Select The Correct Valuemember And Displaymember After Changes?
Mar 14, 2009
I 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 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

using 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
[Code]....

My question: i have a combobox which i would like to populate with data from a database. The table looks like this: pkIntCompany (the pk) & chrCompanyName You see nothing special.
I would like all the records in a combobox. When a user selects one of the value, i would like to show the pk and the combobox in a textbox (seperate). Is there someone who has some example code?

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?

I have binded a datatable to a combobox, using DataSource, DisplayMember and ValueMember properties. Now I try to set the combobox to a preset value using comboBox.SelectedValue = value. Nothing happens however.

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...

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 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 have some code in a VB module. When I run this with the SQL statement having hard coded values in the where statement it works. I am now trying to add Parameters to the module so that the Form can except an Input from a user, but I am getting the message: Input string was not in a correct format.
Here is the section of code:
objCon.Open()
objCmd.Connection = objCon
objCmd.CommandType = CommandType.Text
objCmd.CommandText = sSQL
[Code] .....
Like I said, if I substitute the Parameters for fixed values it all works.

Note, I screwed up and asked how to get DisplayMember text, I meant to put ValueMember...
I have a combo box I'm populating from a datatable. It has two columns, one for display and one for value. I can find the index of the associated item in the combobox list using the FindString method, but how do I retrieve the value member string from the return of this?

Combobox with bound rowsource, but I want to change the displaymember to a string returned by a procedure. In Access/VBA I would have a little function to build the string, then simply code the recordsource of the cbo as:
"SELECT ClientIDS, fnGetName([ClientIDS]) AS ClientName FROM tblPerson ORDER BY fnGetName([ClientIDS])".
Pretty straightforward, but I've messed around with this for hours in VS2005/VB to no avail.SELECT ClientIDS, fnGetName
