Event handling of dyanmic controls

[Hellogeetu]

Hi All,

I am creating dynamic controls but not on page_load event but on one of the button click event.

I m able to get the controls value by using request.form but i m unable to handle the event created of dyanamically created button.

Please help me, if any one having solution for my problem.
I know that i can raise that event if i recreate these controls on page load but my reqirements doesn't allow me to do so.

My code for dynamially creating controls r as follows:

protected void generateAttributesForType()
{
oCatMgrBl.intListingTypeId =Convert.ToInt32(txtListingTypeId.Text.ToString());
ht=oCatMgrBl.return_AttributesForListingType();
 
if (ht["Status"].ToString() == "S")
{
if (((DataSet)ht["AttDataSet"]).Tables[0].Rows.Count > 0)
{
DataView dv= new DataView(((DataSet)ht["AttDataSet"]).Tables[1], "true", "", DataViewRowState.CurrentRows);
foreach (DataRow dr in ((DataSet)ht["AttDataSet"]).Tables[0].Rows)
{
 
HtmlTableRow htr = new HtmlTableRow();
HtmlTableCell htc11 = new HtmlTableCell();
HtmlTableCell htc12 = new HtmlTableCell();
HtmlTableCell htc13 = new HtmlTableCell();
HtmlTableCell htc14 = new HtmlTableCell();
HtmlTableCell htc15 = new HtmlTableCell();
HtmlTableCell htc16 = new HtmlTableCell();
HtmlTableCell htc17 = new HtmlTableCell();
htc11.VAlign = "top";
htc12.VAlign = "top";
htc13.VAlign = "top";
htc14.VAlign = "top";
htc15.VAlign = "top";
htc16.VAlign = "top";
htc17.VAlign = "top";
htr.ID = dr["intAttributeID"].ToString();
 
htc11.Controls.Add(new LiteralControl(dr["vchAttributeName"].ToString()+":"));
htc11.Align = "right";
htc11.Attributes.Add("width", "29%");
htr.Cells.Add(htc11);
 
// To generate the control either textbox, dropdownlist
if (dr["enumControlType"].ToString().Trim() == "T")
{
TextBox txt = new TextBox();
txt.ID = "txt"+ dr["intAttributeID"].ToString();
txt.CssClass = "input";
htc12.Controls.Add(txt);
htc12.Align = "left";
htc12.Attributes.Add("width", "45%");
htr.Cells.Add(htc12);
}
 
 
 
//for adding up buttons
ImageButton imgUp = new ImageButton();
imgUp.ID = "imgUp" + dr["intAttributeID"].ToString();
imgUp.ImageUrl = "images/up.gif";
imgUp.CommandArgument = dr["intTypeSequencingId"].ToString() + "," + dr["intAttributeID"].ToString();
imgUp.Click += new ImageClickEventHandler(imgUp_Click);
htc16.Controls.Add(imgUp);
htc16.Align = "left";
if (dr["intTypeSequencingId"].ToString() == ((DataSet)ht["AttDataSet"]).Tables[0].Compute("min(intTypeSequencingId)","").ToString())
{
imgUp.Attributes.Add("onclick", "javascript:alert('You are at top level');return false;");
}
htr.Cells.Add(htc16);
 
//for adding Down buttons
ImageButton imgDown = new ImageButton();
imgDown.ID = "imgDown" + dr["intAttributeID"].ToString();
imgDown.ImageUrl = "images/down.gif";
imgDown.CommandArgument = dr["intTypeSequencingId"].ToString() + "," + dr["intAttributeID"].ToString();
imgDown.Click += new ImageClickEventHandler(imgDown_Click);
Page.Controls.Add(imgDown);
htc17.Controls.Add(imgDown);
htc17.Align = "left";
if (dr["intTypeSequencingId"].ToString() == ((DataSet)ht["AttDataSet"]).Tables[0].Compute("max(intTypeSequencingId)", "").ToString())
{
imgDown.Attributes.Add("onclick", "javascript:alert('You are at bottom level');return false;");
}
htr.Cells.Add(htc17);
Session["Table"] = 1;
tblAttributes.Rows.Add(htr);
}
 
}
 
}
 
}
 
void imgDown_Click(object sender, ImageClickEventArgs e)
{
ImageButton move = (ImageButton)sender;
string[] abc = move.CommandArgument.ToString().Split(',');
oCatMgrBl.intAttributeId = Convert.ToInt32(abc[1].ToString());
oCatMgrBl.SequenceId = Convert.ToInt32(abc[0].ToString());
oCatMgrBl.whereToMove = "D";
ht=oCatMgrBl.UpdateListingSequencing();
MessageControl1.showMessage(ht);
//generateAttributesForType();
}

Thanks.......

What exactly are your requirements? I don't believe that you can do this in one function.

[Hellogeetu]

I m creating forms field from the table.
According to the category i selected the form fields also changes. So i couldn't create controls on page load i have to create it on dropdown selection changed event. Also i have to change the sequencing of the form attributes.
