:DropDownList ID="DropDownList_HP" runat="server"

AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...

This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help

http://msdn.microsoft.com/en-us/library/ms366709.aspx

So I changed the ListItem in the DropDownList markup to the following:

<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"

AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...

This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.

In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.

Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".

Data Controls :: How To Add Required Field Validator To TextBox Inside GridView

Mar 26, 2013

in my module there are data of students for H.S.C., C.E.T, AND H.S.C+C.E.T. so when i run the gridview page all the data of all streams together is displayed so i sort the data using a dropdownlist...means if 1 select the H.S.C in dropdownlist only the H.S.C students are being displayed.so the problem is when i sort the data by selecting a stream in dropdownlist at that time the error message  of required field validator is displayed...

1) I wil select the stream from Dropdownlist and click the "sort button"

2) After the data is been sorted and i will enter the values in    the TextBox  and if i'll miss any of the textbox blank and i click on the "submit button" after dat the error should be displayed

Web Forms :: Gridview Update Not Firing With Required Field Validator?

Feb 17, 2011

I have a gridview that contains a textbox, a drop down, and a checkbox. The commandfield of the gridview has ShowEditButton="true". All of the gridview updating takes place in the "_OnRowUpdating" event. I have a Panel above the gridview with a table and some fields. Everything in the gridview works perfectly, the edit, the update etc., however, when I add a requiredfieldvalidator to the panel above the gridview, the gridview update functionality no longer works. e.g., clicking the update button does not appear to fire. If I comment out the requiredfieldvalidator, everything works fine.

Web Forms :: Required Field Validator Not Catching Empty Field?

Feb 3, 2010

I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.

The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.

The nested ascx control is a repeater control and this may be the reason, but I am unsure.

I'm not exactly sure what question to ask, but I'll list a few below.

How do I attach the field validators up a level to the 1st ascx control?

Is it possible to put required fields into a nested ascx control?

DataSource Controls :: Storing Required Field Names In Web.config?

Feb 2, 2010

I am writing an app that has a bit of process flow to it. On the save of a record, I need to check some fields to make sure they are not null. If they are not null, I will update a 'SectionComplete' field to true.

The thing is, I would like to store my fields in the web.config. So, I would like to have a string in the appsettings section that has a list of field names that are required. Then in my method, I would call these fields out and check each one for the specific record id, and then update the database.

I would like to do this in the web.config so we could add/remove columns without having to redeploy.

For example: my required fields are name, id, and phone. For section one to be labeled complete, all of these fields would need to be not null.

web.config would have this entry:

<add key="Stage1Fields" value="name, id, phone"/>
