You reply this post so fast !!!!
From this example you post, Datatable can be assigned to Datasource directly and my code does the same.
Environment Settings:
My Browser: IE8, Chrome and Firefox
Ext.Net Version：1.2
But GridPanel still display nothing. I post my aspx code as below:
<!-- Aspx Code-->
<ext:store ID ="InventoryQueryStore" runat="server" OnRefreshData="RefreshData" >
<Reader>
<ext:JsonReader>
<Fields>
<ext:RecordField Name = "HospitalCode" Type="String" />
<ext:RecordField Name = "MaterialCode" Type="String"/>
<ext:RecordField Name = "MaterialCName" Type="String"/>
<ext:RecordField Name = "MaterialMSpec" Type="String"/>
<ext:RecordField Name = "NowQty" Type="Int"/>
<ext:RecordField Name = "SafeDays" Type="Int"/>
<ext:RecordField Name = "SafeQty" Type="Int"/>
<ext:RecordField Name = "AverageMonthUse" Type="Int"/>
</Fields>
</ext:JsonReader>
</Reader>
</ext:store>
ext:GridPanel ID="inventoryQuery" runat="server" StoreID="InventoryQueryStore" StripeRows="true" Title = "QueryResult"
TrackMouseOver="true" Height="500px" Width="500" AutoExpandColumn="HospitalCode">
<ColumnModel>
<Columns>
<ext:Column ColumnID="HospitalCode" Header="Stockroom" Width="5%" DataIndex="HospitalCode" Align="Center" />
<ext:Column ColumnID="MaterialCode" Header="MaterialCode" Width="15%" DataIndex="MaterialCode" Align="Center" />
<ext:Column ColumnID="MaterialCName" Header="MaterialCName" Width="20%" DataIndex="MaterialCName" Align="Center" />
<ext:Column ColumnID="MaterialMSpec" Header="MaterialMSpec" Width="20%" DataIndex="MaterialMSpec" Align="Center" />
<ext:Column ColumnID="NowQty" Header="NowQty" Width="10%" DataIndex="NowQty" Align="Center"/>
<ext:Column ColumnID="SafeDays" Header="SafeDays" Width="10%" DataIndex="SafeDays" Align="Center" />
<ext:Column ColumnID="SafeQty" Header="SafeQty" Width="10%" DataIndex="SafeQty" Align="Center"/>
<ext:Column ColumnID="AverageMonthUse" Header="AverageMonthUse" Width="10%" DataIndex="AverageMonthUse" Align="Center"/>
</Columns>
</ColumnModel>
<BottomBar>
<ext:PagingToolbar ID="PagingToolbar1" runat="server" PageSize="20" StoreID="InventoryQueryStore" />
</BottomBar>
</ext:GridPanel>
Thanks for your reply.
I solved my question asked. I reallize the
data type is the cause that make something wrong.
I change Data Type and test fine!! Code is as below ：
private DataTable GenIventoryList()
{
DataTable targettbl = new DataTable();
DataTable sourcetbl = GetInventorytbl();
targettbl.Columns.AddRange(new DataColumn[] {
new DataColumn("StockRoom") {ColumnName="StockRoom", DataType=typeof(string)},
new DataColumn("MaterialCode") {ColumnName="MaterialCode", DataType=typeof(string)},
new DataColumn("MaterialCName") {ColumnName="MaterialCName", DataType=typeof(string)},
new DataColumn("MaterialMSpec") {ColumnName="MaterialMSpec", DataType=typeof(string)},
new DataColumn("StockPresentQty") {ColumnName="StockPresentQty", DataType=typeof(int)},
new DataColumn("SafetyDays") {ColumnName="SafetyDays", DataType=typeof(int)},
new DataColumn("SafetyQty") {ColumnName="SafetyQty", DataType=typeof(int)},
new DataColumn("MonthUsageQty") {ColumnName="MonthUsageQty", DataType=typeof(int)},
new DataColumn("AutoTransQty") {ColumnName="AutoTransQty", DataType=typeof(int)}
}
);
foreach (DataRow row in sourcetbl.Rows)
{
DataRow targetrow = targettbl.NewRow();
targetrow["StockRoom"] = row["StockRoom"].ToString();
targetrow["MaterialCode"] = row["MaterialCode"].ToString();
targetrow["MaterialCName"] = row["MaterialCName"].ToString();
targetrow["MaterialMSpec"] = row["MaterialMSpec"].ToString();
targetrow["StockPresentQty"] = row["StockPresentQty"] is DBNull ? 0 : Convert.ToDecimal(row["StockPresentQty"]);
targetrow["SafetyDays"] = row["SafetyDays"] is DBNull ? 0 : Convert.ToDecimal(row["SafetyDays"]);
targetrow["SafetyQty"] = row["SafetyQty"] is DBNull ? 0 : Convert.ToDecimal(row["SafetyQty"]);
targetrow["MonthUsageQty"] = row["MonthUsageQty"] is DBNull ? 0 : Convert.ToDecimal(row["MonthUsageQty"]);
targetrow["AutoTransQty"] = row["AutoTransQty"] is DBNull ? 0 : Convert.ToDecimal(row["AutoTransQty"]);
targettbl.Rows.Add(targetrow);
}
return targettbl;
}
PS. Some Columns are different from original post, but all I want to demo is the algorithm, not detail. I don't know this is good method or not.
Anyway, I solve the question....Orz...
IF YOU HAVE BETTER SOLUTION, PLEASE LET ME KNOW. YHANK YOU VERY ... VERY MUCH
