Using different controls in a editable column - kendo-asp.net-mvc

I have a kendoGrid initialized in cshtml. It use ajax binding.
The grid model looks like
int id,
int typeId,
string name.
string value.
The grid has 2 columns Name and Value and value is editable InCell.
For now grid works well with using by default usual textbox as editor.
I have to improve the grid to have possibility of using different controls in the "value" field depending of the value of "typeId".
I tried to use custom EditorTemplate for that but I cannot find a way to pass typeId to the template (the column is bound to "value").
Is it possible to pass there an extra parameter from the grid model or reach it somehow from the template?
Regards, Alexey

Which component of MV should transform raw data into user friendly format?

There is a structure that holds raw data (consider int) and a gui that should visualize this data. Gui part consists of a few models and and a few standard views (table and tree). The value should be presented either as a string or as a picture depend on user choice. There are some additional difficulties: in some cases the text is different for different elements - i.e., for the same column 0 normally means "Ok", but for a particular element it should be printed as "Yes", also depend on a user choice some columns should not print text for 0 values at all, living a cell empty and don't clutter the table; next, sometimes cell should show two values - e.g., current value and requested - something like "Yes -> No". This also applies to the case when user wants to see icons.
I see two options:
The model forms string text itself and store it somewhere (in the model item may be). The model also forms composite icon from base icons if it is needed. In that scenario I can use standard delegate and just use standard roles reimplementing QAbstractItemModel::data() method.
Reimplement delegates' paint() method (actually I need to reimplement delegates anyway because I need custom editors like QComboBox). The delegate can get any information it needs through the model and custom roles in paint() method and form the string or complex icon itself. As a suboption, I suppose, it's possible for a model to compose needed information itself, like returning std::tuple<int /*value*/, int /*requested value*/, int /*source element type*/, bool /*text or icon*/> in data() method for Qt::DisplayRole.
Update: I want add one thought about second option. Presumably delegates were introduced to handle the work of representing data. One of the consequences of that is the flexibility delegates can give. If you want to see a raw number in some column, you can just leave the default delegate, if you want some additional info presented in a cell you can set a special delegate for that specific column. And it seems you don't need even touch the model or something else.

Predicting the placeholder for a dynamic placeholder

I am using the Dynamic Placeholders from Fortis, but need to setup a page template where the Dynamic Placeholders contains renderings. I am setting the page template up, by setting layout detail on the standard values of the page template.
I have been unable to succeed in this, since the dynamic placeholder is postfixed by a GUID which is generated. Is there a way to predict this GUID? According to the documentation, the GUID is generated using the following logic:
Dynamic Placeholders simply use the rendering ID to create a unique placeholder name. If more than one dynamic placeholder with the same name is in a rendering it will also append on an incrementing number
I tried another approach, by using a home brewed dynamic placeholder library, which just prepended the dynamic placeholder with a sequential number, e.g. row1, row2, row3. But this approach makes the content editors unable to move rows in the experience editor, since the content inside the row is tied to a fixed number, which changes when the rows are moved.
As this question have been answered on sitecore.stackexchange.com, I want to bring the answer here as well. Big credit to Richard Seal and Thomas D.
Thomas D:
You can try to open the standard values item with the Experience Editor and add the renderings you like.
Richard Seal:
This is an alternative to the method mentioned by Thomas D.
The Fortis solution uses the UID for the rendering attached to the placeholder key that you enter. You can get this by changing to Raw Values view and copying the xml out of the renderings or final renderings field.
Find the rendering that contains your placeholder. There will be an xml element like this:
<r id="{CA76EB6F-2934-4B8A-BB6A-508A8E44A7C5}"
ph="body"
uid="{0FD41EBD-43CF-4647-8A0F-F1F1D2E00CCD}" />
There may be other fields too. The 2 that are important are id, which is the item id of your rendering item and uid, this is the unique rendering id that is added to your placeholder key.
The key is built like this: string.Format("{0}_{1}", placeholderName, renderingId);
So if you have a placeholder key called title, the key for the above xml snippet would be: title_{0FD41EBD-43CF-4647-8A0F-F1F1D2E00CCD}

