Displaying Arrow Images dynamically....

You can do that in client-side.. using Javascript.. if this is what you want, let me know so I give you an example...

is this causing a postback which shows the details ?

If so its very easy on either side (javascript or codebehind)

Hi,
  caner_elci, Iam ready to use some javascript, but Iam writing displaying those employeenames using linkbuttons in codebehind, and I know I can append JavaScript in Codebehind, can you please provide me some javascript code which will do that for me, if possible please provide me the javascript code so that I can easily embed that into codebehind..

 gregoryyoung, Iam really not sure which one your asking whether it is causing postback r not??, but I'll explain you wht exactly going on (sorry for being so dumb)... Iam writing a database query which will get me all the employee names and looping through the Reader and creating a linkbutton and the tex of the linkbutton is the employee name and attaching all the link buttons to one eventhandler function, before attaching this link button to a table cell (to place the linkbutton at appropriate place on the page) Iam also attaching a black arrow Image to the table cell... and all this is done in PageLoad() event of the page. this is wat happening in the page, I want a mechanism to check which linkbutton is clicked and accordingly I want to place a red arrow instead of black arrow...


Thank You,
Steve

Hi Steve,

Of course, I can write a sample code for you.. But I need to see your code.. can you please paste some code from your aspx file? Especially, the parts those you create buttons.. So I can write a few Javascript functions to enable/disable them...

Caner

public void Page_Load()
{
  //after opening the database connection and getting the data into the Reader Object
 // this is how my code looks like....
  while(Reader.Read())
  {
   //create a link button for each employee
    LinkButton lnkEmp = new LinkButton();
   // set linkbutton properties
    lnkEmp.ID = Reader["EmpID"].ToString();
    lnkEmp.Text = Reader["EmpName"].ToString() + "<br>";
  //set linkbutton clickevent handler
    lnkEmp.Click += new EventHandler(this.ProcessClick);

   // create a row and cell to attach Image and linkbutton to the page
    HtmlTableRow tblRowEmp = new HtmlTableRow();
    HtmlTableCell tblCellEmp = new HtmlTableCell();
    HtmlTableCell tblCellBarrow = new HtmlTableCell();
   
   //create a HtmlImage and add source as BlackArrow Image and set some prop
    HtmlImage imgBarrow = new HtmlImage();
    HtmlTableCell tblCellBarrow = new HtmlTableCell();
    imgBarrow.Src = "/images/Barrow.gif";
    tblCellEmp.Align = "left";

   //attach link button and image to appropriate cells
    tblCellBarrow.Controls.Add(imgBarrow);
    tblCellEmp.Controls.Add(lnkEmp);
   //attach cells to the row...
    tblRowEmp.Cells.Add(tblCellBarrow);
    tblRowEmp.Cells.Add(tblCellEmp);
  //above row is already attached to a table....
  }
}

that is what happening in my Page_Load() event of the page, Please let me know if you dont understand anything...

Thank You,
Steve

This is fine, but I need to know when and where you are going to disable buttons?

when the user clicks on the link button, instead of BlackArrow Image I want to put  Red Arrow Image before the linkbutton (the code I wrote to put black arrow image I want to replace with it similar code to put red arrow image)..

Steve

I am sorry for the late reply, But your code is not working, can you please look into where I am doing wrong... here is what I am doing in my case with your example...

public void Page_Load()
{
  //after opening the database connection and getting the data into the Reader Object
 // this is how my code looks like....
  while(Reader.Read())
  {
   //create a link button for each employee
    LinkButton lnkEmp = new LinkButton();
   // set linkbutton properties
    lnkEmp.ID = Reader["EmpID"].ToString();
    lnkEmp.Text = Reader["EmpName"].ToString() + "<br>";
  //set linkbutton clickevent handler
    lnkEmp.Click += new EventHandler(this.ProcessClick);

   // create a row and cell to attach Image and linkbutton to the page
    HtmlTableRow tblRowEmp = new HtmlTableRow();
    HtmlTableCell tblCellEmp = new HtmlTableCell();
    HtmlTableCell tblCellBarrow = new HtmlTableCell();
   
   //create a HtmlImage and add source as BlackArrow Image and set some prop
    HtmlImage imgBarrow = new HtmlImage();
    HtmlTableCell tblCellBarrow = new HtmlTableCell();
    imgBarrow.Src = "/images/Barrow.gif";
   
// code added..
    imgBarrow.ID = "arrow" + counter // Iam incrementing the counter every call..
    lnkEmp.Attributes.Add("onClick",imgBarrow.ID+".src='/images/Rarrow.gif';");
    lnkEmp.Attributes.Add("href","#");

   //attach link button and image to appropriate cells
    tblCellBarrow.Controls.Add(imgBarrow);
    tblCellEmp.Controls.Add(lnkEmp);
   //attach cells to the row...
    tblRowEmp.Cells.Add(tblCellBarrow);
    tblRowEmp.Cells.Add(tblCellEmp);
  //above row is already attached to a table....
  }
}

in the above code "//code added part "is the one I am changing rest everything I am keeping the same... can you please help me out what's wrong with one Iam doing...

First of all, I have a question.. what are you going to do when users clicks on your lnkEmp? I ask this, because I see that you are adding an event handler to that button, which causes postback (refreshing page and running your server-side code - this.ProcessClick)... So next time the page is loaded, your client-side changes, such as changing image source, will not be seen..

Actually in my case I definitely need to have the post back and the link buttons has to be created dynamically in PageLoad event anyways... I have got the way around in c# without using javascript I have got the solution... but I dont know for some reason your way is not working, I tried to do it in normal way not using my code just sample example, still it was not working... I guess Im doing some thing very wrong...

But still I really appreciate ur help and ofcourse Im accepting ur answer....
I have another Question, I have posted that in ASP.NET section, If you could I would really appreciate your looking at that question.... ..

Thank You,
Steve...

Thank you, I'll check it out..
