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 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?
Private Sub cmbGroup_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmbGroup.SelectedIndexChanged ' Get valuemember here End Sub
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:
For Each row As ListViewItem In listIngView.Items

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.

View 3 RepliesI 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.

View 4 RepliesI 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...

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.
View 1 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.
Is there any way to get the ComboBox SelectedIndex based on SelectedValue when Datasource property is set with DisplayMember and ValueMember?
