[chotu27]

Hi All,   Can anyone Help how to build Selection ID or Selection Manager for custom table visual.

Hello @chotu27,

You should use something like this:

options.dataViews[0].table.identity.map((identity: DataViewScopeIdentity) => {
    const categoryColumn: DataViewCategoryColumn = {
        source: this.dataView.source.table.columns[0],
        values: null,
        identity: [identity]
    };

    return this.host.createSelectionIdBuilder()
        .withCategory(categoryColumn, 0)
        .createSelectionId();
});

Hi Ignat

I am not able to find any 

this.dataView.source

on the power bi dataview objects. Could you please help me in the retrieving that or any documentation which would help me get the source of that object?

Hello @chotu27

You can get a dataView object from option of the update method.

public update(options: VisualUpdateOptions) {
    const dataView: DataView = options && options.dataViews && options.dataViews[0];
}

I need an example of what you are talking about, "Selection Manager" does not compute.

@Greg_Deckler

In some the information i have read still the creation of selection manager for table visual is not available we have only selection manager for categorical view not for the table view .

Is that True????

[Greg_Deckler]

I still don't understand what you mean by selection manager. Selecting what? Managing what? Can you select columns to put into a table, yes.

@Greg_Deckler

If you know about creating custom visuals in power bi then you can understand what is selection manager.

It is about slicing the data based on selections made in visual like what we we have now in  default table visual in power bi.

I have created my own Customized table visual but iam not able to create the functionality of slicing and clicking in visual (Selection manager Builder)
