Advice wanted re: sizing datagrid optimally

Member 9617-Jul-06 18:57

I'm curious to know what the best practice is for sizing controls on pages. For example I have a 3rd party DataGrid-like component that, if I leave at 100% height will go as big as it requires to display all the rows returned which in turn means the user is required to scroll the frame it's in if they want to see the whole result set.

(yes I said frame Smile | :)

, I've researched this to death and a frameset is still the best fit for this particular job)

However that component has a built in scrollbar which works well when the grid is restricted to a smaller size. Where it would normally take 3000 pixels vertically to display I could set it to a height of 300px and using the built in scrollbar scroll through the results to the last row.

Ideally I want to exactly fill the "content" frame with as much grid as will fit perfectly and use the grid's built in scrollbars for navigating to the bits that don't fit. This though, seems impossible. Short of someone replying with a magic solution that I just couldn't find I'm guessing I'll have to compromise.

Every example I see seems to favor setting explicit sizes in pixels for many data components.

So should I just pick a "typical" browser window size and set explicit values for that size (i.e. assume minimum 800X600 and smaller size users can scroll)?

This seems lousy though when considering that many users have a much larger size than a default minimum and would end up with wasted real estate on screen, so is it better to go for a maximum and set explicit sizes for that maximum and then anyone with less has to scroll the frame?

Neither sounds very nice but the minimum sounds the least annoying.

I've messed about with some Javascript to dynamically resize the grid component, however there doesn't seem to be a reliable way to get the size of the browser window that works in both FF and IE so I'm not really planning on using that method. I can reliably get the entire screen dimensions but that's pretty much useless.

Help...so confused.. Any and all advice gladly accepted.

Hi Sathiya,
Are you generating temporary class in your web service code? if yes than it may be referring some hardcode location for generated cs file as i can see from the error message. solution is try to trace some hard code path or provide some specific location for temporary generated class

Swap.

DataTable.Rows.Count

This assumes that you are binding a DataTable to a DataGrid. But if
you're binding a DataReader this approach won't work.

==========================================================

Another way RcdCount = DS.Tables("pubs").Rows.Count.ToString()

Hi there,
You should remember that the TextBox does not have the DataSource or DataSourceID properties as the DropDownList, however you can use the data binding expression to bind to the Text property of the TextBox. It looks something like:

<asp:TextBox runat="server" ID="TextBox1" Text="<%# your expression goes here %>" />

and you need to call the DataBind method.

Some mail servers do reverce dns lookups on the domain where the message originates or check for MX records for that domain. If your SMTP service isn't set up properly some mail servers may reject mail coming from it.

You could use regular expressions to see if the array contained only numbers or not. Create a loop to go through the array.

One time in college I think we did it by looping through, converting each character to the hex format and checked that against a list of hex values that were numbers.

In VB you can use IsNumber, although you will be mocked by c# types.

Simplest way is to TRY to parse each int, and catch FormatExceptions...

+ Use the pubsConnectionString with the p as lower case.
+ Double check if the database pubs (Initial Catalog=pubs) exists in the specified server (Data Source).

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
