Grid's numeric column does not render editor

[Gergo]

Hi,

I have a strange error with Kendo Grid. I have a model defined :

var allocationGridModel = new kendo.data.Model({

           id: "Symbol",

           fields: {

               IsCheckedForDelete: { type: "boolean" },

               AssetClassCode: { type: "string", editable: false, nullable:false },

               AssetClassColor: { type: "string", editable: false, nullable:false  },

               Symbol: { type: "string", editable: false, nullable:false  },

               SecurityDescription: { type: "string", editable: false, nullable:true  },

               TargetAllocation: { type: "number", editable: true, validation: { min: 0.01}, nullable:false  },

               DriftMin: { type: "number", editable: true, nullable:false  },

               DriftMax: { type: "number", editable: true , nullable:false },

               MinBuyWeight: { type: "number", editable: true, nullable:true  },

               MinBuyValue: { type: "number", editable: true , nullable:true },

               MinSellWeight: { type: "number", editable: true, nullable:true  },

               MinSellValue: { type: "number", editable: true , nullable:true },

               SellOrder: { type: "number", editable: true, nullable:false  },

               IsInFavorites: { type: "boolean", editable: false,nullable:true },

               Equivalences : {type : "string", editable:false,nullable:true }

           }

       });

I have a grid which uses this model. In the grid I have rowTemplates defined. What I observed is, if in one of the columns which is editable, I put a 0 value and after, if I try to re-edit the same cell afterwards the numeric text box in the grid cell is not rendered. In some cases a simple input is rendered in other cases the value 0 disappears and no control is displayed in the cell.

Here is the column definition for the marked column in the attached image:

{

          field: "MinBuyWeight",

          title: "Min Buy Weight",

          template: '<div style="text-align:right;">#= kendo.toString(MinBuyWeight,"0.00") # % OR</div>',

          width: "90px"

      }

Do you have any kind of ideas what am I doing wrong?

Thanks in advance!!

Hi Gergo,

I suspect that the behavior you have described is caused by incorrect model definition. Looking at the snippet you have pasted it seems that you are creating a Model instance instead of defining a model declaration. Thus, you should change it to something similar to the following:

        var AllocationGridModelType = kendo.data.Model.define({
           id: "Symbol",
           fields: {
               IsCheckedForDelete: { type: "boolean" },
               AssetClassCode: { type: "string", editable: false, nullable:false },
               AssetClassColor: { type: "string", editable: false, nullable:false  },
               Symbol: { type: "string", editable: false, nullable:false  },
               SecurityDescription: { type: "string", editable: false, nullable:true  },
               TargetAllocation: { type: "number", editable: true, validation: { min: 0.01}, nullable:false  },
               DriftMin: { type: "number", editable: true, nullable:false  },
               DriftMax: { type: "number", editable: true , nullable:false },
               MinBuyWeight: { type: "number", editable: true, nullable:true  },
               MinBuyValue: { type: "number", editable: true , nullable:true },
               MinSellWeight: { type: "number", editable: true, nullable:true  },
               MinSellValue: { type: "number", editable: true , nullable:true },
               SellOrder: { type: "number", editable: true, nullable:false  },
               IsInFavorites: { type: "boolean", editable: false,nullable:true },
               Equivalences : {type : "string", editable:false,nullable:true }
           }
       });

Hi Rosen,

I've done as you suggested(create model with kendo.data.Model.define()), but the problem persists .
I am pretty sure that it has to do something with the 0 value. 
In the model I have the field set as nullable, but after assigning the 0 value to that field, afterwards it can't be edited.

Do you have any other ideas ?

Thanks in advance,
Gergő

Hello Gergo,

Could you please open a support ticket and provide a simple jsFiddle test page in which the issue you are experiencing can be observed?

Hi Rosen,

Finally the problem was resolved. The problem was, that I had a model defined for the datasource, but the model was assigned to kendoGrid's schema property not to the datasource. As soon as the  model was assigned to the datasource and not to the grid, the controls were rendered correctly.

Thank you very much for your help.

Regards,
Gergő
