AutoComplete TextBox in C#

Where is the Explanation and code for the following Now, we can have a combo box that completes URLs as soon as you type any character. For example, in Figure 1, I typed "c-s" and I see all the URLs starting with "c-s".

Nice...

Hello Mahesh, could you please guide what could I do to make auto suggest work matching any word in the source phrase and not just the starting characters.

Mahesh, try to answer the question posted in the below link: ---https://social.msdn.microsoft.com/Forums/vstudio/en-US/7c08a688-8671-4d94-b465-4ae8ba3cdf7b/combobox-autocompletemode-autocompletemodesuggestappend-how-to-prevent-the-user-typing-invalid?forum=vbgeneral

Very helpful Thank you...........

hey mahesh this works only for th every first value that u populate in case if u r populating in the text box. IF I want to populate the multiple values in text box using this feature,how to do this like the one we seee in the to address fileds of outlook.Here after entering semicolon then tyr to enter next value,again it suggests and appends.I want to include that feature...

How do you control the size of dropdown? I am doing application for touch screen and all my searching turns that I have to create a custom control. However, it's not as smooth as the suggestion box.

its ok .... but i want to search condition on string any where in the string. i have used combobox text changed event.... here is my code private void cmbTest_TextChanged(object sender, EventArgs e) { string item = cmbTest.Text; item = item.ToLower(); cmbTest.Items.Clear(); List<string> list = new List<string>(); List<string> listComp = new List<string>(); for (int i = 0; i < dtvender.Rows.Count; i++) { listComp.Add(dtvender.Rows[i]["FullName"].ToString()); if (dtvender.Rows[i]["FullName"].ToString().ToLower().Contains(item))// arrayOld[i].ToLower().Contains(item)) list.Add(dtvender.Rows[i]["FullName"].ToString()); } if (item != String.Empty) foreach (string str in list) cmbTest.Items.Add(str); else foreach (string str in listComp) cmbTest.Items.Add(str); cmbTest.SelectionStart = item.Length; cmbTest.DroppedDown = true; } its work fine but when we use up down arrow key then after selecting first item list goes away.... In your code if i press m then Mac Jocky,Mahesh Chand,Millan Peter comes in the list and on pressing up down key we can select any one of the three .I want to implement same process with string any where in the Combobox..... Please give me the solution...........

nice to see such a amazing article...

[WebMethod] public string[] getClients(string prefixText, int count) { if (count == 0) { count = 10; } string key = prefixText + "%"; string qry = "SELECT COUNT(id) FROM tb_123_clients WHERE client LIKE '" + key + "'"; dr = dbu.executeReader(qry); if (dr.Read()) { count = dr.GetInt32(0); } dr.Close(); string[] items = new string[count]; qry = "SELECT client FROM tb_123_clients WHERE client LIKE '" + key + "'"; dr = dbu.executeReader(qry); int i = 0; while (dr.Read()) { items.SetValue(dr["client"].ToString(), i); i++; } dr.Close(); return items; }

Hi, I have two textboxes. As I type in one of them, there should be autosuggestion in the other one. Is this possible? Thx

Hi!!! This is Megha, well i want to know is there any method via which we could change the font size of the autocomplete list. I had tried changing the font size of the textbox this changes the font size of the text box but the list beneath it that matches the Autocomplete feature is of the smaller font only.

sir, Is there a way to have the autocomplete feature in the middle of a sentence? It works for the first word, but not after that.

Tnx :)

super super super coding sir thanks lot sir

As MVP you didn't make much effort to write this article. Did you?

I can get autocomplete to work with a standalone TextBox. But with the following C# code, I never see the auto complete drop down. Also, is it possible to see the auto complete dropdown on activation of the control, rather than after User hits first key? private void loopsDataGridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e) { string[] paramStrings = { "OUT1", "OUT2" }; AutoCompleteStringCollection autoStrings = new AutoCompleteStringCollection(); autoStrings.AddRange(paramStrings); TextBox textbox = loopsDataGridView.EditingControl as TextBox; textbox.AutoCompleteCustomSource = autoStrings; textbox.AutoCompleteMode = AutoCompleteMode.SuggestAppend; textbox.AutoCompleteSource = AutoCompleteSource.CustomSource; }

I would like to know if there's any way I can display the auto-complete list as soon as the control gets focused? (onclick should work also)

very urgent hello sir i want to select Mac Jocky (combobox item) by pressing Return key

Thanks for the article. We've now used autocomplete in our application and, quite simply, the users don't reckon it's working! This is because the "restart" delay is too quick - they type a few characters, pause for thought, and type the rest - only for the autocomplete to have restarted (we use the append type). Is there any control over this delay? In our comboboxes the "key" they are trying to find (from a list of thousands) is up to 15 characters long (letters and numbers) - so they need to be able to type this in slowly! Thanks, Dr. Michael Dye.
