I have added controls to table cell but not find any control
This appears to be an issue with the execution order. Remember that your controls are not added until after your click event. So when your button click fires, the controls need to have been re-added before you can check for their existence.
(I would post this as a comment, but evidently, as I am new, I don't have enough points)
pass in the Page as the root and see if the control you are looking for comes back
private Control FindControlRecursive(Control rootControl, string controlID)
{
if (rootControl.ID == controlID) return rootControl;
foreach (Control controlToSearch in rootControl.Controls)
{
Control controlToReturn =
FindControlRecursive(controlToSearch, controlID);
if (controlToReturn != null) return controlToReturn;
}
return null;
}
You have simply forgotten to add the table itself to the page's control-collection.
Page.Controls.Add(table);
(it would be better to add it to a container control like PlaceHolder or Panel instead)

I have dynamically created buttons, eg 1,2,3,4,5,6,7,8; if I select 2,3,4, then I can't select 6 and skip 4. Or you can say, if I select 2,3,4,5,6 then if want to deselect 4 then I have to deselect 5 and 6 first.

I have a task called Find and Replace in the DataGridView - It's completed.But i want the replaced count in the message box.
Can anyone help me how to achieve this? Below is my Find and Replace code:
private void btnFindandReplace_Click(object sender, EventArgs e)
{
f.cmbColumnCombo.DataSource = cmbList;
f.ShowDialog();
if (recNo > 0)
recNo = recNo - 30;
LoadPage(MyFOrmat, true);
}
public void LoadPage(string Format, bool isFindAndReplace = false)
{
int startRec;
int endRec;
if (currentPage == PageCount)
{
endRec = (int)maxRec;
}
else
{
endRec = (int)pageSize * currentPage;
}
dataGridView1.Rows.Clear();
if (recNo == 0)
{
dataGridView1.Columns.Clear();
}
int rowindex = 0;
startRec = recNo;
for (int RowCount = startRec; RowCount <= endRec; RowCount++)
{
if (datfile[RowCount].ToString() != "" )
{
if (RowCount == 0)
{
string[] column = datfile[RowCount].Split('þ');
for (int i = 0; i < column.Length - 1; i++)
{
if (column[i].ToString() != "") //if (column[i].ToString() != "" && column[i].ToString() != "\u0014")
{
DataGridViewTextBoxColumn dgvtxtcountry = new DataGridViewTextBoxColumn();
dgvtxtcountry.HeaderText = column[i].ToString();
dgvtxtcountry.Name = column[i].ToString();
dataGridView1.Columns.Add(dgvtxtcountry);
cmbList.Add(column[i]);
// dataGridView1.Columns["Sent Date"].DefaultCellStyle.Format = "dd/MM/yyyy";
i += 1;
}
}
}
if (RowCount != 0)
{
dataGridView1.Rows.Add();
string[] column = datfile[RowCount].Split('þ');
int index = 0;
for (int i = 1; i < column.Length - 1; i++)
{
if (column[i].ToString() != "\u0014")
{
//if (i == 3)
//{
// dataGridView1.Rows[rowindex].Cells[index].Value = Convert.ToDateTime(column[i]).ToString(Format);
//}
//else
//{
dataGridView1.Rows[rowindex].Cells[index].Value = column[i].Trim('þ');
//}
if (StaticVar.FnR == true && index == StaticVar.colindx)
{
if ((column[i]).Contains(StaticVar.Find) != null)
dataGridView1.Rows[rowindex].Cells[index].Value = column[i].Replace(StaticVar.Find, StaticVar.Replace);
}
if (StaticVar.DateFormat != "" && StaticVar.DateFormat != null)
{
if (StaticVar.datecolidx == ((i - 1) / 2))
{
dataGridView1.Rows[rowindex].Cells[index].Value = Convert.ToDateTime(column[i]).ToString(StaticVar.DateFormat);
}
}
index += 1;
i += 1;
}
}
rowindex += 1;
}
}
recNo += 1;
}
}
Declare the replaced variable and increment it every time you replace a value. Show a message box at the end of the method.
public void LoadPage(string Format, bool isFindAndReplace = false) {
int replaced = 0;
....
if ((column[i]).Contains(StaticVar.Find) != null) {
dataGridView1.Rows[rowindex].Cells[index].Value = column[i].Replace(StaticVar.Find, StaticVar.Replace);
replaced++;
}
....
if(isFindAndReplace)
MessageBox.Show(string.Format("{0} occurrence(s) replaced.", replaced));

But the problem is in RecreateDateControls() function ImageButton Counter cnt2 is zero therefore previous controls are not recreated what should i do for it.

