I want to give tooltip to dropdownlist box as like...
When I just click on the DropDownListBox then it populates the list of items.
When I move on the on of item then color of that item changes to blue I want to assign
the tooltip for this particular item.
Because my text of listitem is too large which is greater than width of listbox.
Is there any event to capture the moved listitem?
Please tell me how this can be possible.
To do this, you can loop through the dropdown list items and add a title attribute to each ListItem (if you are using asp.net webforms):
For Each listItem As ListItem In DropDownList.Items
listItem.Attributes.Add("title", listItem.Text)

I have a list of items. First I select an item from list then save it in local db. Now I want that when user open app next time. The save item should be default selected in the list. But no item is selecting default when user comes next time.
How is it possible in xamarin.forms to select an item default selected in listview?
You can set the Listview Selected Item in your code behind.
Assuming you have Binded your ItemsSource, you just need to get the object you want to set as selected and do this:
ListviewItems.SelectedItem = YourCollection[YourIndex];
I follow these to create checkable combobox
ComboBox of CheckBoxes?
http://programmingexamples.net/wiki/Qt/ModelView/ComboBoxOfCheckBoxes
However when I do a this->Model->clear() then add items, the combobox text (the text combobox displays before user clicking anything) goes blank. The items will still show and are checkable when click on the combobox. I suspect the clear() remove the header and causes this, however I try setHorizontalHeaderLabels etc but I still can't set the combobox text. What am I missing?
Try setting the ComboBox's selected index after you add items. Like:
ui->combobox->setCurrentIndex(0);
Because it could be that after you clear the ComboBox, its display index may have gone to -1 and stayed there even if you add items.
I am using GridView on my page, which retrieves data from SQL database.
The first column is named OK and has a Checkbox in each row.
I want to select each check box with the help of keyboard instead of mouse.
The shortcut for toggling a checkbox is the spacebar, so as long as you have the checkbox highlighted, you can use that to check each box.
Next, check out some articles on adding GridView keyboard navigation:

I have one flex datagrid which contains number of rows and column. I want to make selected row editable by clicking on edit button. Is it possible? I have try many samples but on that either entire datagrid is editable or particular row's single column is editable. Is there any way to make selected row editable by clicking on edit button?
You can get the selected row with the grid.selectedIndex property. One thought to you problem:
Add an "editable" property to you items in the datagrid which is false by default
When clicking on the button, set grid.selectedItem.editable = true;
Change the grid's item renderer to a new one, which displays TextInput fields if an item is editable or just plain Label if it's not
You can change the item renderer at runtime like this:
grid.itemRenderer = new ClassFactory(com.myapp.renderers.MyGridItemRenderer);
How to remove a textbox and put the dropdown box in asp.net
And the value that is used before in textbox, now it should take from dropdown box
You can use select tag for this. And can get the selected value in C# using the following code
Suppose cmb is the id of your dropdown box, then
cmb.Items[ cmb.SelectedIndex ].Value
can fetch the value selected in your drop down box and
cmb.Items[ cmb.SelectedIndex ].Text
can fetch the text selected
easiest way is to use jquery and jquery.jeditable plugin with it.
