Is there any UI Element with "Select All" and "Deselect All" Option?

[Former Member]

Hi,

Can any one please help me in finding such a control in Web DynPro which is like a table and has the option to select or deselect all the rows of the table?

HI Smriti,

Insert one mode column to the table with Chechbox as editor. Create a boolean context variable (Check) inside table node and bind to Checked Property.

Create 2 buttons, Select All and Deselect All.

In SelectAll button's action, write this code

IPrivate<View>.I<Table>Node tNode=wdContext.node<Table>().;

for(int i=0;i<tNodesize();i++)

{

tNode.get<Table>ElementAt(i).setCheck(true);

}

In DeselectAll button's action, write this code

IPrivate<View>.I<Table>Node tNode=wdContext.node<Table>().;

for(int i=0;i<tNodesize();i++)

{

tNode.get<Table>ElementAt(i).setCheck(false);

}

How about this?

create a toolbartogglebutton and onaction, do something like this

// toggleSelect to record the state of button

boolean tf = wdContext.currentContextElement().getToggleSelect();

// assume you have the node call projects

wdContext.nodeProjects().setLeadSelection(-1);

if (tf){

for (int i = 0; i < wdContext.nodeProjects().size(); i++) {

wdContext.nodeProjects().setSelected(i,false);

};

wdContext.currentContextElement().setToggleSelect(false);

} else {

for (int i = 0; i < wdContext.nodeProjects().size(); i++) {

wdContext.nodeProjects().setSelected(i,true);

}

wdContext.currentContextElement().setToggleSelect(true);

}

So you can toggle between select all and deselect all.

Hi Yung siu wai,

I am getting an exception on writing this code at the line:

"wdContext.nodeProjects().setLeadSelection(-1);"

Exception: "selection cardinality does not allow to clear the selection "

The only way to hightlight, is really just changing the text to blue instead of black.

Hi ,

Your selection error is related to your context node setting where you probably have select as 1..n so WD does not allow you to set NoSelection. Fix it by changing it to 0..n.
