Dropdown in Grid Issue

[Joseph Orjinta]

Hello,

 

I have issues with populating Dropdown in Grid, The Dropdown comes up with

'System.Collections.Generic.Dictionary`2[System.String, System.Object]  items populated in the dropdown list.

 

This is code at the controller

 

public class AdminController : Controller

{

private IChapterRepository repositoryChapter;

private IBranchRepository repositoryBranch;

public AdminController(IChapterRepository chapterRepository, IBranchRepository branchRepository)

{

this.repositoryChapter = chapterRepository;

this.repositoryBranch = branchRepository;

}

/// <summary>

/// Used for rendering the grid initially.

/// </summary>

/// <returns>Veiw page, it displays the Grid</returns>

public ActionResult Chapters()

{

　

ViewData[

"BranchCode"] = BranchList;

var data = repositoryChapter.Chapters.ToList();

return View(data);

}

public IEnumerable<SelectListItem> BranchList

{

get

{

List<SelectListItem> type = new List<SelectListItem>();

var branches = repositoryBranch.Branches;

foreach (var branch in branches)

{

type.Add(

new SelectListItem

{

Text = branch.BranchName,

Value = branch.BranchCode

});

}

return type;

}

}

....

 

CODE AT THE CSHTML

.Datasource(Model)

.ActionMode(Syncfusion.Mvc.Grid.

ActionMode.Server)

.Caption(

"Chapters").Scrolling(s => s.Height(300))

.Column(column =>

{

column.Add(c => c.ChapterId).HeaderText(

"Chapter ID").TextAlign(Syncfusion.Mvc.Grid.TextAlignment.Left).Width(100);

column.Add(c => c.ChapterName).HeaderText(

"Chapter Name").TextAlign( Syncfusion.Mvc.Grid.TextAlignment.Left).Width(100);

column.Add(c => c.ChapterFullName).HeaderText(

"Chapter Full Name").Width(130);

column.Add(c => c.BranchCode).HeaderText(

"Branch").CellEditType(CellEditType.DropdownEdit).Width(130).DropDownDataSource((System.Collections.IEnumerable)ViewData["BranchCode"]);

column.Add(c => c.EmailAddress).HeaderText(

"Email Address").Width(110);

})

.EnablePaging()

.EnableSorting()

.AutoFormat(Syncfusion.Mvc.Shared.

Skins.Marble)

Hi Joseph,

Thanks for your interest in Syncfusion products.

 

I have created a sample based on your code snippet. Could you use that sample and reproduce the error if any. We have resolved your issue by giving the name of the dataTextField and dataValueField in DropDownDataSource method.

 

Please refer the below online documentation link:

http://help.syncfusion.com/UG/ASP.NET%20MVC/Grid/documents/databindingsupportfo.htm

For your convenience we have attached a sample and screenshot. Could you use that sample and get back to us if you have any queries.

 

Let us know if you have any concerns.

 

Regards,

Abdul Matin M