On a WinForm application, I have a form that contains a GridView, I am filling the GridView by collecting the data from a database.
I Have a pictureBox that contains a Loading.gif image.
What do i want is to view the PictureBox during retrieving the data from the database.
I tried the bellow code, but it did not work...
private void Generate_Button_Click(object sender, EventArgs e)
{
pictureBox1.Visible = true;
{
Generate_Button.Text = "Done";
if (conn.State == ConnectionState.Closed)
conn.Open();
radGridView1.Columns.Add(new GridViewTextBoxColumn("Account No."));
radGridView1.Columns[0].Width = 85;
bool DataAvailable = false;
if (MainAccNo_TextBox.Text == "" && CurencyNo_TextBox.Text == "")
{
if (SeparateBy_DropDownList.Text == "4")
{
for (int i = 1; i <= 9; i++)
{
for (int j = 0; j <= 9; j++)
{
for (int k = 0; k <= 9; k++)
{
for (int l = 0; l <= 9; l++)
{
SqlCommand cmd_AccNo = new SqlCommand("Select distinct(AccNo) from JourTrans where AccNo like '" + i + "" + j + "" + k + "" + l + "%'", conn);
SqlDataReader reader_AccNo = cmd_AccNo.ExecuteReader();
radGridView1.Rows.Add(i + "" + j + "" + k + "" + l);
while (reader_AccNo.Read())
{
Accounts.Add(reader_AccNo["AccNo"].ToString());
radGridView1.Rows.Add(reader_AccNo["AccNo"].ToString());
DataAvailable = true;
}
reader_AccNo.Close();
if (DataAvailable == true)
{
radGridView1.Rows.Add("");
DataAvailable = false;
}
else
radGridView1.Rows.RemoveAt(radGridView1.Rows.Count - 1);
}
}
}
}
}
}
}
pictureBox1.Visible = false;
}

Do your retrieving in another thread and use Dispatcher so that you can access your controls from that thread:
pictureBox1.Visible = true;
Dispatcher.BeginInvoke(new MethodInvoker(() =>
{
for (int i = 1; i <= 9; i++)
{
//Here I am retrieving data from the database
}
pictureBox1.Visible = false;
}));
So I've got an array of integer. I want to use a loop and exclude integers that makes the equation true. So that would be like
for (int n = 0; n < first9char.Length; n++ ) {
if (first9char[n] == clickValue) {
first9char[n] = first9char[n + 1];
But then it only changes the value that is equal to not changing whole array. So is there any way to do this?
I want to use it in this loop.
if (UserSquareMethod.clickedBoxes[0] == -1) {
MessageBox.Show("You have not selected any box");
} else {
int i = 0;
do {
if (textButtonArray[clickedBox[i]].Text == "" || clickValue == "") {
textButtonArray[clickedBox[i]].Text = clickValue;
textButtonArray[clickedBox[i]].Font = new Font(textButtonArray[clickedBox[i]].Font.FontFamily, 14, FontStyle.Bold);
}
else
{
textButtonArray[clickedBox[i]].Text += "," + clickValue;
textButtonArray[clickedBox[i]].Font = new Font(textButtonArray[clickedBox[i]].Font.FontFamily, 5, FontStyle.Regular);
string[] first9char = textButtonArray[clickedBox[i]].Text.Split(new string[] { "," }, StringSplitOptions.None);
for (int j = 1; j < first9char.Length; j++)
{
for (int k = j - 1; k >= 0; k--)
{
if (first9char[j] == first9char[k])
{
if (clearNumberClicked == true)
{
first9char = Array.FindAll(first9char, x => x != clickValue);
label2.Text = first9char[0];
//int n = 0;
//for (int p = 0; p < first9char.Length; p++)
//{
// if (first9char[p] != clickValue)
// {
// first9char[n] = first9char[p];
// n++;
// label2.Text += "," + first9char[n];
// }
// }
//for (int n = 0; n < first9char.Length; n++ ) {
//if (first9char[n] == clickValue) {
// first9char[n] = first9char[n + 1];
// for ( int p = 0; p < n; p++) {
//}
//}
//}
MessageBox.Show("Clear the number" + first9char[(first9char.Length - 1)] + "and " + clickValue + " " + first9char.Length);
}
else {
first9char[j] = "";
textButtonArray[clickedBox[i]].Text = first9char[0];
MessageBox.Show("You cannot enter the same number again!"+ first9char[j]+j);
for (int m = 1; m < (first9char.Length - 1); m++) {
textButtonArray[clickedBox[i]].Text += ","+ first9char[m];
}
}
}
}
}
if (textButtonArray[clickedBox[i]].Text.Length > 9)
{
textButtonArray[clickedBox[i]].Text = first9char[0] + "," + first9char[1] + "," + first9char[2] + "," + first9char[3] + "," + first9char[4];
MessageBox.Show("You cannot enter more than 5 numbers, please clear the box if you want to enter different number." + textButtonArray[clickedBox[i]].Text.Length);
}
}
i++;
}
while (clickedBox[i] != -1);
}
}
I would use LINQ for this:
first9char = first9char.Where(x => x != clickValue).ToArray();
It just means "pick the items that don't match". If you can't use LINQ for some reason, then just keep another counter, and make sure to only loop to n from there on in:
int n = 0;
for(int i = 0; i < first9char.Length; i++) {
if(first9char[i] != clickValue) {
first9char[n] = first9char[i];
n++;
}
}
Clean and efficient.
