Solution 1

Even if I do not understand the utility of this thing, try this:

C#

void ClearInputs(ControlCollection cs)
    {
        foreach (Control c in cs)
        {
            if (c is TextBox)
            {
                Session[c.ID] = ((TextBox)c).Text;
                lbl_savesubmit1.Text += Session[c.ID];
            }
        }
    }

Hi Mario, In my page there are huge number of text boxes, so i need to keep text entered in text boxes. In a single loop i need to store the data in sessions..

Mario Majčica 29-Aug-12 8:49am

The code I proposed will do the job. If you need to restore the values, you can do the opposite process. However this is not an elegant solution for solving a problems of this type.

Hello,

I also doesn't understand the scenario you want to resolve, Hope following code snippet will help you to solve your problem.

C#

void ClearInputs(ControlCollection cs)
        {
            List<String> lstSessions = new List<string>();
            foreach (Control c in cs)
            {
                if (c is TextBox)
                {
                    lstSessions.Add(((TextBox)c).Text);
                    lbl_savesubmit1.Text += ((TextBox)c).Text;
                }
            }
            Session["TxtSession"] = lstSessions;
        }

Thanks!!!!!!!

Tell me how to call this function in a submit button. I wrote this:ClearInputs(Page.Controls); //want to get all the controls in the webpage.
But its not working.

Mario Majčica 29-Aug-12 8:55am

What you are asking is to find recursively all the controls in the page. Try this
public static List<Control> GetAllControls(ControlCollection ctrls)
{
List<Control> RetCtrls = new List<Control>();

foreach (Control ctl in ctrls)
{
if (ctl is TextBox)
{
RetCtrls.Add(ctl);
}
else
{
RetCtrls.AddRange(GetAllControls(ctl.Controls));
}
}

return RetCtrls;
}

Are you using master pages? if so this code will not work.

narlakanti 30-Aug-12 0:26am

Ya am using master page...So what is the solution for this scenario.. Any help will be appriciated.

Vinod Viswanath 30-Aug-12 0:40am

See my below solution hope that will help you to iterate through content panels

Solution 3

Hi,
If you are using Master Pages you have to iterate through all the containers to reach the control. Hope this will help you.

C#

protected void Button1_Click(object sender, EventArgs e)
    {
       // if(!IsPostBack)
        ClearInputs(Page.Controls);
    }

    void ClearInputs(ControlCollection cs)
    {
       
        foreach (Control container in cs)
        {
            foreach (Control childContainer in container.Controls)
            {
                foreach (Control innerChild in childContainer.Controls)
                {
                    foreach (Control control in innerChild.Controls)
                    {
                        if (control is TextBox)
                        {
                            ((TextBox)control).Text = string.Empty;
                            Session[childContainer.ID] = ((TextBox)control).Text;
                            lbl_savesubmit1.Text += Session[childContainer.ID];
                        }
                    }
                }
            }
        }
    }

Thanks!!!

Hi, control is not going into the loop.

Vinod Viswanath 30-Aug-12 1:24am

Hi, Can you paste your code behind here?

narlakanti 30-Aug-12 1:53am

This is my code behind. My scenario is I have a tab container with 3 Levels like Level 1, Level 2, Level 3 and a button in each button. So after entering the level 1 data i will click on button, then the tab will move to the level 2 and the data entered in level 1 should be kept in sessions.Similarly for Level 2 and level 3. So finally if i click on submit button in level 3 the data in Level 1,Level 2 and Level 3 should be submitted to database.

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
tab_level1.ActiveTabIndex = 0;
txt_dob.Attributes.Add("readonly","");
txt_fd_dob1.Attributes.Add("readonly","");

}
if (Session["New"] != null)
{
lbl_savesubmit1.Text += Session["New"].ToString();
}
else
{
//Response.Redirect("")
}
}
protected void btn_save_continue_Click(object sender, EventArgs e)
{
pnl_level2.Enabled = true;
tab_level1.ActiveTabIndex = 1;

ListControlCollections();
}

private void ListControlCollections()
{
ArrayList controlList = new ArrayList();
AddControls(Form.Controls, controlList);
foreach (string str in controlList)
{
Response.Write(str + "<br/>");
}
Response.Write("Total Controls:" + controlList.Count);
}
private void AddControls(ControlCollection page, ArrayList controlList)
{
foreach (Control c in page)
{
if (c is TextBox)
{
Session["New"] += ((TextBox)c).Text;
lbl_savesubmit1.Text += Session["New"].ToString();
controlList.Add(c.ID);
}
if (c.HasControls())
{
AddControls(c.Controls, controlList);
}
}
}
protected void btn_save_continue1_Click(object sender, EventArgs e)
{
pnl_level3.Enabled = true;
tab_level1.ActiveTabIndex = 2;
}

Sorry i was asking you the html code behind, not the code. i tried your code with my webpage it works fine for me.
