Case-sensitive search

[munawwars]

Need an ability to ignore case while searching through the table.

I just added toLowerCase...
item[config.filtering.columnName].toLowerCase().match(this.config.filtering.filterString.toLowerCase()));

I realize this is an old thread, but I tried your .toLowerCase() method for case insensitive filtering, however, when I add that, I get this error:
Error: Expression has changed after it was checked.

public changeFilter(data:any, config:any):any {
let filteredData:Array = data;
this.columns.forEach((column:any) => {

  if (column.filtering) {
  
    filteredData = filteredData.filter((item:any) => {
      return item[column.name].match(column.filtering.filterString);
    });
  }
});

if (!config.filtering) {
  return filteredData;
}

if (config.filtering.columnName) {
  
  return filteredData.filter((item:any) =>{
   
    item[config.filtering.columnName].match(this.config.filtering.filterString)});
}

let tempArray:Array<any> = [];
filteredData.forEach((item:any) => {
  let flag = false;
  this.columns.forEach((column:any) => {

    
        if (item[column.name].toString().match(this.config.filtering.filterString)) {
                
                  flag = true;
        }

        if(column.name == "name"){
              if (item[column.name].toLowerCase().toString().match(this.config.filtering.filterString)) {
                        
                        flag = true;
                }
            }
   
  });
  if (flag) {
    tempArray.push(item);
  }
});
filteredData = tempArray;

return filteredData;

}

See this Condition that is used for my project

if(column.name == "name"){
if (item[column.name].toLowerCase().toString().match(this.config.filtering.filterString)) {

                        flag = true;
                }

}
