Here[^] you can find some articles which will solve the problem.

The problem is the event handler never triggers.

Check this out.

public partial class Default3 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
ButtonArray();
}

protected void ButtonArray()
{
    try
    {
        for (int i = 0; i < 14; i++)
        {
            Button new\_button = new Button();
            new\_button.ID = "btn" + Convert.ToString(i);
            new\_button.Text = "Button" + Convert.ToString(i);
            //new\_button.Click += new EventHandler(btn\_Click);
            new\_button.Click += new EventHandler(new\_button\_Click);
            panelLineA.Controls.Add(new\_button);

        }

    }
    catch (Exception ex)
    {
        lblStatus.Text += ex.Message.ToString();
    }
}

void new\_button\_Click(object sender, EventArgs e)
{
    int btnIndex = Convert.ToInt32(((Button)sender).ID.Substring(3, 1));
    lblStatus.Text = "Button " + btnIndex + " was pushed." + ((Button)sender).ID;
}

}

You can use Ajax. Use AjaxControlToolKit[^], where in you can place server side controls in UpdatePanel, and write serverside code. Thus you can avoid postbacks. I hope this helps you. Cheers, Sudhanva

My application has a online test module, where i generate controls at runtime. As shown in the code block below. I am inserting them in a datatable (one span tag in one row) I want to bind it to a control (say gridview) and provide paging. How can i do this? If i bind the datatable to the gridview i am able to see the html tags only but not the controls. I am :confused:

<span id="lblQuestion01" class="optQuizup"><br>1) CHSC Question1 (Marks 2)<br><br></span>
<span class="optQuizup"><input id="chkOption00" type="checkbox" name="chkOption00" onclick="uncheckOthers(chkOption00,0,4);" /><label for="chkOption00">vxcv<br></label></span>
<span class="optQuizup"><input id="chkOption01" type="checkbox" name="chkOption01" onclick="uncheckOthers(chkOption01,0,4);" /><label for="chkOption01">cxvcb<br></label></span>
<span class="optQuizup"><input id="chkOption02" type="checkbox" name="chkOption02" onclick="uncheckOthers(chkOption02,0,4);" /><label for="chkOption02">ghfgh<br></label></span>
<span class="optQuizup"><input id="chkOption03" type="checkbox" name="chkOption03" onclick="uncheckOthers(chkOption03,0,4);" /><label for="chkOption03">fbvcb<br></label></span>
<span id="lblQuestion11" class="optQuizup"><br>2) CHSC Question2 (Marks 2)<br><br></span>
<span class="optQuizup"><input id="chkOption10" type="checkbox" name="chkOption10" onclick="uncheckOthers(chkOption10,1,4);" /><label for="chkOption10">asdkf<br></label></span>
<span class="optQuizup"><input id="chkOption11" type="checkbox" name="chkOption11" onclick="uncheckOthers(chkOption11,1,4);" /><label for="chkOption11">ugodf<br></label></span>
<span class="optQuizup"><input id="chkOption12" type="checkbox" name="chkOption12" onclick="uncheckOthers(chkOption12,1,4);" /><label for="chkOption12">dfgkls<br></label></span>
<span class="optQuizup"><input id="chkOption13" type="checkbox" name="chkOption13" onclick="uncheckOthers(chkOption13,1,4);" /><label for="chkOption13">kldfjls<br></label></span>

Thanks

    DataTable dt1 = new DataTable("student");
    dt1.Columns.Add("Name", typeof(string));
    dt1.Rows.Add("a"); dt1.Rows.Add("b"); dt1.Rows.Add("c");
    

    DataTable dt2 = new DataTable("employee");
    dt2.Columns.Add("Name", typeof(string));
    dt2.Rows.Add("x"); dt2.Rows.Add("y"); dt2.Rows.Add("z");
     

    DataTable dt3 = new DataTable("student\_employee");
    dt3.Columns.Add("StudentName", typeof(string));
    dt3.Columns.Add("EmployeeName", typeof(string));
     
  
    //further you can add an IF condition to check the max dt.row.count here
    for (int i = 0; i < dt1.Rows.Count; i++ )
    {
        for (int j = 0; j < dt2.Rows.Count; j++)
        {
            dt3.Rows.Add(dt1.Rows\[i\]\["Name"\].ToString(), dt2.Rows\[i\]\["Name"\].ToString());
            break;
        }
    }

    //bind the dt3 with gridview here

I wanna create a form that grabs data from a database and insert it in my layout

Instead create a usercontrol (which should have your forms' controls) to bind the data, and put a for loop for number of querystring items, and call the usercontrol and bind the data. That should solve your problem. Cheers, Sudhanva

So basically, if the user enters only one value, only 1 report is queried if they entered more than 1 then more than one report is generated one after another.

What do you mean report here?? Is it a crystal report? I dont see any report binding code. I would appreciate if you elaborate your requirement. Cheers, Sudhanva

You can do it using delegates. Create a delegate in the usercontrol with some return type / parameters with which you can set the visibility of the usercontrol, add an event for this delegate. Add a button with a button click event in user ctrl. Call the event in the webpage which in turn should call the user control's button click event. Try this out. Cheers, Sudhanva

Hi karan, I dont know why you want to show it like that, but you can loop through two tables, i mean having two loops one inside the other (Note: Outer for loop should be for max row count table) and add the data in to a new table. Then bind the new table to the grid. I have not implemented this, but i am sure this should work. Try. Cheers, Sudhanva.

Check the connection string. Enter valid credentials, and database name. Cheers, Sudhanva

Refer this link[^] I hope it helps you.

Hi Sam, I tried working on the sample and it is working fine. I meand the scroll bar is at the end (right end) of the panel. You can try with div tag instead of panel: <div style="overflow:auto; width:auto; height:250px; border-color:CornflowerBlue; border-width:medium; border-style:solid;"> Sudhanva.
