Dynamic Table

[Former Member]

Hi Experts,

I have an issue with Dynamic Table creation. This is the situation. I have an XML Where in i store table rows and columns. when the page loads i have to read the XML and i have to create row and columns dynamically as in the XML. I have done this . Problem is , i user wants to add a new column. i am giving one pop up window , where in i am getting column name. when pop up window closed, the dynamic table was not there .

What i am doing wrong?

I am creating dynamic table in init method. is it if control goes to anther window all context info will be lost?

Please help me on this.

Thank you,

Hi,

"I am creating dynamic table in init method. is it if control goes to anther window all context info will be lost?"

Dont store the view instance.

Create the table in the wdDomidifyView based on a condition either isFirstTime or else your custom one.

It would be really helpfull if you could post the code.

Hi Ayyapparaj,

This is the code

Hi,

Move the UI creation to the wdDoMoidify

Instead of this

IWDView view = (IWDView)this.wdControllerAPI;

use

IWDView view = view (param which is available as part of the wdDoModify)

Hi Ayyapparaj,

I tried that. when page loads, i am getting table and all columns and rows. But after pop get destroyed, i am getting empty screen.

Hi,

If the screen is totally empty their could be two reasons

1) Infinite loop

2) Usage of following code

IWDTransparentContainer container;

container.destroyAllChildren();
