How to get selected value in Blazor Dropdown List?

[Syncfusion Support]

Answer:

When a value is selected from a DropDown List, the OnValueSelect event is triggered. We can obtain the value by using that event. Please refer the code snippet below.

<SfDropDownList TItem="GameFields" TValue="string" PopupHeight="230px" Placeholder="Select a game" @bind-Value="@DropVal" DataSource="@Games">

<DropDownListEvents TValue="string" ValueChange="OnChange" OnValueSelect="onSelect">DropDownListEvents>

<DropDownListFieldSettings Text="Text" Value="ID">DropDownListFieldSettings>

SfDropDownList>

 Hi! 

Basically when the value get changed in the dropdown , it get passed inside the ChangeEventArgs e . 

so if you wanna make an event as OnValueSelect and implement a function for it 

first you have to make the function take a parameter of the type you wanna get from the dropDown . 
for example if the value type is string then you will make the function take a string parameter . 

and it will be like : 

<SfDropDownList TItem="GameFields" TValue="string" PopupHeight="230px" Placeholder="Select a game" @bind-Value="@DropVal" DataSource="@Games">

<DropDownListEvents TValue="string" ValueChange="OnChange" OnValueSelect="@((e)=>OnSelect(e.value))">DropDownListEvents>

<DropDownListFieldSettings Text="Text" Value="ID">DropDownListFieldSettings>

SfDropDownList>

@{

public void  OnSelect( string e ) 

{

// here u can use the e to do what u want

}

}

also i degust using ValueChange rather then OnValueSelect.
