<h5 id="C1_Win_FlexGrid_IC1FlexGridRowDetail_UpdateSize_C1_Win_FlexGrid_C1FlexGrid_System_Int32_System_Drawing_Size__remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>The detail control should update its size in this method.</p>
<p>Height of the detail row will be adjusted based on the height of the control.</p>
<p>The easiest way to update size is to assign value of <code class="paramref">proposedSize</code> parameter.
The width of proposed size is the width of all cells from first non-fixed to last.
The height of proposed size is the current height of the control.</p>

<h5 id="C1_Win_FlexGrid_IC1FlexGridRowDetail_UpdateSize_C1_Win_FlexGrid_C1FlexGrid_System_Int32_System_Drawing_Size__examples">Examples</h5>
<p>The code below shows the implementation of UpdateSize method using proposedSize parameter:</p>
<pre><code class="lang-csharp">void IC1FlexGridRowDetail.UpdateSize(C1FlexGrid parentGrid, int rowIndex, Size proposedSize)
{ 
    // assign proposedSize as control's size
    Size = proposedSize; 
}</code></pre>
<p>The code below shows the basic implementation of UpdateSize method for detail control derived from C1Label:</p>
<pre><code class="lang-csharp">void IC1FlexGridRowDetail.UpdateSize(C1FlexGrid parentGrid, int rowIndex, Size proposedSize)
{ 
    // accuire size of partent grid's scrollable area
    var srSz = parentGrid.ScrollableRectangle.Size; 

    // measure the size of C1Label's text, which fits into parent's grid scrollable area width
    var sz = TextRenderer.MeasureText(Text, Font, srSz, TextFormatFlags.WordBreak);

    // chose the maximum width between scrollable area and measured text
    sz.Width = Math.Max(sz.Width, srSz.Width); 

    // assign calculated size as control's size
    Size = sz;
}</code></pre>
