i want to check condition before save   but still not work what im wrong ?

how to solve it

I was going great with the web project, until i found this issue, if i use the dropdownlist outside of the grid, it will display just fine, even if i assign it to the toolbar template, but when i assign it to grid's pop-up editor, it doesn't display the dropdownlist for me to create a new data, it just displays the blank text, can someone explain to me how to use dropdownlist in editor, i tried the custom editor but it doesn't help.

Hi,

I have a scatter line chart that is supposed to show incidents that occur simultaneously. I am almost there, but have some issues I haven't been able to solve:

1) The color of the lines and markers should all be the same. As it is the color seems to be random.

2) Same goes for the tooltip, as you can see some color combinations makes for very poor visibility. I have tried to set .Color("white") on the tooltip, but it has no effect.

3) Is it possible to set the size of the chart depending on the amount of data? If there are many simultaneous incidents the chart needs to be higher.

4) I would like to have labels instead of tooltips, labels that looks like the toopltips I get when hovering over a line, but they should always be visible for all lines.Is this possible?

Best regards,

Henrik

Hi,

I have the grid below and I have added a dropdown list in one of the cells. What I want to do is for each item in the dropdown list I want to set a color.

I.e. item 1 has a blue background, item 2 has a green background etc.

Also I want the selected items background color to also be the same as the item they have selected.

Any Ideas on what I can do to achieve the above?

Below is the grid I am working with:

@using System.Collections.Generic;

@model IEnumerable<TelerikChecklist.Models.ProductViewModel>
    
@(Html.Kendo().Grid(Model)
    .Name("gridDropDown")
    .Columns(columns =>
    {
        columns.Bound(p => p.ProductName);
        columns.ForeignKey(p => p.CategoryID, (System.Collections.IEnumerable)ViewData["categories"], "CategoryID", "CategoryName")
            .Title("Category").Width(150);
    })
    .Editable(editable => editable.Mode(GridEditMode.InCell))
    .Pageable()
    .Scrollable()
    .HtmlAttributes(new { style = "height:250px;" })
    .DataSource(dataSource => dataSource
        .Ajax()
        .Batch(true)
        .PageSize(20)
        .ServerOperation(false)
        .Events(events => events.Error("errorHandler"))
        .Model(model =>
        {
            model.Id(p => p.ProductID);
            model.Field(p => p.ProductID).Editable(false);
            model.Field(p => p.CategoryID).DefaultValue(1);
        })

        .Read(read => read.Action("ForeignKeyColumn_Read", "Home"))
        .Update(update => update.Action("ForeignKeyColumn_Update", "Home")).Events(e => e.Change("Category"))
        .Create(create => create.Action("ForeignKeyColumn_Create", "Home"))
        .Destroy(destroy => destroy.Action("ForeignKeyColumn_Destroy", "Home"))

    )
    )

How can I get the original values of the row when calling an update function?

My main issue is that we have a few tables where the primary key is a value we allow to be changed. However, the default auto-generated update functions will fail on update if that value is changed in the grid editor because it won't be able to lookup the row you're updating since it only knows what you want to change the value to and tries to look the row up by the new value.

How can we handle this situation?

I am just wondering how to access the buttons that allow you to choose either to edit the current recurrence or edit the entire recurrence series. I would like to call a function when one of them is clicked. I have attached a picture of the buttons for your convenience.

Hi there - apologies if this is elsewhere, but I've searched and can't find an answer. I have good C# experience, but I'm relatively new to Telerik/Kendo etc,

I am aware of the AllPages(true) option for the Excel printout. What I would like to do on my Grid is to have two excel buttons, one that will export the current page, and one which will export all data.

Is this possible? From what I can see, you can only define one Excel Button on the toolbar.

Thanks in advance.

I'm trying the grouping in Grid I want to display the sum of the column as ClientGroupHeaderColumnTemplate  or ClientHeaderTemplate but doesn't  seem to be working, it only shows as a ClientFooterTemplate. :

 

I have got a problem where my grid columns expect a detailed name ("CityFrom" and "CityTo" - those are strings), but a method returns "Name" property. How can I map the result to the columns without duplicating the code?

Here is grid:

 

Here is method:

Error I am getting is in console:

 

On grid I could use .DataTextField("Name"), but I don't have this option here. Both filters have got the same set of values - cities from database. Any ideas what can I do elegantly here?
