If we select the dropdown list Item then I want to display the Item Particulars in the Gridview Please Help me
On the SelectedIndexChanged of the dropdown rebind your GridView off of the selected value
Add a dropdownlist control, a button control, a grid view and an sqldatasource.
Configure the datasource first in sqldatasource.
I would recommend write a storeprodure to fetch data into the gridview (sqldatasource).
Bound the parameter to "controls" and select the dropdownlist. Now your DDL is bound to the gridivew. In his table click on advance properties and change property convertemptystringto null = false. (there property is something similar).
If you want a button to update the grid view, do this. Add the default event control to the button, put no code in it.
If you want to change the grid view content based on select directly then choose autopost on selected changed in properties of the DDL.
If everything is fine, this should populate your grid view based on contents in DropDownlist

I have a grid view of devexpress control.
In my grid view i have ID,ITEM and Checkbox.
Now my issue is to add grid view items to listbox when i checked a check box in grid view.
Please help to sort this issue.
The devexpress gridview should have an event triggered when checking the checkbox.
So it would be something like this pseudo code:
Handle gridview.checkbox.valuechanged e
id = GetID(e.row)
item = GetItem(e.row)
itemAlreadyExists = ItemAlreadyExistsInListView(ID)
If e.Value and not itemAlreadyExists then
_listView.Add(id, item)

I guess you have a list which you use to bind in the DropDownList.
Look for the SelectionChanged event, when the event is fired you can use the SelectedIndex to use in your list and get the value you want.
I have a table called Vendor that has two columns: VendorNum & VendorName.
Is there a way to create a list or a listbox or a listview that when a button is clicked, this vendor list will pop up. Then the selected popup list's row will pass the selected VendorNum into a textbox that's in the parent page..
I only know GridView has the select row option, but is it a proper way to put the gridview into a Listbox so the list can be scrolled up/down all within a fixed box?
You might want to take a look at the ListBox.SelectValue and/or ListBox.SelectedItem properties
I have a ComboBox with the values "open", "closed". According to values changed in the ComboBox, I want to change the DataGrid to display either "open " or "closed" values. How can I do this?
Your DataGrid can be bound to a DataView. Create different DataViews depending upon the Selected item in the DropDownList (here's an article on how to retrieve the selected item).
Fill a DataTable with your data. Derive different DataViews for the combo states. When the combo changes (enable AutoPostback), select the appropriate DataView and Bind the DataGrid.
You could use RowFilter property of a DataView object binded to the DataGrid.
You can use any of the *DataSource controls and add a control parameter with the ID of the combobox. Turn on autopostback for the combo, and asp.net will automatically call the object datasource with the new open/closed value.