Sitecore adding field labels to name value list

I am trying to display field titles above the appropriate columns in a name value list in Sitecore.
e.g. So instead of this
The name value list would look like this
Is there an easy method of achieving this apart from writing a custom control?
There is no out of the box support for applying a label to the values in a name value list, as #jammykam mentioned.
Since what you are storing would not typically be handled as key/value data, the name value list type might not be the best fit for what you are doing - think what you would have to do if you needed to add extra information e.g. title. I would suggest creating a simple template for 'person details' and then add 'people' items as sub-items of your existing item.
Seems like you want to give the authors a hint regarding the input fields and the best way to do that is using the "Short Description" field in "Help" section of the template under Standard Values. You can possibly enter something like as a hint.
A less optimal option would be to set up standard values for that field so the authors always have a value that suggests the type of input value for key and value.

Infragistics UltraGrid - How to use displayed values in group by headers when using an IEditorDataFilter?

I have a situation where I'm using the IEditorDataFilter interface within a custom UltraGrid editor control to automatically map values from a bound data source when they're displayed in the grid cells. In this case it's converting guid-based key values into user-friendly values, and it works well by displaying what I need in the cell, but retaining the GUID values as the 'value' behind the scenes.
My issue is what happens when I enable the built-in group by functionality and the user groups by a column using my editor. In that case the group by headers default to using the cell's value, which is the guid in my case, so I end up with headers like this:
Column A: 7F720CE8-123A-4A5D-95A7-6DC6EFFE5009 (10 items)
What I really want is the cell's display value to be used instead so it's something like this:
Column A: Item 1 (10 items)
What I've tried so far
Infragistics provides a couple mechanisms for modifying what's shown in group by rows:
GroupByRowDescriptionMask property of the grid (http://bit.ly/1g72t1b)
Manually set the row description via the InitializeGroupByRow event (http://bit.ly/1ix1CbK)
Option 1 doesn't appear to give me what I need because the cell's display value is not exposed in the set of tokens they provide. Option 2 looks promising but it's not clear to me how to get at the cell's display value. The event argument only appears to contain the cell's backing value, which in my case is the GUID.
Is there a proper approach for using the group by functionality when you're also using an IEditorDataFilter implementation to convert values?
This may be frowned upon, but I asked my question on the Infragistic forums as well, and a complete answer is available there (along with an example solution demonstrating the problem):
http://www.infragistics.com/community/forums/p/88541/439210.aspx
In short, I was applying my custom editors at the cell level, which made them unavailable when the rows were grouped together. A better approach would be to apply the editor at the column level, which would make the editor available at the time of grouping, and would provide the expected behavior.

Add Dropdown to infragistics WebDataGrid in Edit mode

I have two issues:
I have a complex object with Id and Text underneath. For display, I am using TemplateDataField with eval function. Can I bind the complex object to a BoundDataField?
The reason behind binding the complex object to BoundDataField is, I need to make it editable grid. I could not find any documentation or samples which uses Template field, and make that column editable. (I agree it might not be possible.) Now I need to put a dropdown, where user selects a value and I can assign it to the id field of my complex object. I am able to put a dropdown (using EditorProviders) to a bounddatafield, but how can I do it for the template data field described above?
Here is a link to the samples of Editing WebDatagrid: Controls & Application Samples
When using a TemplateDataField you are specifying what you want to use as the template and you can put an editor in that Field. Note that if you do put an editor in that field, you need to handle updates to the grid's value or list that your grid is bound to.
Note that if the values in your drop down have an id associated with them and that can be the value of the grid cell it would be better to use the DropDownEditorProvider with the grid having a bound field where that field is the id of the item that you are selecting.
