I need to create a user control which can be used in my all projects. I have created a user control with a TextBox Control and a ListBox Control. My goal is that as soon as any character is pressed in the textbox, Listbox's item which starts from that character should be selected. I have done all the coding needed for the functionality but my problem is that when I add this usercontrol to my form, I should be able to change the DataSource, displaymember and valuemember properties at designtime. But I cannot see these properties when I add the control on the form.

I have DataGridViewCombobox column in my winform. i have bound that comboboxcolumn from database by setting its DataSource, DisplayMember and ValueMember property.
i want to set DisplayMember based on ValueMember. just like we do in normal combobox like
Combobox.SelectedValue = "12"
I tried following
gridAttendance.Rows[0].cells[2].value = dsAttendance.Tables[0].Rows[0]["Id"].ToString();
but it doesn't work...
"It throws an error saying datagridviewcomboboxcell value is not value"
i also tried handling DataError event of GridView, but still it doesn't work

I've got an Access 2007 table with names of people and the unique ID # of their sponsoring agencies. There is a second table in the accdb with the sponsoring agencies and their unique ID #. How do I display the actual agency name, and not the ID #, in a combobox?
What I want to see is this:
John Doe ABC Corporation (John Doe in textbox, ABC in combo)
The results I'm getting is this however:
John Doe 10
I'm using the code below to display the agency and name. I know this is not the right code but don't know what other code to use.
DirectCast(e.DataRepeaterItem.Controls("cboSponsoringAgency"),
ComboBox).Text
= currItem("SponsoringAgencyID").ToString

I can create a combobox with autocomplete and it works fine. However I want to return a code value instead of the description much the same as a normal combobox where there is a displaymember and a valuemember. Is this possible?

View 4 RepliesI have an editable ComboBox with a validation on the Text property to make sure manually entered info is valid.EDIT: All I want to do is populate the .Text property with the ValueMember of a selection rather than the DisplayMember I also have the .Items populated with valid entries having the DisplayMember and ValueMember set.My DisplayMember is a caption along with the data, and the ValueMember is the data itself.So Items might be:
(DisplayMember, ValueMember)
"Foo - 1ab2" , "1ab2"
"Bar - 3cd4" , "3cd4"
I had a validation on the text which can also validate manual user input like "5ef6" The problem I'm having is that if the user selects an item from the combobox it populates the text field with the DisplayMember property (ex: "Foo - 1ab2") which will fail validation.I have tried to manually set the .Text property with the SelectedValue or the SelectedItem.Value on each of the three relevant combobox events to no avail.I would like that the .Text of the ComboBox get populated with the .ValueMember of the item when selected rather than the .DisplayMember
EDIT: I cannot validate by trying to extrapolate the value from the caption. I send the Text off to a service to be validated.
void FillMyCombo
{
KeyValuePair<string, string> listValue1 = new KeyValuePair<string, string>("Foo - 1ab2" , "1ab2")
KeyValuePair<string, string> listValue2 = new KeyValuePair<string, string>("Bar - 3cd4" , "3cd4")
[code].....
The user can manually enter something like "5ef6" which will pass validation.But when they select an item from the list, rather than manually entering it, the .Text property gets filled with the caption and not the value ... so it will contain "Foo - 1ab2" and that will fail validation. I cannot change the validation method to "infer" the value from the caption. I have no control over that service. All I'm after is the displayed value EDIT: Say a user selects "Foo - 1ab2" from the dropdown list, I want the text in the box to say "1ab2" EDIT: I have also tried to set the .Text property in code but I can't seem to make it work in any of the ComboBox events. how to programmaticly set the .Text property (and make it commit!) on a selection event they will also answer this question.
I am trying to get the valuemember of my combobox but it just won't work. I have tried a lot of things (won't post them all here) can somebody just show me how to do this?

Is it possible to BOTH set a comboboxes datasource AND databind the selected value?Ihave 2 comboboxes on a form that I want to populate with data from 1 table,ut I want the actual selected values on each of the comboboxes to come from separate columns n another datasource Right now if one combobox changes, so does the other if that makes sense.
Here's a sample of code:
'Bind DataSource
With cboYields

I am using a bound combobox control in a vb.net application. How do I set the combo box to an item if I know the value of the ValueMember, but I don't know the DisplayMember. I can use the FindExactString method if I know the DisplayMember, but not if I only know the ValueMember.In explanation, the value member is an employee Number, the display member is the Name. I get the employee number from a detail item in another table and now I want to set the combobox to display the Name that goes with that detail item.
Can someone post some vb code to show how to do this.
I've got a ComboBox with an ItemsSource which I've bound to a List(Of String).What I'd like to do is have the XAML update a String property when the SelectedValue of the ComboBox changes. I've seen a whole bunch of examples for TextBoxes which use
Text="{Binding Path=MyString}"sort of stuff, but I don't really think that'll be the way to go if, in future, I need to change the ItemsSource to a List(Of ObscureObject)...
i have a form contains DataGridView and one of its components is a ComboBox, the problem is i wanna save the ValueMember instead of the DisplayMember in the database.
View 1 RepliesI have a database that is connected with my form. There is a combobox on top of the form and with that I can select the category I want.
Now when I search or I do something else it selects records that aren't from the category I selected, so this category should change when I do such things. Nothing happens when I do something. It should select the right category that belong to the record that is selected now.

I have a couple of combo boxes, one that I have hand coded the query to load and another that uses the databinding feature. My problem is (well one of them!) that when the form loads, it displays the data stored in the table (ValueMember) and not the display member, the display members are shown in drop down once selected. Basically, I have a table that feeds the combo box with two columns both strings "Code" and "Reason" I want to display the reason when the form loads, not the code...

Is this possible? I programatically change the selected index when a certain event is fired using this code:
DropDownList.SelectedIndex = DropDownList.SelectedIndex + 1
Now I want to update a corresponding textbox with the text that is in the new SelectedIndex of the DropDownList via postback.What's the easiest way to do this?I know how I can do this in javascript.... I was just wondering if i could do this in the VB code behind.

The below function works great. I call this function from a form to load a ComboBox control on my form. It assigns the "DisplayMember" property a field from the SQL statement as well as the "ValueMember" property.
My problem occurs when, in my form I get the error message (as seen in the screenshot) from the below

I have a function that changes the text in the DisplayMember of a ListBox by first changing the DataTable DataSource and then reloading the datasource.Trouble is, editing any value under the first item causes the DisplayMember values to 'vanish' from sight - they are still there as you can click on them, they just can't be viewed!

box withing a modal form. The combobox shows a list of ingredients where the displaymember is the IngredientName and the valuemember is the IngredientID, and a user would select an ingredient in the combobox and the returning value would be the ID for that ingredient. My issue is that within this same datagridview, i'd like to prepopulate it with items already existing in the database. However i'd like to set the display value in the combobox using the id value from the database. So if "Pasta" was the ingredient name and 101 was the ID, i'd set the value as 101 and it display Pasta in the combobox.
Here's what i have so far:
