Hi Maya,

  Thanks for replying.

   I am using Infragistics35.Web.v11.2, Version=11.2.20112.2159.

   The values are set in javascript as soon as I click any cell in the AddNewRow present at the bottom using RowAdding_EnteringEditMode event.

   And the values doesnot contain any special characters. It is a string containing years to select from the dropdown. 

 The logic here follows to set the year dropdown to next year which is not already chosen.

function grdCreditUtilRt_RowAdding_EnteringEditMode(sender, eventArgs) {
var row = eventArgs.getCell().get_row();
if (row.get_cell(0).get_text() == "") {
var years = document.getElementById("hiddenVar").value.split(";"); //hiddenVar='1999;2000;2001;2002;'
var year = igcmbo_getComboById("comboId").displayValue;
for (i = 1; i < years.length; i++) {
if (document.getElementById("hiddenYears").value.indexOf(years[i]) == -1) { //hiddenyears = '2000;2002;' These are already chosen years.
row.get_cell(0).set_text(years[i].toString());
row.get_cell(0).set_value(years[i]);
break;
}
}
if (i == years.length) {
alert("custom message");
eventArgs.set_cancel(true);
}
}

row.get_cell(3).set_text("A");
if (row.get_cell(1).get_text() == "")
row.get_cell(1).set_text("0");
if (row.get_cell(2).get_text() == "")
row.get_cell(2).set_text("0");
if (row.get_cell(4).get_text() == "")
row.get_cell(4).set_value(parseInt($find('grid').get_rows().get_length())+1); // This is the row count, which is set to DataKeyFields
}

Hi,

 I am facing the issue yet.  Can anyone help me in resolving the issue.

The following error occurs when a Webdropdown option present in the cell is changed for the first time and row is added to the grid and when a postback occurs the following exception occurs.

The exception wont occur if we add the row with the default values set in the rowentering javascript event and code dont break anywhere after that.

Invalid JSON primitive: |0|2007&tilda;37||.

Hi Maya,

 I have a simple requirement to allow the user to add a row to the grid. I am using the Row Adding Behavior of the WebDataGrid

 Do I need to set the DataKeyFields Property to the primary key of the datasource, which is the identity column too in my case.

Also my webdatagrid is build in the Business Logic layer.

I would like to update all the rows together added or edited or deleted. For which I enabled BatchUpdate="true".

When I add the row into the grid, how to set the primary key column value in RowAdding_EnteringEditMode.

I would like to know if there is any possibility that I can use the Row Adding Behavior without setting the DataKeyFields Property by manually looping the rows , in that way I want to just insert the data which I populated into the grid without bothering about the primary key column field.

Regards,

Sudharshan.

Hi Maya,

 Thanks for the Sample. My requirement got changed to ineditable cell rather than a dropdown. I need not look into the issue as of now.

 I need assistance in getting the information of the row if it is edited or newly added or deleted if any.

I am using following Lines to know if the grid row is edited or added. Is this correct way to do that. I am using these lines of code in Button_click event.

bool isRowEdited=((System.Data.DataRowView)(((Infragistics.Web.UI.GridControls.ControlDataRecord)(grid.Rows[i])).DataItem)).IsEdit;

bool isRowAdded=((System.Data.DataRowView)(((Infragistics.Web.UI.GridControls.ControlDataRecord)(grid.Rows[i])).DataItem)).IsNew;

If these are correct. Then how to get the rows which are deleted.

Regards,

Sudharshan.

Hello Sudharshan, 

I’ve tested this scenario on my side with the same version you’re using but was unable to reproduce this on my side.

Please refer to the attached sample and let me know if I’m missing something from your scenario. If possible please modify the sample so that it will reproduce the issue or provide your own sample that produces the issue.

I’m looking forward to your reply.

Best Regards,

Maya Kirova
