Problem with event not raised on a LinkButton in a Custom Control

Question

User-593237760 posted

Hi everybody, i want you to help me to resolve this problem of event, i tested a lot of things and i've started to abandon...

 

So, this is the context : I created a Control inherited from Table and, in this control i've a control named ColumnTable (inherited from TableCell). This last control will serve to make sorting operations on my Table (which is filled with a list pre-binded).

This ColumnTable control contains a LinkButton. With a click on this LinkButton, i want to raise an event that will call an other event.

 

I tried to do that:

 

 /// <summary>
        /// Name of the column
        /// </summary>
        public string Name { get; set; }

/// <summary>
        /// Init of the control
        /// </summary>
        /// <param name="e"></param>
        protected override void OnInit(EventArgs e)
        {

           

            this.ID = string.Format("Column{0}",this.Name.Trim().Replace(" ",""));

            this.linkButton.ID = string.Format("LinkButton{0}", this.Name.Trim().Replace(" ", ""));
            this.linkButton.Text = this.Name;

            this.linkButton.Text = this.Name;
            this.Controls.Add(this.linkButton);

            

            this.linkButton.CssClass = "label";
 
            

            base.OnInit(e);

            this.EnsureChildControls();

            this.linkButton.Click += new EventHandler(linkButton_Click);
        }

void linkButton_Click(object sender, EventArgs e)
        {

            //Event created

            this.OnHyperLinkClick(e);
        }

 


And also that :

 

/// <summary>
        /// Creation of the control
        /// </summary>
        /// <returns></returns>
        protected Panel CreateControl()
        {
            Panel panel = new Panel();

            

            this.linkButton.Text = this.Name;
            panel.Controls.Add(this.linkButton);

            this.linkButton.CssClass = "label";

            return panel;
        }

        /// <summary>
        /// Control Panel added to ColumnTable
        /// </summary>
        protected override void CreateChildControls()
        {
            this.Controls.Add(this.CreateControl());

            base.CreateChildControls();
        }

 /// <summary>
        /// Init of the control
        /// </summary>
        /// <param name="e"></param>
        protected override void OnInit(EventArgs e)
        {

            

            this.ID = string.Format("Column{0}",this.Name.Trim().Replace(" ",""));

            this.linkButton.ID = string.Format("LinkButton{0}", this.Name.Trim().Replace(" ", ""));
            

            base.OnInit(e);

            this.EnsureChildControls();

            this.linkButton.Click += new EventHandler(linkButton_Click);
        }

        void linkButton_Click(object sender, EventArgs e)
        {

                        //Event created 

            this.OnHyperLinkClick(e);
        }

  

I never pass through the event Click of my LinkButton, i don't understand why... My controls are added, it's like if it doesn't recognize the LinkButton .

 

If you have answers, i'll be happy, thanks :) .
