Enable / Disable delete row and add row

Hagar Rachman posted over 8 years ago

I am using a igTreeGrid and I am trying to hide/show "delete row" and "add child row" buttons for each row based on some criteria.

I set up this code to run when "hover" event is fired, but it is never running: $("#treegrid > tbody > tr").hover(...);

Thank you for your help.

here is my code:

TheGrid = $("#treegrid");

TheGrid.igTreeGrid({
width: "100%",
//dataSource: gridData, //bound to flat data source,
autoGenerateColumns: false,
primaryKey: "bgt_rowid",
foreignKey: "bgt_prowid",
initialExpandDepth: 0,
updateUrl: "Services/BudgetService.asmx/Update",
autoCommit : true,
columns: [
{ headerText: "שם", key: "rowName" , width: "300px" , dataType: "string" },
{ headerText: "rowID", key: "bgt_rowid", width: "100px", dataType: "number" , hidden: true},//must column. without it the grid is not working properly.
{ headerText: "ParentID", key: "bgt_prowid", width: "100px", dataType: "number", hidden: true },//must column. without it the grid is not working properly.
//dynamically add columns
<%
foreach (Builder.Tarbut.DAL.BudgetColumn col in GridCols) {
Response.Write(string.Format("{{ headerText: \"{0}\", key: \"{1}\", dataType: \"number\" }},", col.ColTitle, col.ID));
}
%>

I've tried this method, and I can get the hover function to recognize the correct cell, but the evt.preventdefault and evt.stoppropagation are not stopping the delete button from showing.

This is my code block inside the iggridrendered function.

$("#notesGrid > tbody > tr").hover(function(evt){
                var rowID = $(evt.target).closest("tr").attr("data-id");
                var deleted = grid.igGrid("getCellValue", rowID, "IsDeleted");
                if (deleted == true) {
                    evt.preventDefault();
                    evt.stopPropagation();
                }
            });

Hello Hagar,

Thank you for posting in our forum.

When attaching the hover event please make sure that the target elements (treegrid > tbody > tr) are already rendered in the DOM.

You can attach the event in the grid’s rendered event, for example:

rendered: function(){

                $("#treegrid1 > tbody > tr").hover(function(evt){

                                …

                });

}

If you’d like to show the add/delete buttons only for specific rows you can cancel the event for the rows for which you don’t want to show the buttons, for example:

$("#treegrid1 > tbody > tr").hover(function(evt){

var rowID = $(evt.target).closest("tr").attr("data-id");

if(!hasChildren(rowID)){

                //cancels event and prevents the buttons from showing

                evt.preventDefault();

                evt.stopPropagation();

}

});

I’ve attached a sample for your reference where the add/delete button will be displayed only for the rows that already have chidren. They will not be displayed for rows that don’t have children.

Please refer to the attached sample and let me know if you have any questions.
