Hi,

I have the same problem with Tan. The radgrid has 3 hierarchies, and each hierarchy has a custom command item for Add,Edit and Delete. My problem is, how to handle the event of linkbutton inside the detail table (GridTableView Name Detail2 and 3)?

Below is my aspx

<rad:RadGrid runat="server" ID="gridCPDiag" AllowPaging="True" AllowSorting="True" PageSize="15"

AutoGenerateColumns="False" GridLines="None" BorderStyle="None" Skin="Outlook"

OnNeedDataSource="gridCPDiag_NeedDataSource"

OnDetailTableDataBind="gridCPDiag_DetailTableDataBind"

OnInsertCommand="gridCPDiag_InsertCommand"

OnUpdateCommand="gridCPDiag_UpdateCommand"

OnDeleteCommand="gridCPDiag_DeleteCommand"

OnPreRender="gridCPDiag_PreRender" OnItemDataBound="gridCPDiag_ItemDataBound">

Hello Lyzel,

The RadGrid.ItemCommand event will be fired when a custom command bubbles from the CommandItem, which lets you define custom functionality that can be executed in the ItemCommand handler. And you can check with the name of OwnerTableView to identify the operaion for MasterTable/DetailTables.

C#:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == "InitInsert" && e.Item.OwnerTableView.Name == "Master")

//for Add Button in MasterTableView

{

}

if (e.CommandName == "InitInsert" && e.Item.OwnerTableView.Name == "Detail2")

//for Add Button in Detail2

{

}

if (e.CommandName == "InitInsert" && e.Item.OwnerTableView.Name == "Detail3")

//for Add Button in Detail3

{

}

Thanks,
Princy.

Hi Princy,

Thanks for your reply. But I have another problem, how to show/hide some link buttons after clicking the Add or Edit? Even though i set the property of link button to true, it will not appear in the command item.

Kindly check my code below.

protected void gridCPDiag_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.Item.OwnerTableView.Name == "Detail2")

{

if (e.Item is GridCommandItem)

{

GridCommandItem commandItem = e.Item as GridCommandItem;

LinkButton btnAdd = commandItem.FindControl("btnAdd") as LinkButton;

LinkButton lnkPerformInsert = commandItem.FindControl("lnkPerformInsert") as LinkButton;

LinkButton btnEditSelected = commandItem.FindControl("btnEditSelected") as LinkButton;

LinkButton btnUpdateEdited = commandItem.FindControl("btnUpdateEdited") as LinkButton;

LinkButton btnCancel = commandItem.FindControl("btnCancel") as LinkButton;

LinkButton btnDelete = commandItem.FindControl("btnDelete") as LinkButton;

btnAdd.Visible = false;

btnEditSelected.Visible = false;

btnDelete.Visible = false;

if (e.CommandName == "InitInsert")

{

lnkPerformInsert.Visible = true;

btnCancel.Visible = true;

}

if (e.CommandName == "EditSelected")

{

btnUpdateEdited.Visible = true;

btnCancel.Visible = true;

}

Thanks!

Hello Lyzel,

You can try this in ItemDataBound event. In ItemCommand event you can identify which operation is performing and store the opeartion name in a hiddenField .Then in ItemDataBound event based on this HiddenField value, hide the corresponding controls. Check out the sample code.

C#:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)

{

if(e.Item.OwnerTableView.Name == "Detail2")

{

if (e.CommandName == "InitInsert")

{

HiddenField1.Value = "InitInsert";

}

else if(e.CommandName == "EditSelected")

{

HiddenField1.Value = "EditSelected";

}

. . . . . .. . . . . . . . . . . . . . . .

}

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridCommandItem && e.Item.OwnerTableView.Name == "Detail2")

{

GridCommandItem commandItem = (GridCommandItem)e.Item;

LinkButton lnkPerformInsert = commandItem.FindControl("lnkPerformInsert") as LinkButton;

LinkButton btnEditSelected = commandItem.FindControl("btnEditSelected") as LinkButton;

LinkButton btnUpdateEdited = commandItem.FindControl("btnUpdateEdited") as LinkButton;

LinkButton btnCancel = commandItem.FindControl("btnCancel") as LinkButton;

LinkButton btnDelete = commandItem.FindControl("btnDelete") as LinkButton;

if (HiddenField1.Value == "InitInsert")

{

lnkPerformInsert.Visible = true;

btnEditSelected.Visible = false;

btnUpdateEdited.Visible = false;

btnCancel.Visible = true;

btnDelete.Visible = false;

}

else if (HiddenField1.Value == "EditSelected")

{

lnkPerformInsert.Visible = false;

btnEditSelected.Visible = false;

btnUpdateEdited.Visible = true;

btnCancel.Visible = true;

btnDelete.Visible = false;

}

else

{

lnkPerformInsert.Visible = true;

btnEditSelected.Visible = true;

btnUpdateEdited.Visible = true;

btnCancel.Visible = true;

btnDelete.Visible = true;

}

Thanks,
Princy.

