Web Forms :: Length Checking In The Form?

Oct 30, 2010

In my application, if I do not input the value into the textfield, it will show error message: "The value '' is invalid."

However, is it possible to check one more thing: the length of the textfield? For example, it will show the error message if I input more than 10 chars? And is it possible to change the message "The value '' is invalid." to "Missing Value"?

Allow Users To Enter A Variable Length List Of Items In Form?

Jun 15, 2010

I need to let my users enter a variable length list of items into something that looks like a grid view (or a series of standard text boxes stacked vertically). Each item could be a few characters or a few hundred characters long, and I just want them to enter a "sentence", and then tab to the next row, and always having another blank one ready to go at the bottom of the list.

I don't want to save any data to my SQL Server DB until they enter the entire list and then click on a "save all" button. When they hit the "save all" button they will be given a preview screen where the data will be presented as standard HTML ordered list. If they confirm/save, then each row of the grid will then be saved as a separate row into my SQL Server database (with an index to remember the order).What ASP.Net (or Jquery/javascript) UI control would be the best to use in this situation? (i.e. just for the data entry part - the rest I got covered).

Web Forms :: Reduce The Length Of .net Generated Control ID's?

Aug 25, 2010

I'm looking for ways to reduce the size of my page . I have a page that just renders a gridview - no images - and it is over 400k!

Looking at the html that is generated I see the names of the controls in the gridview are very very long. For example: ctl00_ContentPlaceHolder1_releaseGV_ctl149_lblBuy

My gridview is about 200 rows by 13 columns = ~ 2600 spans with very long names rendered. The above example is 49 characters X 2600 controls = 127,400 characters just in control ID's!

The actual data on my page ins't anywhere near a tenth of that!

I am already storing viewstate on the server.

YES, I will put a pager on this page to bring down the number of rows. Also, I've seen sever other posts related to page size with some excellent content. I will follow up on them - however I have not seen this specific question answered.

Here is a sample of my page. As you can see there is not much data and a lot of html!

Web Forms :: Dynamic Javascript -display The Length Of Textbox1's Value?

Nov 26, 2010

When the box is checked, I want to display the length of Textbox1's value. The problem I encounter with the code below is that it gives error about object not found. It cannot find TextBox1 object. I try to replace document.forms[0].TextBox1.value.length with MainContent_TextBox1.value.length or with document.getElementById("TextBox1").value.length or with document.getElementById('<%= TextBox1.ClientID %>').value.length but none of those works. They all give the same error about Textbox1 object.
