RadGrid table view

[Olga]

Hello, I have a page with multiple tables, and view of one of the table change after I add rows to it's child table. Does anybody know what issue can cause it. I don't have a errors, not in the compiler not in the browser. It stops highlighting the parent row, maybe instead it's trying to do some thing else ....

Hi Olga,

From the provided screenshots and information it is really hard to determine what is your exact scenario and how the grids are related to each other.

Could you please elaborate on your scenario, the page structure and the relationships between the grids.

I am looking forward to your reply.

I fixed, issue were at this code

        if (e.Item is GridDataItem)

        {

            GridDataItem item = (GridDataItem)e.Item;

 

            if ((projectTasks.MasterTableView.GetColumn("subtask") as GridButtonColumn).Text.ToLower() == "subtask") // ListItemType.Item)

            {

                ccSubTask subTask = new ccSubTask(sql);

                GridDataItem deleteItem = e.Item as GridDataItem;

                int id = Convert.ToInt32(deleteItem.OwnerTableView.DataKeyValues[deleteItem.ItemIndex]["id"].ToString());

                if (subTask.GetAllGrid(id).Rows.Count > 0)

                {

                    e.Item.CssClass = "TimeCss";

                }

            }

        }

 

 

and code from front side

 

    <style>

        TimeCss {

            color: red !important;

        }

 

    </style>

It is probably conflicted with css for the page, any way I comment it and it is working fine!
