HOW CAN I ACCESS THE BUTTON CONTROL FROM ASPX IN ASPX.CS?
-
Hi Everyone, I get the error:The name 'postComment' does not exist in the current context groups.aspx.cs doesn't see what's in the groups.aspx. I can't use the option of putting the code inside the aspx together. I would like to know how to access the textbox from the aspx.cs page I have two pages: groups.aspx groups.aspx.cs I have created a button in the groups.aspx as follows: Now I want to access it from the groups.aspx.cs to insert the contents of what was entered in the text box to the database as follows: protected void postBtn_Click(object sender, EventArgs e) { SqlDataSource PostDS = new SqlDataSource(); PostDS.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString(); PostDS.InsertCommandType = SqlDataSourceCommandType.Text; PostDS.InsertCommand = "INSERT INTO GroupChalkboard (Text, GroupID, UserID, CreatedDate) VALUES (@Text, @GroupID, @UserID, @CreatedDate)"; PostDS.InsertParameters.Add("Text", postComment.Text); PostDS.InsertParameters.Add("GroupID", pid.ToString()); PostDS.InsertParameters.Add("UserID", User.Identity.Name); PostDS.InsertParameters.Add("CreatedDate", DateTime.Now.ToString()); PostDS.Insert(); } Thank you.

Actually, those are not two pages. This is just one page and its code-behind file. 1. In Groups.aspx, the code file should be set to groups.aspx.cs.
CodeFile="groups.aspx.cs"2. Check whether that textbox has runat="Server" or not.Thanks and Regards, Michael Sync ( Blog: http://michaelsync.net)

The thing is that I have created the button and the textbox inside the Datalist, and because of that I can't access it directly. I don't know how to access it from the DataList. Here is the code: I removed the open tags because it's not showing the code otherwise: asp:datalist id="DataList1" runat="server" datasourceid="ChalkDL"> itemtemplate> asp:textbox id="postComment" runat="server"> asp:button runat="server" onclick="postBtn_Click" id="postBtn" text="Post!" /> /itemtemplate> /asp:datalist>

There are some events called Item_DataBound or Row_Created event. In those events, you can find the control.. For example:
TextBox txt = e.FindControl("controlname");Thanks and Regards, Michael Sync ( Blog: http://michaelsync.net)

I just find a possible solution but for some reason I get an error: System.Web.UI.WebControls.TextBox PostText = (System.Web.UI.WebControls.TextBox)DataList1.FindControl("postComment"); The name 'DataList1' does not exist in the current context The data list was declared as: asp:datalist id="DataList1" runat="server" datasourceid="ChalkDL"> And what's weird is that I can find DataList1 as an option in the properites and methods drop list when I start typing it. What can be the reason for it?

Here is the code: protected void postBtn_Click(object sender, EventArgs e) { SqlDataSource PostDS = new SqlDataSource(); System.Web.UI.WebControls.TextBox PostText = (System.Web.UI.WebControls.TextBox)DataList1.FindControl("postComment"); PostDS.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString(); PostDS.InsertCommandType = SqlDataSourceCommandType.Text; PostDS.InsertCommand = "INSERT INTO GroupChalkboard (Text, GroupID, UserID, CreatedDate) VALUES (@Text, @GroupID, @UserID, @CreatedDate)"; PostDS.InsertParameters.Add("Text", PostText.Text); PostDS.InsertParameters.Add("GroupID", pid.ToString()); PostDS.InsertParameters.Add("UserID", Session["UserID"].ToString()); PostDS.InsertParameters.Add("CreatedDate", DateTime.Now.ToString()); PostDS.Insert(); }
