WPF从网格删除行 [英] WPF Delete Row from grid

问题描述

我对WPF很新，并且正在使用WPF构建一个Charting应用程序。我正在动态添加新行，并且它完美地工作。删除行时出现问题。这是我添加行的代码

  RowDefinition newRow = new RowDefinition（）; 
 newRow.Name =ADX; 
 newRow.Height = new GridLength（1，GridUnitType.Star）; 
 this.chartForm.sciChartControl.ContentGrid.RowDefinitions.Add（newRow）; 
 Grid.SetRow（scs，this.chartForm.sciChartControl.ContentGrid.RowDefinitions.Count  -  1）; 
 this.techIndicatorToRowDefinitionMap [ADX] = newRow; 
  

和删除行的代码是

  this.chartForm.sciChartControl.ContentGrid.RowDefinitions.Remove（this.techIndicatorToRowDefinitionMap [ ADX]）; 
  

当我删除这些行时，似乎随机行被删除。你能告诉我是否有更简单的方法来跟踪行并删除它们，或者是否存在此代码中的错误。

谢谢。

解决方案您好，我认为您的代码正确地移除了RowDefinition，但是我认为错误的是您还需要移除该行中Grid的子项，如

  this.chartForm.sciChartControl.ContentGrid.Children.Remove（scs）; 
 this.chartForm.sciChartControl.ContentGrid.RowDefinitions.Remove（this.techIndicatorToRowDefinitionMap [ADX]）; 
  

如果您不移除子元素，RowDefinition将被移除，但子元素将被移至另一行。希望这会给你一个主意。

I am pretty new to WPF and am building an Charting application using WPF. I am adding new rows dynamically and it works perfectly. I am seeing a problem when removing rows. This is my code for adding rows

RowDefinition newRow = new RowDefinition();
newRow.Name = "ADX";
newRow.Height = new GridLength(1, GridUnitType.Star);
this.chartForm.sciChartControl.ContentGrid.RowDefinitions.Add(newRow);
Grid.SetRow(scs, this.chartForm.sciChartControl.ContentGrid.RowDefinitions.Count - 1);
this.techIndicatorToRowDefinitionMap["ADX"] = newRow;

and the code to remove the Row is

this.chartForm.sciChartControl.ContentGrid.RowDefinitions.Remove(this.techIndicatorToRowDefinitionMap["ADX"]);

When I remove the rows , it seems like random rows are removed. Can you tell me if there is an easier way to keep track of rows and delete them or if there is a bug in this code .

Thanks.

解决方案

Hi I think your code is Removeing the RowDefinition correctly but what I think wrong is you also need to remove the children of Grid in that Row like

this.chartForm.sciChartControl.ContentGrid.Children.Remove(scs);
this.chartForm.sciChartControl.ContentGrid.RowDefinitions.Remove(this.techIndicatorToRowDefinitionMap["ADX"]);

If you wont remove the child the RowDefinition will be removed but child will be shifted to another row .I hope this will give you an idea.
