i've created a webform with one gridview having connected with the database using datasource. i.e password database with three colomn .
now want to insert the custom dropdown button using server control for each column.
when i select the dropdown list the list should display the value as required.
e.g if i click the uname dropdownlist then it should show the list of names.
if i click on pwd dropdownlist then it should show the list of numbers.
if i select any one of the value in the dropdown list then it should insert into the
database.
can i get code on this type of question...?

here's a situation and I would appreciate your response.
I have programmatically created the Wizard control:
Page_Load(obj s, evargs e)
{
Wizard ClaimDetailWizard = new Wizard();
foreach(int item in selectedItems)
{
//create new step
//added custom control to new step
//add step to wizard
}
//added wizard to a placeholder on a page
}
Based on List I get from Session i added new steps to my wizard To each step I had added a custom control
Each custom control in tern contains another custom Gridview Control in it.
So here's the problem when the page loads for example for two steps. All is good Wizard does what it's supposed to do.
But when I try to use sorting or paging in that custom Gridview. Somehow it displays the gridview I should see in the next step of the wizard.
Also what I'm noticing through debugging. Is that when I press next in the wizard I go back to the original page where I do all of the code specified above, and it recreates the wizzard. But it goes to the next step. Is this the way wizard supposed to work? Just doesn't seem very efficient.

I'm working on a website to showcase some of my bird photography, using ASP.NET 2.0 and C# with a SQLServerExpress backend.What I have right now is a ListBox bound to my database that displays a list of common names of birds and when the user clicks on an item in the listbox the main image on the page is changed to the image for that bird. For style reasons I want the listbox to always be a fixed size and because I specify the size (using CSS) a vertical scrollbar appears. My problem is that I want to provide my own images of arrows that go above and below the box such that when the user hovers over an arrow the box scrolls slowly and when the user clicks an arow the box scrolls quickly. Finally, my main problem is that I want to get rid of the ugly default vertical scrollbar that comes with ListBox.
Can you guys help me figure out how to do this? I don't mind using a different control other than ListBox as long as it is available in ASP.NET 2.0 and as long as it can be bound to my db. I also don't mind using JavaScript (which I'm sure I'll end up doing for the hover effects). Right now I'm fooling around with subclassing the ListBox control but I've never subclassed a control before so I'm somewhat clueless.

I'm trying to extend de GridView control with a Custom Server Control, I'm doing ok with extended properties but when I get to methods that need to re-apply or modifiy the DataSource I don't get any data in the grid, though the SQLDataSource actually retrieve data. Here is my MyGridView.applyFilter() method, which should filter the data but actually shows an empty GridView, but as I sayed, the DataSource has data. I try to find (FindControl) theSQLDataSource of the GridView (Me) and modifiy its paramters, thenDataBind Me to apply the changes...
[Code]....
What am I doing wrong? why is the gridview empty?

I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.

I'm trying to extend the GridView into a custom/user control "WorklistGridView". And I'm not quite sure how to do it... so here's what I need:Every row needs to have a control (either a boundfield or a templatefield with a label, etc.) that contains the StepID (which is a column returned in the data set).I want to be able to use the WorklistGridView as a base class and extend it to something like "XyzWorklistGridView", where that child class would have a few more controls in the row template.

created a Custom Textbox Control that is intended to be a "masked date" textbox, so that I can handle different ways a user might enter in a date and make it work no matter what.I did this by creating a custom control with 3 separate Textboxes one for month,one for day one for year,then do some handling for different things that could be entered and it would all work.
The problem I am having is,when I add this control to the page,if I do an alert to check the Text value of the custom control it just gives me "[ServerControl1]" even if I enter in a date.
I tried doing an AutoPostback after entering so that it would refesh the Viewstate to have the values of the textboxes but the control doesnt seem to actually postback, even though I have it enabled.accessing the Textbox value after someoen
has entered a date?first custom control I have created and have been using google.
My Server Control Code is as follows:
