how to create onclick event for dynamically generated buttons - c#

this is how i was generating buttons and on click event for the buttons.but every time on button click its taking the max value rather than the button clicked
int noofquestions = 100;
int k = 1;
for (int i = 1; i <= noofquestions / 5; i++)
{
HtmlTableRow tRow = new HtmlTableRow();
//TableRow tRow = new TableRow();
myTable.Rows.Add(tRow);
for (int j = 1; j <= 5; j++)
{
HtmlTableCell tCell = new HtmlTableCell();
tRow.Cells.Add(tCell);
Button link = new Button();
//LinkButton link = new LinkButton();
link.ID = "link" + k;
link.Text = k.ToString();
tCell.Controls.Add(link);
ViewState["qno"] = k;
link.Click += new EventHandler(link_Click);
tCell.Controls.Add(link);
//link.Click += new EventHandler(this.btn_click);
k = k + 1;
}
}
void link_Click(object sender, EventArgs e)
{
}

It is up to how you read value.
I think my meaning max value you are questioning that when you read ViewState["qno"] it is max value because it is what it set to that.
In stead of that just try to read from some other property.
void link_Click(object sender, EventArgs e)
{
//If you do ViewState["qno"] it will be max value of K instead do following thing.
}
// Do following update
int noofquestions = 100;
int k = 1;
for (int i = 1; i <= noofquestions / 5; i++)
{
HtmlTableRow tRow = new HtmlTableRow();
//TableRow tRow = new TableRow();
myTable.Rows.Add(tRow);
for (int j = 1; j <= 5; j++)
{
HtmlTableCell tCell = new HtmlTableCell();
tRow.Cells.Add(tCell);
Button link = new Button();
//LinkButton link = new LinkButton();
link.ID = "link" + k;
link.Text = k.ToString();
tCell.Controls.Add(link);
ViewState[link.ID] = k;
link.Click += new EventHandler(link_Click);
tCell.Controls.Add(link);
//link.Click += new EventHandler(this.btn_click);
k = k + 1;
}
}
void link_Click(object sender, EventArgs e)
{
Button b = (sender)Button;
string value = ViewState[b.ID].ToString();
}

Dynamic textbox values to database

I am trying to insert values from dynamic textbox to database using Entity Framework in Web Forms.
On one click it make a table row with three column and every column has one textbox. Every another click is one row more.
public static int rowCnt = 0;
protected void BtnAddNewBuildItem_Click(object sender, EventArgs e)
{
// Current row count.
int rowCtr;
// Total number of cells per row (columns).
int cellCtr;
// Current cell counter
int cellCnt;
rowCnt = rowCnt + 1;
cellCnt = 3;
for (rowCtr = 1; rowCtr <= rowCnt; rowCtr++)
{
// Create new row and add it to the table.
TableRow tRow = new TableRow();
TableBuildItems.Rows.Add(tRow);
for (cellCtr = 1; cellCtr <= cellCnt; cellCtr++)
{
// Create a new cell and add it to the row.
TableCell tCell = new TableCell();
TextBox tb = new TextBox();
// Set a unique ID for each TextBox added
tb.ID = "txtBuisniesItem_Row" + rowCtr + "Cell" + cellCtr;
// Add the control to the TableCell
tCell.Controls.Add(tb);
tRow.Cells.Add(tCell);
}
}
}
Then, on another button click i tried to insert one row values to database, but allways is empty string.
using (VODOMONTEntities context = new VODOMONTEntities())
{
BuildItem bi = new BuildItem();
for (int i = 0; i < rowCnt; i++)
{
TextBox tb1 = new TextBox();
tb1.ID = "txtBuisniesItem_Row" + (i + 1).ToString() + "Cell" + 1;
bi.Name = tb1.Text; //there is a empty string allways
context.BuildItems.Add(bi);
}
context.SaveChanges();
}
So, my question is how to insert a dynamic texbox values to database, like in this case?
Thank you!

how to get cell selected from dynamically generated html table with links

This is how im creating an table an adding link button for every cell. Im stuck in getting the selected cell value from the table
int noofquestions = 60;
int k = 1;
for (int i = 1; i <= noofquestions / 5; i++)
{
HtmlTableRow tRow = new HtmlTableRow();
//TableRow tRow = new TableRow();
tblNavigation.Rows.Add(tRow);
for (int j = 1; j <= 5; j++)
{
HtmlTableCell tCell = new HtmlTableCell();
//TableCell tCell = new TableCell();
//tCell.Text = "Row " + i + ", Cell " + j;
tRow.Cells.Add(tCell);
//tCell.InnerText = k.ToString();
LinkButton link = new LinkButton();
//HyperLink link = new HyperLink();
link.Text = k.ToString();
tCell.Controls.Add(link);
k = k + 1;
}

Dynamic rows on table c#

two part question:
1:
I am using a session state refresh to hold count of the page reloads but when using a series of if statements the validation isn't working. Code at the bottom. What am I doing wrong?
2:
Using session state against postback doesn't appear to be the most efficient method of doing this, if I added another table with the same functionality, the count would affect both tables.
For example if I only wanted people to be able to add a maximum of three rows to a table, on two tables, they would only be able to add four rows in total.
What would be a better method of storing a count for separate refreshes?
Update
I have found the issue with the code not adding rows to the existing but I'm unsure of how to fix it.
Basically each iteration is deleting the existing row then adding a single row again. So there will never be more than one row.
Any ideas?

You don't need a list of if conditions, you just need to ensure the number of rows is less than your desired limit. You also should store the limit per table to avoid your count clashing if/when more tables are added.
This is how I would do it:
(note: This won't work "as-is" - I've assumed you've removed the code to assign tbl within cmdCreate_Click()and have left it as is for clarity)
namespace FormTest
{
public partial class About : Page
{
private int myFirstTableMaxRows = 3;
protected void Page_Load(object sender, System.EventArgs e)
{
tbl.BorderStyle = BorderStyle.Inset;
tbl.BorderWidth = Unit.Pixel(1);
if (!Page.IsPostBack)
{
Session["myFirstTable_count"] = "0";
}
else
{
int count = (int)Session["myFirstTable_count"];
Session["myFirstTable_count"] = ++count;
}
}
protected void cmdCreate_Click(object sender, System.EventArgs e)
{
tbl.Controls.Clear();
int cols = 4;
int currentRowCount = (int)Session["myFirstTable_count"];
if(currentRowCount <= myFirstTableMaxRows)
{
TableRow rowNew = new TableRow();
tbl.Controls.Add(rowNew);
for (int j = 0; j < cols; j++)
{
TableCell cellNew = new TableCell();
Label lblNew = new Label();
lblNew.Text = "(" + i.ToString() + "," + j.ToString() + ")<br />";
TextBox tbNew = new TextBox();
cellNew.Controls.Add(lblNew);
cellNew.Controls.Add(tbNew);
rowNew.Controls.Add(cellNew);
}
}
else
{
Response.Redirect("http://www.google.co.uk");
}
}//end cmdCreate_Click
}
Update after question edit
The existing rows will go due to this line in the code:
tbl.Controls.Clear();
The table is being cleared, then a single row is added per the logic in the cmdCreate_Click() method.

Dynamically create textboxes,Checkboxes and Lbael for them? [duplicate]

I was trying to create a table dynamically and put textboxes in it. Here in the following code, i was trying to create a textbox with a distinct name for each k. But only the last value of k is getting displayed in the textbox. I was wondering how i could give a name to Textbox so all are shown.
for (int k = 0; k < tblCols; k++)
{
TableCell tc = new TableCell();
TextBox txtCompanyName = new TextBox();
txtCompanyName.Text = dsmissing.Tables[0].Rows[tblCols- 1]["NewCompanyName"].ToString();
tc.Controls.Add(txtCompanyName);
}
Replace this line
dsmissing.Tables[0].Rows[tblCols- 1]["NewCompanyName"].ToString();
With
dsmissing.Tables[0].Rows[k]["NewCompanyName"].ToString();
I assume you are talking about ID like below.
for (int k = 0; k < tblCols; k++)
{
TableCell tc = new TableCell();
TextBox txtCompanyName = new TextBox();
txtCompanyName.Text = dsmissing.Tables[0].Rows[k]["NewCompanyName"].ToString();
txtCompanyName.ID = Guid.NewGuid().ToString("N");
tc.Controls.Add(txtCompanyName);
}
I think you may have meant to do this:
for (int k = 0; k < tblCols; k++)
{
TableCell tc = new TableCell();
TextBox txtCompanyName = new TextBox();
//txtCompanyName.Text = dsmissing.Tables[0].Rows[tblCols-1 ["NewCompanyName"].ToString();
txtCompanyName.Text = dsmissing.Tables[0].Rows[k]["NewCompanyName"].ToString();
tc.Controls.Add(txtCompanyName);
}
Surely this will work and it is easy to understand
protected void Page_Load(object sender, EventArgs e)
{
button1();
}
protected void Page_Init(object sender, EventArgs e)
{
try
{
Label lbl = new Label();
lbl.ID = "lbl_label";
lbl.Text = "Enter the values";
form1.Controls.Add(lbl);
TextBox tb = new TextBox();
tb.ID = "tbx_textbox";
form1.Controls.Add(tb);
Button bt = new Button();
bt.ID = "bt_button";
bt.Text = "click";
form1.Controls.Add(bt);
}
catch (Exception ex) { }
}
public void button1()
{
Table table = new Table();
TableRow row = null;
TableCell cell = null;
TextBox tbx1 = this.Page.FindControl("tbx_textbox") as TextBox;
try
{
int a = int.Parse(tbx1.Text);
for (int i = 0; i < a; i++)
{
row = new TableRow();
cell = new TableCell();
TextBox tx = new TextBox();
tx.ID = "box" + i.ToString();
cell.Controls.Add(tx);
row.Cells.Add(cell);
table.Rows.Add(row);
form1.Controls.Add(table);
}
}
catch (Exception ex) { }
finally
{
table = null;
}
}

How can I get ID's of Dynamically generated Controls?

Hiiii,
In the following image the table & controls in it are generated dynamically.
Table is created onclick of "create table" button using values from dropdownlist which has no. of rows as values.
How can I get particular “Fileupload” & “Upload” button’s ID.
On click of “upload” button only fileupload control in same row as of that button should be accessed & it should not loop through all the fileupload controls in the table.
In my code, when I click Upload button in lower rows(say 3rd row) then it uploads the file selected in upper fileupload controls( here 1st n 2nd row along with 3rd row ) also.
I don’t want this. I just want to upload file from filupload control in the same row of clicked button.

plz Help me Out !!!
Thanx in Advance...
why not store a Row ID in the command argument for the button and then when the button is click you can use this to loop through all the rows untill the id matchs the row you are looking for, for example
foreach (DateRow test in table.Rows)
if ((test.findcontrol(uploadbutton) as Button).commandArgument = (Sender as Button).commandArgumrnt
{
//do stuff here
}
else
{
\\ do nothing
}
Hope this helps
