    <p>I have a dropdownlist that controls the contents of 3 gridview controls. These are used in a webpart. However, every time the selectedindexchanged method of the dropdownlist fires an event, the contents of the dependent gridviews adds another rendering of a gridview. Hence, it doubles and even triples the contents of those gridviews.</p> <p>I have the following codes:</p> <p>->for the CreatChildControls method:</p> <pre><code>ProfileGrid(_gridProf, _dtProf, _infoObj, _column, _imgColumn, _ddl, _strConn, _id); Controls.Add(_gridProf); Controls.Add(new LiteralControl("&lt;br /&gt;")); PhysicalGrid(_gridPhys, _dtPhys, _infoObj, _column, _ddl, _strConn, _id); Controls.Add(_gridPhys); Controls.Add(new LiteralControl("&lt;br /&gt;")); LabGrid(_gridLab, _dtLab, _infoObj, _column, _ddl, _strConn, _id); Controls.Add(_gridLab); Controls.Add(new LiteralControl("&lt;br /&gt;")); </code></pre> <p>->for the SelectedIndexChanged method:</p> <pre><code>private void ddl_SelectedIndexChanged(object sender, EventArgs e) { ProfileGrid(_gridProf, _dtProf, _infoObj, _column, _imgColumn, _ddl, _strConn, _id); PhysicalGrid(_gridPhys, _dtPhys, _infoObj, _column, _ddl, _strConn, _id); LabGrid(_gridLab, _dtLab, _infoObj, _column, _ddl, _strConn, _id); } </code></pre> <p>->for one of the GridView Controls:</p> <pre><code>private void ProfileGrid(GridView grid, DataTable dt, InfoAccess infoObj, BoundField column, ImageField imgColumn, DropDownList ddl, string strConn, string id) { string query = "exec spr_VITALITY_SCORE '" + id + "', '" + (ddl.SelectedValue == "" ? DateTime.Now.Year.ToString() : ddl.SelectedValue.ToString()) + "'"; infoObj.StrConn = strConn; dt = infoObj.SQLResult(query); grid.DataSource = dt; column.DataField = "SCORE"; column.HeaderText = "Score"; grid.Columns.Add(column); imgColumn.DataImageUrlField = "VITALITY_COLOR"; imgColumn.DataImageUrlFormatString = "../../Style%20Library/OHImages/{0}"; imgColumn.HeaderText = "Vitality Color"; grid.Columns.Add(imgColumn); column = new BoundField(); column.DataField = "VITALITY_DEFINITION"; column.HeaderText = "Vitality Definition"; grid.Columns.Add(column); column = new BoundField(); column.DataField = "REMARKS"; column.HeaderText = "Remarks"; grid.Columns.Add(column); DesignGrid(_gridProf); _gridProf.Attributes.Add("Style", "text-align:center;"); } </code></pre> <p>The DesignGrid method only defines the attributes of the gridviews. Can anyone please assist me on this incorrect rendering problem? Thanks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
