Data table columns become out of order after changing data source.
- by Scott Chamberlain
This is kind of a oddball problem so I will try to describe the best that I can.
I have a DataGridView that shows a list of contracts and various pieces of information about them. There are three view modes: Contract Approval, Pre-Production, and Production. Each mode has it's own set of columns that need to be displayed.
What I have been doing is I have three radio buttons one for each contract style. all of them fire their check changed on this function
private void rbContracts_CheckedChanged(object sender, EventArgs e)
{
dgvContracts.Columns.Clear();
if (((RadioButton)sender).Checked == true)
{
if (sender == rbPreProduction)
{
dgvContracts.Columns.AddRange(searchSettings.GetPreProductionColumns());
this.contractsBindingSource.DataMember = "Preproduction";
this.preproductionTableAdapter.Fill(this.searchDialogDataSet.Preproduction);
}
else if (sender == rbProduction)
{
dgvContracts.Columns.AddRange(searchSettings.GetProductionColumns());
this.contractsBindingSource.DataMember = "Production";
this.productionTableAdapter.Fill(this.searchDialogDataSet.Production);
}
else if (sender == rbContracts)
{
dgvContracts.Columns.AddRange(searchSettings.GetContractsColumns());
this.contractsBindingSource.DataMember = "Contracts";
this.contractsTableAdapter.Fill(this.searchDialogDataSet.Contracts);
}
}
}
Here is the GetxxxColumns function
public DataGridViewColumn[] GetPreProductionColumns()
{
this.dgvTxtPreAccount.Visible = DgvTxtPreAccountVisable;
this.dgvTxtPreImpromedAccNum.Visible = DgvTxtPreImpromedAccNumVisable;

The issue is when I check a button the first time, everything shows up ok. I choose another view, everything is ok. But when I click on the first view the columns are out of order (it is like they are in reverse order but it is not exactly the same). this happens only to the first page you click on, the other two are fine. You can click off and click back on as many times as you want after those initial steps, The first list you selected at the start will be out of order the other two will be correct.
Any ideas on what could be causing this?
