[Solved] Hirerchy Databinding using ObservableCollection

[Prakash]

Hi 

  

Can u please provide me sample how to bind the Hirerchy Grid using below collection

  

Im adding the 

ChildTableDefinitions by this way but i couldn't bind the data 

  

  

  

myGrid1.ChildTableDefinitions.Clear();

  

   

  

GridViewTableDefinition definition = new GridViewTableDefinition();

  

definition.Relation = new PropertyRelation("SubTests");

  

Radgridvw.ChildTableDefinitions.Add(definition);

  

   

  

   

  

GridViewTableDefinition definition1 = new GridViewTableDefinition();

  

definition1.Relation = new PropertyRelation("SubTest_1");

  

//Radgridvw.ChildTableDefinitions.Add(definition1);

  

  

  

definition.ChildTableDefinitions.Add(definition1);

  

This is my class and collection    

  

public ObservableCollection<Test> GetTests()

  

{ 

  

ObservableCollection<Test> Tests = new ObservableCollection<Test>();

  

Tests.Add(new Test()   

{   

Column1 = "1C1",Column2 = "1C2", Column3 = "1C3", Column4 = "1C4", Column5 = "1C5",   

SubTests = null   

});

  

Tests.Add(new Test()   

{   

Column1 = "2C12C12C1", Column2 = "2C2", Column3 = "2C3", Column4 = "2C4", Column5 = "2C5",   

SubTests = new List<SubTest>() {    

new SubTest()    

{ SubColumn1 = "S1C1",  SubColumn2 = "S1C2",
SubTests_1 = new List<SubTest_1>() { new SubTest_1() { SubColumn1_1 = "PPP", SubColumn2_1 = "VVV"},   

new SubTest_1() { SubColumn1_1 = "PPP1", SubColumn2_1 = "VVV"} }    

} ,

  

new SubTest()    

{ SubColumn1 = "S2C1",  SubColumn2 = "S2C2",
SubTests_1 = new List<SubTest_1>() { new SubTest_1() { SubColumn1_1 = "PPPPPP", SubColumn2_1 = "VVVvbbb"},

new SubTest_1() { SubColumn1_1 = "PPP1", SubColumn2_1 = "VVVererer"} } } 

}

});

  

Tests.Add(new Test()   

{  

Column1 = "3C1", Column2 = "3C23C23C23C2", Column3 = "3C3", Column4 = "3C4", Column5 = "3C5",

SubTests = new List<SubTest>() { 

new SubTest() { SubColumn1 = "S1C1", SubColumn2 = "S1C2",

SubTests_1 = new List<SubTest_1>() { new SubTest_1() { SubColumn1_1 = "PPP7777", SubColumn2_1 = "VVV5656"},

new SubTest_1() { SubColumn1_1 = "PPP1141", SubColumn2_1 = "VVV7825"} }} ,

new SubTest() { SubColumn1 = "S2C1", SubColumn2 = "S2C2",

SubTests_1 = new List<SubTest_1>() { new SubTest_1() { SubColumn1_1 = "PPP776666", SubColumn2_1 = "VVV4444"},

new SubTest_1() { SubColumn1_1 = "PPP1", SubColumn2_1 = "VVV"} }} 

}

});

  

Tests.Add(new Test()

  

{

  

Column1 = "4C1",

  

Column2 = "4C2",

  

Column3 = "4C34C34C34C34C3",

  

Column4 = "4C4",

  

Column5 = "4C5",

  

SubTests = new List<SubTest>() { 

  

new SubTest() { SubColumn1 = "S1C1", SubColumn2 = "S1C2" } ,

  

new SubTest() { SubColumn1 = "S2C1", SubColumn2 = "S2C2" } 

  

}

  

});

  

Tests.Add(new Test()

  

{

  

Column1 = "5C1",

  

Column2 = "5C2",

  

Column3 = "5C3",

  

Column4 = "5C4",

  

Column5 = "5C5",

  

SubTests = new List<SubTest>() { 

  

new SubTest() { SubColumn1 = "S1C1", SubColumn2 = "S1C2" } ,

  

new SubTest() { SubColumn1 = "S2C1", SubColumn2 = "S2C2" } 

  

}

  

});

  

return Tests; 

  

}

I can bind 1st level of hirerchy by

<

 

 

my:iGrid.ChildTableDefinitions>

 

 

 

 

<my:iGridViewTableDefinition>

 

 

 

 

<my:iGridViewTableDefinition.Relation>

 

 

 

 

<my:iPropertyRelation ParentPropertyName="SubTests" />

 

 

 

 

</my:iGridViewTableDefinition.Relation>

 

 

 

 

</my:iGridViewTableDefinition>

 

 

 

 

</my:iGrid.ChildTableDefinitions>

 

How can i bind the next level (SubTest_1)

Hello Prakash,

In this case you need to define a HierarchyChildTemplate, put a gridview in it and define its ChildTableDefinitions.
Find attached a sample project.