ClinicalPathway cp = new ClinicalPathway(AgencyId, BranchId);

char mode = 'i';

cp.UpdateVisitInstruction(-1, SelectedCPVisitFreq, txtInstr.Text, Convert.ToInt32(txtSortOrder.Text), mode);

insertItem.Edit = false;

} The data was successfully added to the database, but an error will occur "Insert item is available only when grid is in insert mode."

Hello Zel,

Straight to your questions:

Please take a look at the Referencing controls in grid row/edit form help topic to see how to find the desired control.
You can use the approach from the Retain expanded/selected state in hierarchy on rebind code library.
Please examine the Select Last Inserted Row in the RadGrid with both Paging and Sorting enabled code library to see how this functionality can be achieved.
Please check the Inserting values in-place and EditForms help topic to learn the proper ways to insert grid rows with InPlace and EditForms edit mode.

I hope this helps.

Hello Everyone,

I already tried the code in Retain expanded/selected state in hierarchy on rebind. But I have a problem, every time I click on edit command item in detail 3 the other command item for detail 2 and master table also changes.

Please see the attached screenshots Before and After clicking the edit command item in detail 3.

Below is my C# code for customizing the visibility of command items.

LinkButton visitlnkPerformInsert = (LinkButton)visitcommandItem.FindControl("lnkPerformInsert");

LinkButton visitbtnEditSelected = (LinkButton)visitcommandItem.FindControl("btnEditSelected");

LinkButton visitbtnUpdateEdited = (LinkButton)visitcommandItem.FindControl("btnUpdateEdited");

LinkButton visitbtnCancel = (LinkButton)visitcommandItem.FindControl("btnCancel");

LinkButton visitbtnDelete = (LinkButton)visitcommandItem.FindControl("btnDelete");

if (CommandState == "initinsert" || CommandState == "editselected")

{

visitbtnAdd.Visible = false;

visitbtnEditSelected.Visible = false;

visitbtnDelete.Visible = false;

visitbtnCancel.Visible = true;

{

visitbtnAdd.Visible = true;

visitbtnEditSelected.Visible = true;

visitbtnDelete.Visible = true;

visitlnkPerformInsert.Visible = false;

visitbtnUpdateEdited.Visible = false;

visitbtnCancel.Visible = false;

}

if (e.Item is GridCommandItem && e.Item.OwnerTableView.Name == "Detail3")

{

GridCommandItem inscommandItem = (GridCommandItem)e.Item;

LinkButton insbtnAdd = (LinkButton)inscommandItem.FindControl("btnAdd");

LinkButton inslnkPerformInsert = (LinkButton)inscommandItem.FindControl("lnkPerformInsert");

LinkButton insbtnEditSelected = (LinkButton)inscommandItem.FindControl("btnEditSelected");

LinkButton insbtnUpdateEdited = (LinkButton)inscommandItem.FindControl("btnUpdateEdited");

LinkButton insbtnCancel = (LinkButton)inscommandItem.FindControl("btnCancel");

LinkButton insbtnDelete = (LinkButton)inscommandItem.FindControl("btnDelete");

if (CommandState == "initinsert" || CommandState == "editselected")

{

insbtnAdd.Visible = false;

insbtnEditSelected.Visible = false;

insbtnDelete.Visible = false;

insbtnCancel.Visible = true;

}

if (CommandState == "initinsert")

{

inslnkPerformInsert.Visible = true;

}

if (CommandState == "editselected")

{

insbtnUpdateEdited.Visible = true;

}

if (CommandState == "performinsert" || CommandState == "update" || CommandState == "cancelall")

{

insbtnAdd.Visible = true;

insbtnEditSelected.Visible = true;

insbtnDelete.Visible = true;

inslnkPerformInsert.Visible = false;

insbtnCancel.Visible = false;

}

Please help.

Thanks!

Please help me with my problem that i posted last 2 days ago. I really have no idea, why is the command items for master table and detail table 2 changes, every time i click on edit in detail table 3.

Hello Zel,

I looked through your code and I cannot see an obvious reason for the described issue.
Please send us a small working project, demonstrating your full setup and showing the unwanted behavior.
We will debug it locally and get back to you.

Thank you in advance for the cooperation.

Kind regards,
Mira
