What is the reason behind showing 10,000 records in Dropdown list?
Use some filter criteria to minimize the number of records. You can also use data caching to read data from cache rather than hitting the database every selected index change.

I am a beginner in this language; I would learn to use Zedgraph and I need
information about installing zedgraph. Until now I never installed third
part components. How can I begin ? Thank you

First of all, if you're a beginner, you should learn the language before worrying about third party components ( or even ASP.NET IMO ). Second, you obviously are more than just a beginner, you are completely lost and uninformed. I hope against all sense of reason that you're not doing paid work, because if you are, it is a disgrace.
you can't use a winforms library in ASP.NET. Just like you can't use Ford spare parts in your Toyota. They are not compatible.

Causing you are almost a psychologist, I confirm you : with asp.net 2.0 I am almost a beginner :
I usually work on desktop applications, using Delphi.
Since last september, once in a while I study and work (paid) with Visual web developer 2005/
Visual Studio 2005. I am doing a prototype to see by web, some datas seen by client-server applications.
It is a project of 5 web page. You surely have understood it should be done on economy.
Now I am searching for doing simple plain diagrams (two dimensions) and I thought Zedgraphs was good.
Do you know form where could i begin (for this arguments : plain diagrams).
Thank you

I would like to set the textbox maxlength property in code based on the field length in the table.
For example: The table field is a varchar(10). I query a record from that table and set the value of that field to a textbox text property. How can I look up the field length in the table and set it equal to the textbox maxlength property?
|
|
|
|
|
just set the max length property of that textbox=10 then u can solve your problem
|
|
|
|
|
I want it to be more dynamic, so if the field length in the table changes the code will not have to change.

try DataTable...Columns Property
|
|
|
|
|
Ok thanks, but it always returns -1.
mytable.Columns["field1"].MaxLength
|
|
|
|
|
I'm not sure why that would be unless you haven't connected to the database.
|
|
|
|
|
I queryed the records into a datatable using a stored procedure. The table does not have any columns before the query. Afterwards it should inherit the column properties from the table on the DB.

I am using GridView1 to populate records. But I have problem with Rows height of GridView1.
When GridView1 has more than 10 records then GirdView1 rows height is normal. But when the record count is one...Then Rows height goes bigger and bigger...
How to fix this issue?
|
|
|
|
|
What is the height property of the gridview?
Make sure the height property of your gridview is not set or blank.
If you don't want the grid to be more then a certain height put it inside a div tag and set the height of the div.
I didn't get any requirements for the signature

|
|
|
|
<br />
div style="max-height: 300px; overflow: auto; width: 600px; height: 300px" <br />

You Can set the Row hight property also ....
