Prevent Drag Selection from input in Columns Template

[Alexander Kuhlmann]

Hey,

I have an Tree grid with these settings:

    <SfTreeGrid DataSource="@GridItems" IdMapping="Id" ParentIdMapping="ParentId" TreeColumnIndex="0" AllowRowDragAndDrop="true" AllowSelection="true">

        <TreeGridSelectionSettings Type="Syncfusion.Blazor.Grids.SelectionType.Multiple" Mode="Syncfusion.Blazor.Grids.SelectionMode.Row" AllowDragSelection="false"></TreeGridSelectionSettings>

and one of my columns have these definition:

 <TreeGridColumn Field="Price" HeaderText="Preis">

     <Template>

         @{

             if (context is TreeGridPositionWrapper item)

             {

                 if (item.BasePosition is MDetailPosition p)

                 {

                     <div @onclick:preventDefault="true" @onclick:stopPropagation="true"

                          @ondblclick:preventDefault="true" @ondblclick:stopPropagation="true"

                          @onmousedown:preventDefault="true" @onmousedown:stopPropagation="true"

                          @onmouseup:preventDefault="true" @onmouseup:stopPropagation="true"

                          @onmousemove:preventDefault="true" @onmousemove:stopPropagation="true"

                          @onpointerdown:preventDefault="true" @onpointerdown:stopPropagation="true"

                          @onpointerup:preventDefault="true" @onpointerup:stopPropagation="true"

                          @onpointermove:preventDefault="true" @onpointermove:stopPropagation="true"

                          @ontouchstart:preventDefault="true" @ontouchstart:stopPropagation="true"

                          @ontouchend:preventDefault="true" @ontouchend:stopPropagation="true"

                          @ondragstart:preventDefault="true" @ondragstart:stopPropagation="true"

                          @ondrag:preventDefault="true" @ondrag:stopPropagation="true"

                          @ondragend:preventDefault="true" @ondragend:stopPropagation="true">

                         <SfNumericTextBox TValue="decimal" ShowSpinButton="false" Format="C2"

                                           @onclick:stopPropagation="true"

                                           @ondblclick:stopPropagation="true"

                                           @onmousedown:stopPropagation="true"

                                           @onmousemove:stopPropagation="true"

                                           @onmouseup:stopPropagation="true"

                                           @onpointerdown:stopPropagation="true"

                                           @onpointerup:stopPropagation="true"

                                           @onpointermove:stopPropagation="true"

                                           @ontouchstart:stopPropagation="true"

                                           @ontouchend:stopPropagation="true"

                                           @ondragstart:stopPropagation="true"

                                           @ondrag:stopPropagation="true"

                                           @ondragend:stopPropagation="true"></SfNumericTextBox>

                     </div>

                 }

             }

         }

     </Template>

 </TreeGridColumn>

But if I drag the mouse inside the NumericTextBox to select the some Chars the grid starts drag selection.

How ca I prevent this?

As you can see, I tried to stop the propagation of many events, but this is not working.

Best wishes

Alex

Hi Sreddhar, 

before I tried the way I described here, I tried the solution from the other thread, without success.

But now I found a solution, I had to fix various things in the js scripts and now it is working.

Thank you.
