-
Description: Returns a string representation of the specified object.
-
Example:
Serialize(Queues.testQueue.arg1)
Serialize(Queues.testQueue.arg1)
-
Function:
T Deserialize<T>(string obj)
-
Description: Returns an object of type T. Takes as input a valid JSON string representation of an object.
-
Example:
WhereDeserialize(Of AppsFile)(textV)
Deserialize(Of AppsFile)(textV)textV
is a variable of type Tex, containing the serialized string of the object.
-
Function:
T? App.QueryParam<T>((string param, T? defaultValue = default(T))
-
Description:
-
If the query parameter is passed in the URL , the function returns that value deserialized based on generic type T.
-
If the deserialization fails or if the query parameter is not passed in the URL, then the function returns the default value.
-
-
Example:
App.QueryParam(Of AppsFile)("file", new AppsFile("https://i0.wp.com/ imagelinkmri.com/wp-content/uploads/2021/08/imagelink-04.png"))
App.QueryParam(Of AppsFile)("file", new AppsFile("https://i0.wp.com/ imagelinkmri.com/wp-content/uploads/2021/08/imagelink-04.png"))
-
Function:
string App.QueryParam(string param, string? defaultValue = "")
-
Description:
-
If the query parameter is passed in the URL, the function returns that value as string.
-
If the query parameter is not passed in the URL, the function return the default value.
-
-
Example:
App.QueryParam("stringVariable", "defaultText")
App.QueryParam("stringVariable", "defaultText")
-
Function:
List<T> AddItemToList<T>(List<T> list, T value)
-
Description: Given a list of type T, appends an item to the list and returns the updated list.
-
Example:
AddItemToList(Of String)(stringList, "AddMe")
AddItemToList(Of String)(stringList, "AddMe")
-
Function:
List<T> UpdateListItemAtIndex<T>(List<T> list, int index, T value)
-
Description: Given a list of type T, updates the item at the specified index, and returns the updated list.
-
Example:
UpdateListItemAtIndex(Of String)(stringList, MainPage.EditGrid.RowIndex,"UpdateValue")
UpdateListItemAtIndex(Of String)(stringList, MainPage.EditGrid.RowIndex,"UpdateValue")
-
Function:
List<T> DeleteItemFromList<T>(List<T> list, int index)
-
Description: Given a list of type T, deletes the item at the specified index and returns the updated list.
-
Example:
DeleteItemFromList(Of String)(stringList, MainPage.EditGrid.RowIndex)
DeleteItemFromList(Of String)(stringList, MainPage.EditGrid.RowIndex)
-
Function:
ListSource<T> Fetch<T>(FilterGroup group = null, PaginationProps paginationProps = null, SortOption[] sortOptions = null, string[] selectedFields = null, ExpansionFieldOption[] expansionFieldOptions = null )
-
Description: Returns all the records of an entity object, according to the mentioned parameters.
-
Example:
Fetch(of AlexEntity)(createFilterGroup(Nothing, New FilterGroup(){createFilterGroup(New QueryFilter(){addFilter(MainPage.EditGrid.SearchColumn, "contains", MainPage.EditGrid.SearchTerm)}, Nothing, 0)}, 0), New PaginationProps(MainPage.EditGrid.PageStart, MainPage.EditGrid.PageLimit), New SortOption(){addSortOption(MainPage.EditGrid.SortColumn, Not(Not(MainPage.EditGrid.isDescending)))}, Nothing, New ExpansionFieldOption(){addExpansionFieldOption("CreatedBy", New String(){"Id","Name"}), addExpansionFieldOption("UpdatedBy", New String(){"Id","Name"})})
Fetch(of AlexEntity)(createFilterGroup(Nothing, New FilterGroup(){createFilterGroup(New QueryFilter(){addFilter(MainPage.EditGrid.SearchColumn, "contains", MainPage.EditGrid.SearchTerm)}, Nothing, 0)}, 0), New PaginationProps(MainPage.EditGrid.PageStart, MainPage.EditGrid.PageLimit), New SortOption(){addSortOption(MainPage.EditGrid.SortColumn, Not(Not(MainPage.EditGrid.isDescending)))}, Nothing, New ExpansionFieldOption(){addExpansionFieldOption("CreatedBy", New String(){"Id","Name"}), addExpansionFieldOption("UpdatedBy", New String(){"Id","Name"})})Note:TheFetch()
function is used by the Query builder and it is asynchronous.
-
Function:
T FetchOne<T>(FilterGroup group = null, PaginationProps paginationProps = null, SortOption[] sortOptions = null, string[] selectedFields = null, ExpansionFieldOption[] expansionFieldOptions = null)
-
Description: Returns a single record of an entity object, according to the mentioned parameters.
-
Example:
FetchOne(of Employee)( createFilterGroup(new QueryFilter(){addFilter( MainPage.EditGrid.SearchColumn,"contains",MainPage.EditGrid.SearchTerm)}), new PaginationProps(MainPage.EditGrid.PageStart, MainPage.EditGrid.PageLimit), new SortOption(){ addSortOption( MainPage.EditGrid.SortColumn,MainPage.EditGrid.isDescending) } )
FetchOne(of Employee)( createFilterGroup(new QueryFilter(){addFilter( MainPage.EditGrid.SearchColumn,"contains",MainPage.EditGrid.SearchTerm)}), new PaginationProps(MainPage.EditGrid.PageStart, MainPage.EditGrid.PageLimit), new SortOption(){ addSortOption( MainPage.EditGrid.SortColumn,MainPage.EditGrid.isDescending) } )Note:TheFetchOne()
function is used by the Query builder and it is asynchronous.
-
Function:
FilterGroup createFilterGroup(QueryFilter[] queryFilters, FilterGroup[] groups = null, int isAnd = 0)
-
Description: Given an array of query filters and filter groups, generates a filter group.
-
Example:
createFilterGroup(Nothing, New FilterGroup(){createFilterGroup(New QueryFilter(){addFilter(MainPage.EditGrid.SearchColumn, "contains", MainPage.EditGrid.SearchTerm)}, Nothing, 0)}, 0)
createFilterGroup(Nothing, New FilterGroup(){createFilterGroup(New QueryFilter(){addFilter(MainPage.EditGrid.SearchColumn, "contains", MainPage.EditGrid.SearchTerm)}, Nothing, 0)}, 0)
