Record Deletion in a Table

[jnmurthi]

Hi All,

I am having a problem with deleting records from the table.

I am not using any checkboxes, but using the default selection provided by webdynpro tables. Now, how do I need to select multiple records and delete them. Also, is there any facility delete all records in the table.

Please do help me and gain reward points.

Regards,

Murthy.

i would suggest a different way, thats how i would do it.

While creating the table, assign a key to each row. This would be a kind of index. now on select of that key, you can use the key value to invalidate that particular row using the regular functionality.

will send u the code after trying it. i have used this key feature to check for multiple selection in checkboxes, i believe we can use the same feature for deleting the row.

<b>Hi...

For Deleting All the records without selecting

Try thid code...

wdContext.node<"NodeName">.invalidate();

For Deleting Multiple Selection(ie Only Selected Rows)

Try this Code...

for(int i=wdContext.node<"NodeName">().size()-1;i>=0;i--)
 {
   if(wdContext.node<"NodeName">().isSelected(i))
   {
     wdContext.node<NodeName>().removeElement(wdContext.node<"NodeName">().get<"NodeName">ElementAt(i));
    }
}

Hi Narayana,

Take a button(say delete) inside view layout.

Inside the actions of the delete button use this code.

try {

for (int i = wdContext.node<put node name here>().size() -1 ; i >= 0 ; --i)

{

if ((!wdContext.node<put node name here>().isMultiSelected(i))

&& (wdContext.node<put node name here>().getLeadSelection()

!= i)) {

continue;

}

else

{

wdContext. node<put node name here >().removeElement(

wdContext node<put node name here>().get<put node name>ElementAt(i));

}

}

} catch (Exception e) {

wdComponentAPI.getMessageManager().reportException(

"NO RECORD TO DELETE",

false);

}

Hi,

Change the selectionmode property of the Table to 'multi' , then you will be able to select multiple rows. Then delete the multipleselected rows in the table through the corresponding API.

Hi,

For deleting all records, use wdContext.node<TableNode>().invalidate();

Hai,

To delete all the record form the table simply

wdcontext.nodeTable().invalidate();

For multiple selection

Make the selection propty of table =multiple

in code

if(wdContext.nodeTable().getTableElement(i).ism,ultiSelected())// true when the row selected

make sure node selection proprty=o..n or 1..n

<b>Hi

You can use Invaildate() function to delete all the records in the table

Use this Code in your application

WdContext.<nodename>.invalidate();
