In SAPUI5, smart table is a powerful tool that allows you to display and manipulate large amounts of data. One of its key features is the ability to sort and filter data based on a specific field. In this blog, we will explore how to sort and filter data in a smart table using SAPUI5.
Prerequisites:
Before we start, make sure you have a basic understanding of SAPUI5 and smart table. Also, you should have a basic knowledge of JavaScript, HTML, and CSS.
Example:
Let's say we have a smart table with the following fields: Name, Age, Gender, and City. We want to be able to sort the data based on the Age field and filter the data based on the City field.
Step 1: Create a Smart Table in SAPUI5
First, we need to create a smart table in SAPUI5. We can do this by using the SmartTable control in our XML view. Here is an example:
```<smartTable:SmartTable id="smartTable" tableType="ResponsiveTable" entitySet="Employees" ...>```
Step 2: Add Sorting and Filtering Capabilities
Next, we need to add the sorting and filtering capabilities to our smart table. We can do this by using the Sorter and Filter control in our controller. Here is an example:
```
onInit: function() {
var oSmartTable = this.byId("smartTable");
var oTable = oSmartTable.getTable();
var oSorter = new sap.ui.model.Sorter("Age", true);
oTable.getBinding("items").sort(oSorter);
var oFilter = new sap.ui.model.Filter("City", sap.ui.model.FilterOperator.EQ, "New York");
oTable.getBinding("items").filter(oFilter);
}
```
In the above code, we first get a reference to the smart table and its table control. Then, we create a sorter object and apply it to the binding of the table to sort the data based on the Age field. Similarly, we create a filter object and apply it to the binding of the table to filter the data based on the City field.
Step 3: Display the Smart Table
Finally, we need to display the smart table in our view. We can do this by adding the smart table control to our XML view. Here is an example:
```<mvc:View xmlns:smartTable="sap.ui.comp.smarttable" ...>
<smartTable:SmartTable id="smartTable" tableType="ResponsiveTable" entitySet="Employees" ...>
</smartTable:SmartTable>
</mvc:View>
```
Method 2 - Using beforeRebindTable
Step 1: Create a Smart Table in SAPUI5
First, we need to create a smart table in SAPUI5. We can do this by using the SmartTable control in our XML view. Here is an example:
```<smartTable:SmartTable id="smartTable" tableType="ResponsiveTable" entitySet="Employees" ...>```
Step 2: Add Sorting and Filtering Capabilities
Next, we need to add the sorting and filtering capabilities to our smart table using the HandleBeforeBind function. We can do this by defining the function in our controller and then adding it to the smart table control in our XML view. Here is an example:
Controller:
```
onInit: function() {
var oSmartTable = this.byId("smartTable");
oSmartTable.attachBeforeRebindTable(function(oEvent) {
var oBindingParams = oEvent.getParameter("bindingParams");
oBindingParams.sorter = new sap.ui.model.Sorter("Age", true);
oBindingParams.filters = [ new sap.ui.model.Filter("City", sap.ui.model.FilterOperator.EQ, "New York") ];
});
}
```
In the above code, we first get a reference to the smart table control and then define the HandleBeforeBind function. This function is called before data is retrieved from the backend and allows us to modify the binding parameters. In this case, we create a sorter object and assign it to the sorter property of the binding parameters to sort the data based on the Age field. Similarly, we create a filter object and assign it to the filters property of the binding parameters to filter the data based on the City field.
XML View:
```<mvc:View xmlns:smartTable="sap.ui.comp.smarttable" ...>
<smartTable:SmartTable id="smartTable" tableType="ResponsiveTable" entitySet="Employees"
beforeRebindTable=".onBeforeRebindTable" ...>
</smartTable:SmartTable>
</mvc:View>
```
In the above code, we add the HandleBeforeBind function to the smart table control using the beforeRebindTable property.
Step 3: Display the Smart Table
Finally, we need to display the smart table in our view. We can do this by adding the smart table control to our XML view. Here is an example:
```<mvc:View xmlns:smartTable="sap.ui.comp.smarttable" ...>
<smartTable:SmartTable id="smartTable" tableType="ResponsiveTable" entitySet="Employees"
beforeRebindTable=".onBeforeRebindTable" ...>
</smartTable:SmartTable>
</mvc:View>
```
Sorting and filtering data in a smart table is an important feature that can greatly enhance the user experience. By using the Sorter and Filter controls in SAPUI5, we can easily implement this functionality. With the example provided above, you should now be able to sort and filter data in your own smart tables.
This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
