Collapse empty sections (height)

[Joshua Kent]

I have an issue where I have a series of lists or panels that might or might not contain data. If they don't contain data I want them to shrink down to their minimum height.

is this possible?

I attached screenshots I hope help illustrate what I am trying to accomplish.


**Update - Continuing to look at the documentation, it looks like perhaps docking or anchoring would accomplish this... but I am not positive how to go about it. I will continue playing... I welcome any assistance though.

Hello Joshua,

You can set the height of each container item (report section or panel item) to a really small number in the report constructor right after the InitializeComponent() method.

no change, I tried setting it to a pixel of 1 and also inch of 0 but both had no effect.

public FacultyForm()
{
    //
    // Required for telerik Reporting designer support
    //
    InitializeComponent();

    //
    // TODO: Add any constructor code after InitializeComponent call
    //
    pnlRelationships.Height = Unit.Inch(0);
    pnlRelationshipInstance.Height = Unit.Inch(0);
    detail.Height = Unit.Inch(0);
    pnlQuestionAnswers.Height = Unit.Inch(0);
    listQuestionAnswer.Height = Unit.Inch(0);
    listRelationship.Height = Unit.Inch(0);
    listRelationshipInstance.Height = Unit.Inch(0);
}

Hello Joshua,

Not sure how you've managed to instantiate the Unit class without new keyword. Additionally height of 1 pixel cannot be produced in browsers so they ignore it, height of 0 is invalid. Try the following instead:

pnlRelationships.Height = new Telerik.Reporting.Drawing.Unit(0.01, Telerik.Reporting.Drawing.UnitType.Inch);
....

Still no luck, I am sorry for the back and forth. I change the code as following. I am also trying to fix an issue where I have pages that are 90% blank so I also set the keeptogether attribute to false (in the design view and then in code behind after that didn't work).

I attached two screen shots of what is happening. I don't want to upload the entire pdf output because of confidential information in it. If you would prefer I can open up a support ticket with all of these files in it.

Thanks again for all of your assistance,

pnlRelationships.Height = new Telerik.Reporting.Drawing.Unit(.01D, Telerik.Reporting.Drawing.UnitType.Inch);
pnlRelationshipInstance.Height = new Telerik.Reporting.Drawing.Unit(.01D, Telerik.Reporting.Drawing.UnitType.Inch);
pnlQuestionAnswers.Height = new Telerik.Reporting.Drawing.Unit(.01D, Telerik.Reporting.Drawing.UnitType.Inch);
listQuestionAnswer.Height = new Telerik.Reporting.Drawing.Unit(.01D, Telerik.Reporting.Drawing.UnitType.Inch);
listRelationship.Height = new Telerik.Reporting.Drawing.Unit(.01D, Telerik.Reporting.Drawing.UnitType.Inch);
listRelationshipInstance.Height = new Telerik.Reporting.Drawing.Unit(.01D, Telerik.Reporting.Drawing.UnitType.Inch);

detail.Height = new Telerik.Reporting.Drawing.Unit(.01D, Telerik.Reporting.Drawing.UnitType.Inch);

pnlRelationships.KeepTogether = false;
pnlRelationshipInstance.KeepTogether = false;
pnlQuestionAnswers.KeepTogether = false;
listQuestionAnswer.KeepTogether = false;
listRelationship.KeepTogether = false;
listRelationshipInstance.KeepTogether = false;

detail.KeepTogether = false;

Hello Joshua,

Check out the following KB article that elaborates on why your report might end up with blank pages: Problem: Telerik Reporting renders blank pages.
If you are still having problems with the unused space when you've hidden an item, please prepare a sample runnable project, open a support ticket and attach it there. Once we review it, we would be able to provide you with more info.
