Namespace: DevExpress.Blazor
Assembly: DevExpress.Blazor.v22.1.dll
NuGet Package: DevExpress.Blazor
Declaration
[DefaultValue(3)]
[Parameter]
public int FilterMinLength { get; set; }
Property Value
Type | Default | Description |
---|---|---|
Int32 | 3 | The minimum length. |
Remarks
Use the FilterMinLength property to specify the FilterString property value’s length at which the component starts to filter its items. If the FilterString length is less than FilterMinLength, the component does nothing. Note that this property also affects filter operations executed from code.
In the following example, an error message appears if a user types less than 4 characters in the search panel:
<DxAccordion ShowFilterPanel="true"
FilterStringChanged=@OnFilterStringChanged
FilterMinLength="4"
CssClass="cw-480"
Data="@Data">
<DataMappings>
<DxAccordionDataMapping ParentKey="CategoryId"
Key="Id"
Text="Name" />
</DataMappings>
</DxAccordion>
@Message
@code {
string Message = "";
void OnFilterStringChanged(string NewString) {
if (NewString == null || NewString.Length < 4)
Message = "You need to enter at least 4 characters to apply the filter";
else
Message = "";
}
@* ... *@
}
