Dear expert
Thanks for your feed back.
Hi Manh,
For column names, number of columns and number of rows:
For the value of a specific cell:
In this case, @Tag.text will get the value of cell(0,20).
Keep in mind that the column index used in “columnSelect”, is according to the AlarmWindow Configuration page.
If you want to handle ComboBox events, you have to associate an event handling method with the event.
In this example below, we are associating the “SelectionChanged” event with its handler:
Then you have to write the code you want to be executed when the event occurs:

Dear expert
Thank for your useful feedback. I got your explanation.
I have a small doubt when declare ComboBox with instruction " TComboBox Combo = CurrentDisplay.GetControl(“cobox”) as TComboBox"*
If I put this instruction inside the public void method, no error happen.
If I put this instruction outside the public void method, the error happen like below pictue
Hi Manh,
In the following explanation we will show you how to create a global ComboBox declaration. We will declare the variable Combo and Combo2 as of type TComboBox. The function InitializeCombo is then created, which aims to initialize the variable Combo and Combo2. In DisplayIsOpening, the function called InitializeCombo is executed to initialize the Combo and Combo2 variables and we did this example adding the values “123” and “abc”. In this way, the values are already inserted in the ComboBox.
public TComboBox Combo;
public TComboBox Combo2;
public void InitializeCombo()
{
Combo = CurrentDisplay.GetControl("cobox") as TComboBox;
}
public void InitializeCombo2()
{
Combo2 = CurrentDisplay.GetControl("Combo") as TComboBox;
}
public void DisplayOpening()
{
InitializeCombo();
Combo.Items.Add("abc");
InitializeCombo2();
Combo2.Items.Add("123");
}
Outside of methods , you can only declare variables, to execute the GetControl() must be into a methods DisplayOpening, DispayIsOpen, DisplayClosing or any other methods called by those three methods.

Dear Expert.
Thank for your quickly feed back.
I have a simple example like this.

=> When runtime, I have a result as below
Hi Thanos,
Thank you for clarifying your question. We have carefully reviewed your query and successfully reproduced the reported behavior in our system.
To ensure that the Tag assigned to combo.SelectedItem is updated in the correct order, we recommend making the following modification in the CodeBehind:
public void handler(object sender,SelectionChangedEventArgs e)
{
@Tag.combox=this.combo.SelectedItem.ToString();
@Dataset.Query.QueryT.SqlStatement="SELECT * FROM "+@Tag.combox;
}
By implementing this change, we were able to achieve the desired final result, as you explained.
We hope this solution is useful for you. If you have any other questions, please do not hesitate to contact us.
