I have a dropdown which consists of all the controls names like textbox , label , combobox , dropdown list...etc.
if in the starting one label control is placed on form,on user selection of control name in dropdown list ,that label control should be replaced with the user selected control dynamically...like this,what ever control user wants to keep can keep just by selecting dropdow
i need the controls to be dynamic.that is only the requirement.whenever a person ,say admin want to change the controls from CMS,he can easily change with the selection.
You'll need to use some Javascript magic for this. Whats the specific requirement?

I want to make a Searchbox, so i want to create a User Control, that display a textbox but when typed on will call a dropdown list similar to that of a combobox. ¿is this posible?
the input that you are describing called AutoComplete,
and WPFToolkit suggest easy to use one

In my asp.net application, I need to be able to dynamically add user controls based on data in a database.
For example, on page1, I will bind three elements to a repeater:
some html content
a user control
more html content.
The repeater on the page is surrounded by an updatepanel
(updatemode=conditional, childrenastriggers=false)
The user control also has it's own updatepanet
(updatemode=conditional, childrenastriggers=true)
So, what I have is something like this:
outer update panel<br/>
repeater<br/>
item 1 = html<br/>
item 2 = user control<br/>
user control update panel<br/>
user control content<br/>
/user control update panel<br/>
item 3 = html<br/>
/repeater<br/>
/outer update panel<br/>
The problem is, I don't get any events fired by my user control. I'm pretty sure I need to create the control in the page_init, but I'm a little unsure of how to do this, since I may have to create any number of user controls of different types, and place them at different locations on the page. Has anyone ever run into this problem before, and how did you solve it?
Steps
Add add a placeholder control to updatepanel.
In CS file create a instance of your usercontrol.
Add that control to placeholder.
I have an autocomplete on my page where I use it as a search. I want to be able to select an item that appears in the autocomplete and then when the user clicks another box it will do a postback and if there is data for the one selected, it will populate the other fields for that chosen selection.
So what I am asking, is how would I go about doing a postback when the user clicks into another textbox on the screen?
Hi you could use event from textbox (TextChanged) inside this event put your code to verify if this data is correct. Don't forget put property AutoPostBack from textbox in True. This action only can be use if the data in textbox change if for example you put
My Dog
and data not exists if you change focus nothing will happen until you change the data for example

I am implementing a custom filter for datagridview.
The custom Filter is a user control which has a textbox that allows the user to enter text.
When the user selects a particular column for filtering, I am adding the filter usercontrol to the Grid controls and then displaying it just below the selected column.
Issue :
When the user tries to enter the filter text on to the textbox, it accepts only numerical values and characters, it does not allow dots or certian characters like !" . however if the user clicks on the delete key, from then onwards the textbox accepts all input characters.
This is probably to do with the fact that the user control is added to the Grid's control collection, and the grid is consuming these events in a different way..?
Any help appreciated.
Don't add the control to grid's control collection, but to the form's or container's collection - Then just call the filter control's BringToFront() when you want to show the control in front of the datagrid, and when done with filtering just call Hide() or SendToBack() so it goes non visible again.
I am creating a Windows forms user control. This control has a textbox and a listbox.
When the end user types text in the textbox, the listbox will appear and filter the data
depending on the text box. The data is set by a datasource.
I have created this control because I want to filter in the contains of data "not start with."
Now after I create the control I found a problem when the list appear it did not appear out of form boundaries.
I change the control size in appear and disappear the listbox. What can I do?
You can not show a ListBox out of the boundaries of its parent Form. What you really wan to do is open a new Form where ListBox is visible.
Hope this helps.
