I am trying to get an ASP.NET 3.5 ListView control to select and highlight lines through checkboxes displayed in the first column. If I use an asp:LinkButton instead of a checkbox, the line selection is supported automatically through the LinkButton's property CommandName="Select". How do I do that with the checkbox?
And as soon as I managed to do that, how do I get the selected items on pressing a submit button on the form ?
I'm not sure if I'm following what you're trying to achieve, do you want a visual change when you check the checkbox? If so the best option would be using jQuery and attach to the onchange event of the checkbox.
Then when you postback the form you can itterate through the items within the ListView and locate the checkbox, check its checked state and then do what you want:
foreach(var item in listView1.Items){
var checkbox = (CheckBox)item.FindControl("checkBox1");
if(checkbox.Checked) // do stuff
}

i used treeview control inside dropdownlist. but it will not work
You can't place anything except ListItem into DropDown control. Consider to place TreeView below the dropdown and update it on SelectedIndexChanged dropdown's event. Or use some client-side staff like this one: mcDropdown jQuery Plug-in
I have a Telerik RadComboBox with an item template. In the item template I have an ASP checkbox. I have a client onclick handler for the checkbox and in that I want to get the telerik RadComboBoxItem object and from that get the RadComboBox object. I can get the DOM elements by of the item by from checkbox.parentNode.parentNode. Telerik has a method to get the DOM element from a RadComboBoxItem, but how do I get the item from the DOM element?
Thanks,
Brian
Even with templates, you can set the text and value fields to bind I believe. With that said, if you store the text in the checkbox, you should be able to get the master RadComboBox and find it with findItemByText method... (mentioned here: http://www.telerik.com/help/aspnet/combobox/comboclsideobject.html).
You could also look at the HTML to see if the DIV for the combo box item has a unique ID; if it does, you could get the ID and use $find(id) to return you the item too. I don't remember this if it does or not.
Some ideas, HTH
I am designing a user control in ASP.NET where in i have a Textbox and onfoucus javascript event i am showing a checkbox list below and onBlur event i am hiding the checkbox list control
Now the problem is when i focus the textbox the Checkbox is visible and when i try to go and check the items it is getting hidden as onBlur event is called.
How can i avoid this any other way for this basically like a dropdown list....
Don't hide it in the onblur event.
Imitate what a real dropdown list does: it only goes away when either [a] you click an item in the list [b] some other page element is clicked.
Try hiding the checkbox on the click event (of checkbox).
We have a Datalist in which we have some data, with every Item we have a button control. What I want to achieve is that on the button click, the data related to that particular row of Datalist is fetched whose Button control is clicked. How to accomplish this? The problem is how to attach the button control with values related in that particular row? Note that I am using ArrayList as the Datasource since I am enabling padding via pageDataSource class...
Implement the OnDataBinding event for the Button. Then in the Button set the CommandArgument to something that will identify the row you are clicking. Then implement the OnItemCommand event for the DataList. You will be able to read the CommandArgument for the Button that was clicked and then perform whatever action you need.
