Datagridview weird behaviour

Question

When I change a value in a cell the record is updated via a SQL Insert statement which works fine. When I don't change a value in a cell and just tab to the next cell, it removes all the current rows from the datagridview and renders a new row.

Answer 1

Try this:

 

foreach (var item in storeItem)

{

<input type="button" id="btn" value="@item.StoreItemName" onclick="addvalue($(this))" />

}

<script>

function addvalue(e) {

$('#ItemName').val(e.val())

}

</script>

Answer 2

Hi,

 

Please try like below -

 

<input type="button" id="btn" value="@item.StoreItemName" onclick="addvalue(this.value)" /> 

 

script -

 

function addvalue(myval) {

$('#ItemName').val(myval);

}

 

 The error in your question is not from the script you provided. It was coming from some other script. 

Answer 3

@if (TempData["srResult"] != null)

{

List<StoreItem> storeItem = (List<StoreItem>)TempData["srResult"];

foreach (var item in storeItem)

{

<input type="button" id="btn" value="@item.StoreItemName" onclick="addvalue()" />

}

}
