View 1 RepliesVS 2008 - User Control With DataSource, DisplayMember And ValueMember Property
Nov 19, 2009I 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.

ComboBox - Display DisplayMember Instead Of ValueMember
Jun 24, 2010using vb.net 2010 and WPF
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

View 4 RepliesC# - Populate ComboBox Edit Field With ValueMember But Show DisplayMember In The List?
Oct 12, 2011I 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.

When Form Loads - Combo Box Displays Valuemember Rather Than Displaymember
Apr 23, 2009I 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...
