custom control client values gone with postbackHi,
I'm trying to make my own web custom control. I've made a control with 2 textboxes and 1 dropdownlist. But when I enter values in them and get a postback the values are gone. How can I hold the values typed in by the client?? (for processing on the server but also to display them back) tia could this be an enableviewstate=false issue?

it is populated in the page_load, the selected item get's lost. So i obtain the value from the request.form stuff.

http://www.dotnetnewsgroups.com/newsgroupthread.asp?ID=205651&NewsgroupI D=9 Isn't there a solution? Thanks, Gellert Problem Solved:
Hello all, I could solved the Problem with an article "Extending a TextBox Control in ASP.NET" by Anthony Hart. Here is the important part is to use the ViewState: get { this.EnsureChildControls(); //This was the old code: return selectedvalue; return ((string)ViewState["something"]); } set { this.EnsureChildControls(); //This was the old code: selectedvalue = value.ToString(); This was the old code ViewState["something"] = value; Now it is working. here is the Link to the article: http://www.eggheadcafe.com/articles/pfc/extendservercontrol.asp Look at the "ViewState" section ! Gellert No...no...no this does not solve my problem!!!
I have 3 controls (2 textboxes and 1 dropdownlist) The values entered by the client are lost by a postback!! In the get I dont have any references to the controls anymore (this.Controls.Count = 0) I can not get the values of the controls... string EnteredData { get { //This will NOT work cos all the properties are empty after a postback!: return TextBox1.text + TextBox2.text + dropdownlist1.selectedindex.tostring(); //This doesnt work either because the controls.Count =0!!!: return ((TextBox)Controls[0]).text + ((TextBox)Controls[1]).text; } } I am not setting the values (the client is) so I dont have a set.....

And they do work. i obtain the text entered during a button_click event. As mentioned, i'm obtaining it using request, because the controls where empty, as you mentioned. Dim s As String = Request.Form(Me.uc1.Text1_GetUniqueID).ToUpper.Trim Note that Text1_GetUniqueID is only a property obtaining the unique ID from the textbox. Nothing serious.

Autopostback is enabled for each control? Can you post your whole code, or send it to me: radi***@gmx.at I will have a look. Gellert Hi Gellert,
Thanks for your time. I've mailed you the code.
