Re: Custom control for FormView?

11-Jul-08 8:49

I have a need to enter names and addresses throughout a web application. How can I create a control (C#) that I can include in a FormView control that will allow names and addresses to be entered with the fields bound to a datasource via a Formview Template?

My code is

public void Insert()
    {
        string query =
            "INSERT INTO WordTable (Word_ID,Word,Help) " +
            "VALUES (@Word_ID,@Word,@Help)";
        SqlConnection conn = new SqlConnection(cs);
        SqlCommand cmd = new SqlCommand(query, conn);
        cmd.Parameters.Add(new SqlParameter("@Word_ID",this.Word_ID));
        cmd.Parameters.Add(new SqlParameter ("@Word",this.word));
        cmd.Parameters.Add(new SqlParameter ("@Help",this.Help));
        conn.Open();

Try executenonquery instead of executescalar.

scalar is for a select statement, it returns the first value of the first row.

I didn't get any requirements for the signature

I am trying to change a LinkButton to disabled/enabled:

LinkButton newNext = (LinkButton)DataList1.FindControl("NextHyperLink");
newNext.Enabled = !pdDataSource.IsLastPage;

this will not work.. it returns that newNext is null...

The linkbuttons are in the HeadTemplate of the DataList1??

Problem is seems like where you are calling Find Control.

Datalist contains more that one items so you will need to provide specific item.

Can post here code that in which you are calling ?

In which event you are trying to access?
If page load i think you cannot...

Try by accessing in the ItemDataBound event... by using e.Item.FindControl

EVEN THE WORD IMPOSSIBLE SAYS I M POSSIBLE.

The problem was is I was trying to access a LinkButton that was in a DataList and that DataList was in another DataList... (one datalist was in the Headertemplate of another datalist)

Still wonder how to do that though??

Thanks for the information.

I have following regular expression to check HH:MM:SS format of the text box.

^([0-1]?[0-9]|2[0-3]):([0-5]?[0-9]):([0-5]?[0-9])$

I would like to give the flexibility to the user to enter the data in MM:SS format too. I was trying to modify the above regular expression to validate for the MM:SS format too. but didnt get the success.
can anyone please help me to build the regular expression to allow user to enter data in HH:MM:SS and MM:SS format too.

Thanks a lot.

How to edit FormView Templates in WYSIWYG mode?

equalizer70011-Jul-08 5:24

Re: How to edit FormView Templates in WYSIWYG mode?

11-Jul-08 5:24

Using Visual Studio 2005, when I edit a FormView template it is not presented in WYSIWYG mode, but is reformatted to about half-column size. Is there a trick to being able to edit a template as it will actually look? It looks correct when not in template editing mode.

Herman<T>.Instance14-Jul-08 20:04

Re: How to edit FormView Templates in WYSIWYG mode?

14-Jul-08 20:04

VS 2005? Do you use C#, VB, ASP.NET, J#?

Could you be more specific?

equalizer70015-Jul-08 4:01

Re: How to edit FormView Templates in WYSIWYG mode?

15-Jul-08 4:01

Sorry: C#, VS 2005. When I go into template editing mode the templates are only about half the width of how they display when in non-edit mode. This makes it very hard to get the templates right. The same thing happens with VS 2008.

Re: How to edit FormView Templates in WYSIWYG mode?

15-Jul-08 5:20

can't you use a property like ItemStyleWidth or ControlStyleWidth

equalizer70015-Jul-08 7:08

Re: How to edit FormView Templates in WYSIWYG mode?

15-Jul-08 7:08

The WIdth property of the FormView conrol is set to 100%. The templates (Edit, Insert, Item, etc) do not have a property sheet that I can find.

The templates display correctly when youo are not in template editing mode, but when you go into template editing mode the width of the Formview shrinks by about 50%, even though the Width property has not changed.

Each control, like Label or Checkbox have WIDTH properties. What changes for you if you set these ?

equalizer70015-Jul-08 7:58

Re: How to edit FormView Templates in WYSIWYG mode?

15-Jul-08 7:58

Yes the code is similar but the data is from a datasource and there is no Item template. Some of the controls have width properties set. The width properties do not seem to take effect in template editing mode but when not in template editing mode they are fine. The width of the item template is set to 100%, as is the width of the FormView. I have a table wrapping the contents of each template, and the table width is set to 100%. If I change the width of the table to something like 500px, the template editing mode expands to hold it. But I am trying not to use fixed width tables. When not in template editing mode all the widths are correctly displayed as 100%. They are only squeezed up in template editing mode and only if the widths are set to a percentage.

LOOKS like you have found a feature in .NET.
Is a GridView not a suitable component for this?
