UI Builder Class Overview in SSRS Reports 

Hi all,

This UI Builder class is simple class with less code and less effort. UI Builder Class is needed when you want to customize your dialog which pop ups when you open a Report. UI Builder Class helps you to add run time lookups and other controls on the dialog form.

Step1 : Your Class must extends SrsReportDataContractUIBuilder

class SimpleDemoUIBuilder extends SrsReportDataContractUIBuilder
{
DialogField dialogEmplId;
DialogField dialogName;
boolean enable;
SimpleDemoContract contract;

}// two fields emplId and Name will reflect in the lookup in dialog form at the time of report opening.

Based on different scenarios, different methods are overridden as shown in the following examples:

1)  Grouping the dialog fields/Changing the layout of the dialog/Adding custom controls to the dialog.To customize the layout and add custom fields, override the build as shown below:

Step 2 :Override the build method

public void build()
{
contract = this.dataContractObject();
dialogEmplId = this.addDialogField(methodStr(SimpleDemoContract, parmEmplId),contract);

}// this method used for adding the field  which is from contract class.

Step 3 :Write this method to  get a lookup on a particular field (emplID)

private void emplIdLookup(FormStringControl emplIdlookup)
{
Query query = new Query();
QueryBuildDataSource qbds_EmplTable;
SysTableLookup sysTableLookup;

// Create an instance of SysTableLookup with the current calling form control.
sysTableLookup = SysTableLookup::newParameters(tableNum(FilterDemo), emplIdlookup);
// Add fields to be shown in the lookup form.
sysTableLookup.addLookupfield(fieldNum(FilterDemo,EmplId));
sysTableLookup.addLookupfield(fieldNum(FilterDemo,Name));
qbds_EmplTable = query.addDataSource(tableNum(FilterDemo));
sysTableLookup.parmQuery(query);
// Perform the lookup
sysTableLookup.performFormLookup();
}

Now,Override the postBuild() method and write following code :

public void postBuild()
{
super();

//get the field to override by providing the data contract object and the associated attribute/method

dialogEmplId = this.bindInfo().getDialogField(this.dataContractObject(),methodStr(SimpleDemoContract,parmEmplId));

//

register the method we want to override

dialogEmplId.registerOverrideMethod(methodStr(FormStringControl, lookup),

methodStr(SimpleDemoUIBuilder,emplIdLookup), this);

dialogEmplId.lookupButton(2);

}

Step4 : Override this method

public void getFromDialog()
{
contract = this.dataContractObject();
super();
}

Step5 : Override this method

public void initializeFields()
{
contract = this.dataContractObject();
}

One important part has to be added to the contract class i.e in class declaration, the following part has to be updated.

[DataContractAttribute,SysOperationContractProcessingAttribute(classstr(SimpleDemoUIBuilder))]

That's it guys ..
