Hello Yavor,
Yes I’ve seen this before, I already set the string conditions like you suggested.
But when I collect the filter string in the Event then the string looks like
“CONTAINS abc” or “DOES_NOT_CONTAIN abc” and so on…
But what has the filter string exactly looks like for every condition if we set this collected filter string programmatically somewhere else?
It works when I set “contains abc”.
But not if I set “does_not_contain abc” etc. (I user lower case)
The hamburger menu is gone and the grid didn’t respond anymore.
I use the Grid Filtering.Filter property like this:
List<IEnumerable<string>> Filter = new List<IEnumerable<string>>()
{
new List<string> { “FirstName”, “contains Andrew” } // => works};
or
List<IEnumerable<string>> Filter = new List<IEnumerable<string>>()
{
new List<string> { “FirstName”, “does_not_contain Andrew” } // => doesn’t work
};MyGrid.Filtering.Filter = filter
I thought the conditions have to be like as in the documentation:
https://www.htmlelements.com/docs/grid-filtering-sorting/
I tried this:
List<IEnumerable<string>> Filter = new List<IEnumerable<string>>()
{
new List<string> { “FirstName”, “startswith Paul” }// => the filter is working, but the filter column panel shows me “equal” instead of “starts with” for the first condition
};Thanks for the example it works in my use case. Now the new added columns show the data. Great!
There is one issue left, could you investigate why this line is necessary:
grid.Columns = new List<GridColumn>() { }; //TODO: remove
Without this line, the columns never change. But we bind the columns property
<Grid DataSourceSettings=”DataSettings” @ref=”grid” DataSource=”dataRecords” Columns=”@columns”></Grid>
So this should actually trigger to set the new columns when the property changed?
I do not understand this (you commented it as removal, may this is a workaround)
grid.Columns = new List<GridColumn>() { }; //TODO: remove
It has side effects.
The columns are changed but you lost the symbols in the header (Sort, Filter etc.)
For example:
<Grid @ref=”grid” DataSource=”dataRecords” Columns=”@columns” Sorting=”@sorting”></Grid>
GridSorting sorting = new GridSorting { Enabled = true };
private void AddColumn()
{GridColumn newColumn = new GridColumn(){ Label = columnsList[i], DataField = columnsList[i], SortOrder = GridColumnSortOrder.Desc };
columns.Add(newColumn);grid.Columns = new List<GridColumn>() { }; //TODO: remove
}
The sort order symbols get lost here (also sort symbols on existing columns)
