I have a silverlight application.I am inserting values in a list and binding that List to datagrid with an edit and delete button before every item in datagrid.
When I click on the edit button, the values present in the item should get displayed in textbox outside datagrid. Now, when I click on edit button, the values get inserted in textbox at double click of edit button(not on single click) .I am getting the value in the property in code behind in ViewModel but that value is not populated in textbox.It only populates it at second click.
Why so? I want the value to be populated at first click on edit button.
current binding of textbox text property is :
Text="{Binding Value,Mode=TwoWay}"

I have a datagridview and textboxes all bound to a bindingsource. I also have buttons for actions Create and Update. The latter works as intended: the item in the selected row updates with values from the textboxes. Here's the whole code behind the Update button:
myBindingSource.EndEdit();
myTableAdapter.Update(myDataSet.myTable);
The Create button in current implementation adds an empty row and clears all the textboxes, so the only way to add actual values is using the Update button afterwards. Here's the whole code behind the Create button:
myBindingSource.CancelEdit();
myBindingSource.AddNew();
But I want the Create button to add a row with values already entered into the textboxes, and then clear them. I tried to only use this line:
myBindingSource.AddNew();
But if I don't cancel pending changes, 1) they'll be applied to the item currently selected in datagridview, 2) an empty row will be added to datagridview.
How can I change the Create button's behavior, so that it added rows with values from the textboxes without affecting currently selected row?
I have a data grid view where on click event i have added combo box to particular columns. After selecting one of the value from combo box, i save it in db and it gets saved successfully. Now, when I load data grid view, which contains data from database, again i need those columns as combo box, so that when i click on save without changing values of combo box columns i do not get error.
What I have already tried is adding combo box on data grid view click event.
Any idea, how to make add combo box to specific columns when I bind data to data grid view?

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
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
