Save File Dialog Box (Auto populating File Name)

Question

I am having a hard time finding solution to this problem I am trying to save a PDF file using iText Sharp in Windows Form Application however everytime I try to save the file I have to feed the file name manually What i want to do is that when Save As Dialog Box appears the file name should auto populate by concatenating values from 3 different textboxes as a file name. For eg. File Name: CID1CON4INV125 ( CID stands for Customer ID which is 1  CON stands for Contract ID which is 4  INV stands for Invoice ID which is 125 and is unique ) Above example may be very tedious to remember if i have to chose a file name everytime is there a way that i can automate this process by taking the file name from txtCustomerID.Text and txtContractID.Text and txtInvoiceID.Text and prepare a file name to be saved as PDF. Thanks.

It looks to me like you'd already figured that one out in your last post: string folderPath = C:\PDFs\; if (!Directory.Exists(folderPath)) { Directory.CreateDirectory(folderPath); } string filePath = string.Format({0}CID{1}CON{2}INV{3}.pdf folderPath txtCustomerID.Text txtContractID.Text txtInvoiceNo.Text); using (FileStream stream = new FileStream(filePath FileMode.Create)) { // write content to file }

It does work however if i have to save the file with a different name or place it somewhere on the disk will increase the work so was wondering if there is any possibility to save it by pulling the file name from text box values.

It's working OK for me except that the file extension .pdf is suppressed in the SaveFileDialog itself. If you already have a definite file name do you need to use the SaveFileDialog at all? Couldn't you just save it directly to disk using that name? EDIT: In your last post you're missing the line: dlg.FileName = fileName; before you call ShowDialog()

//string folderPath = C:\PDFs\; //if (!Directory.Exists(folderPath)) //{ // Directory.CreateDirectory(folderPath); //} //using (FileStream stream = new FileStream(folderPath + CON + txtContractID.Text + CID + txtCustomerID.Text + INV + txtInvoiceNo.Text + .pdf FileMode.Create)) SaveFileDialog dlg = new SaveFileDialog(); dlg.Filter = PDF|*.pdf; dlg.FilterIndex = 0; string fileName = string.Format(CID{0}CON{1}INV{2}.pdf txtCustomerID.Text txtContractID.Text txtInvoiceNo.Text); if (dlg.ShowDialog() == DialogResult.OK) { fileName = dlg.FileName; File.WriteAllText(Name test); The commented codes actually puts a file in the folder by taking the values from the textbox however solution you proposed does not work.

Try: saveFileDialog.FileName = string.Format(CID{0}CON{1}INV{2}.pdf txtCustomerID.Text txtContractID.Text txtInvoiceID.Text);
